- The present invention is directed to dynamic fixation assemblies for use in bone surgery, particularly spinal surgery, and in particular to longitudinal connecting members and cooperating bone anchors or fasteners for such assemblies, the connecting members being attached to at least two bone anchors.
- Historically, it has been common to fuse adjacent vertebrae that are placed in fixed relation by the installation therealong of bone screws or other bone anchors and cooperating longitudinal connecting members or other elongate members. Fusion results in the permanent immobilization of one or more of the intervertebral joints. Because the anchoring of bone screws, hooks and other types of anchors directly to a vertebra can result in significant forces being placed on the vertebra, and such forces may ultimately result in the loosening of the bone screw or other anchor from the vertebra, fusion allows for the growth and development of a bone counterpart to the longitudinal connecting member that can maintain the spine in the desired position even if the implants ultimately fail or are removed. Because fusion has been a desired component of spinal stabilization procedures, longitudinal connecting members have been designed that are of a material, size and shape to largely resist bending (flexion, extension and lateral), torsion, shear, distraction and compression, and thus substantially immobilize the portion of the spine that is to be fused. Thus, longitudinal connecting members are typically uniform along an entire length thereof, and usually made from a single or integral piece of material having a uniform diameter or width of a size to provide substantially inelastic rigid support in all planes.
- An alternative to fusion, which immobilizes at least a portion of the spine, and the use of more rigid longitudinal connecting members or other rigid structure has been a “soft” or “dynamic” stabilization approach in which a flexible loop-, S-, C- or U-shaped member or a coil-like and/or a spring-like member is utilized as an elastic longitudinal connecting member fixed between a pair of pedicle screws in an attempt to create, as much as possible, a normal loading pattern between the vertebrae in flexion, extension, side bending, distraction, compression and torsion. Another type of soft or dynamic system known in the art includes bone anchors connected by flexible cords or strands, typically made from a plastic material. Such a cord or strand may be threaded through cannulated spacers that are disposed between adjacent bone anchors when such a cord or strand is implanted, tensioned and attached to the bone anchors. The spacers typically span the distance between bone anchors, providing limits on the bending, movement of the cord or strand and thus strengthening and supporting the overall system. Shear forces are not well resisted by the typical cord and spacer stabilization systems. Such tensioned cord and spacer systems may also cause facet joint compression during spinal movement, especially flexion.
- The complex dynamic conditions associated with spinal movement create challenges for the design of elongate elastic longitudinal connecting members that exhibit an adequate fatigue strength to provide stabilization and protected motion of the spine, without fusion, and that allow for some natural movement of the portion of the spine being reinforced and supported by the elongate elastic or flexible connecting member. A further challenge are situations in which a portion or length of the spine requires a more rigid stabilization, possibly including fusion, while another portion or length may be better supported by a more dynamic system that allows for protective movement.
- A longitudinal connecting member assembly according to the invention has an inner elongate core of circular or non-circular cross-section that is integral or otherwise fixed to a first bone anchor attachment portion. A first elastic spacer surrounds the core and is slidable along the core at a location between a pair of adjacent bone anchors. At least one outer inelastic sleeve or tube-like trolley member also surrounds the core and is in sliding relationship with the core. The outer sleeve also engages at least one bone anchor. A second elastic spacer of durometer or geometry differing from the first elastic spacer also surrounds the core and is located at a side of the at least one sleeve member opposite the first elastic spacer. The inner core, elastic spacers and inelastic sleeve or sleeves cooperate dynamically, with the spacers being at least somewhat pre-compressed resulting in little-to-no or more substantial deformation of the spacers prior to insertion, and controlling movement of the sleeve allowing greater travel of the sleeve along the core in a single direction; for example, advantageously allowing greater operative travel of the sleeve in a cephalad or cranial direction and more limited movement in a caudal or caudad direction after insertion. In addition, in certain embodiments, the sleeve or tube trolley members feature inner surfaces having non-linear relief for improved core member function with respect to bending stress, wear and fatigue life concerns.
- In another embodiment, an improved longitudinal connecting member adapted for cooperating with a plurality of bone anchors that are implanted in a patient's spine is provided, wherein the longitudinal connecting member includes a substantially rigid anchor portion that extends along a longitudinal axis of the connecting member and is joined with a core portion that also extends along the longitudinal axis. The anchor portion formed of a first material and the core portion is formed of a second material. The core portion includes a reduced diameter relative to the anchor portion, such that the second material and the reduced diameter cooperate so as to enable at least some flexing of the core portion. The anchor portion is directly engaged by first and second bone anchors while the core portion is indirectly engaged by a third bone anchor. Furthermore, the longitudinal connection member provides for greater movement in the cephalad direction than in the caudad direction.
- A first inelastic sleeve is slidingly received over the core portion so as to be located between the third bone anchor and the core portion. A pair of elastic spacers is received over the core portion such that each of the spacers is adjacent to an end of the first sleeve. A crimp ring engages the core portion and is located so as to bias the spacers. Additionally, an elastic over-mold surrounds at least one of the spacers and a respective adjacent end of the first sleeve.
- In a further embodiment, the elastic over-mold grips both the anchor portion and the first sleeve.
- In another further embodiment, the anchor portion includes has a first end plate and the elastic over-mold is molded about the first end plate.
- In some further embodiments, the elastic over-mold is made from a composite material comprising elongate reinforcement strands imbedded in a polymer.
- In some further embodiments, the core is made from a polymer. Furthermore, in some embodiments, the polymer is polyetheretherketone.
- In another further embodiment, the first sleeve substantially blocks flexing of the portion of the core that is surrounded by the first sleeve. Additionally, in some embodiments, the core flexes primarily between the first sleeve and the anchor portion.
- In yet another further embodiment, the longitudinal connecting member also includes a second inelastic sleeve slidingly received over the core portion so as to be located between a fourth bone anchor and the core portion; a third elastic spacer received over the core portion so as to be located between the second inelastic sleeve and the crip ring; and a second elastic over-mold surrounding a second end of the first sleeve, the third spacer and an adjacent end of the second sleeve. In some embodiments, the first sleeve substantially blocks flexing of the portion of the core that is surrounded by the first sleeve; and the second sleeve substantially blocks flexing of the portion of the core that is surrounded by the second sleeve. Accordingly, in some embodiments, the core flexes primarily between the first sleeve and the anchor portion; and between the first sleeve and the second sleeve.
- An object of the invention is to provide dynamic medical implant stabilization assemblies having longitudinal connecting members that include a flexible, pre-tensioned portion that can allow for controlled bending, torsion, compression and distraction of the assembly. Another object of the invention is to provide such an assembly including elastic pre-compressed spacers of various durometers and/or geometries. A further object of the invention is to provide dynamic medical implant longitudinal connecting members that may be utilized with a variety of bone screws, hooks and other bone anchors. Additionally, it is an object of the invention to provide a lightweight, reduced volume, low profile assembly including at least two bone anchors and a longitudinal connecting member therebetween. Furthermore, it is an object of the invention to provide apparatus and methods that are easy to use and especially adapted for the intended use thereof and wherein the apparatus are comparatively inexpensive to make and suitable for use.

- With reference to
FIGS. 1-37 , thereference numeral 1 generally designates a non-fusion dynamic stabilization longitudinal connecting member assembly according to the present invention. The connectingmember assembly 1 includes an inelastic anchor member, generally 4, having an inelastic elongateinner core 6 extending from a boneanchor attachment portion 8; a first elasticdifferential compression spacer 10; a first hard or inelastic contouredpressure washer 11; a first inelastic sleeve orsleeve trolley 12; a second inelastic contouredpressure washer 13; a second elasticdifferential compression spacer 14; a third inelastic contouredpressure washer 15; a secondinelastic sleeve 16; a third elastic differential compression spacer orelastic bumper 18; and an inelastic crimpingring 20; all substantially symmetrically aligned with respect to a central axis A of theanchor member 4. Theelongate core 6 of theanchor member 4 is receivable within the spacers, sleeves, pressure washers, bumper and crimping ring. Thus, the axis A of theanchor member 4 is also the axis of the fully assembledassembly 1. An optional over-molded sleeve or casing 22 can surround a portion of theanchor member 4 extending to the boneanchor attaching portion 8, thespacer 10, thewasher 11 and a portion of thesleeve 12. A second over-molded sleeve or casing 23 surrounds a portion of thesleeve 12, thewasher 13, thespacer 14, thewasher 15 and a portion of thesleeve 16. As will be described in greater detail below, when fully assembled and all components fixed in position, as shown inFIGS. 1 , 2 and 4, for example, thespacers bumper 18 are in compression, with the moreelastic bumper 18 shown being slightly deformed and bulging outwardly due to the compressive force placed thereupon. The pre-compressed spacers and bumpers in turn place axial forces upon thesleeves FIG. 2 illustrates placement of theassembly 1 and cooperating bone screws as positioned along a human spine with theelastic bumper 18 being at a top or upper position, thebumper 18 andspacers assembly 1 in a cephalad or cranial direction and more limited movement in a caudad direction. - As illustrated in
FIG. 2 , the dynamic connectingmember assembly 1 cooperates with at least three bone anchors and is illustrated with four bone anchors in the form of polyaxial bone screws, generally 25, theassembly 1 being captured and fixed in place at theanchor portion 8, theinelastic sleeve 12 and theinelastic sleeve 16 by the bone screws 25. Because theanchor portion 8 and thesleeves member assembly 1 may be used with a wide variety of bone screws and other bone anchors already available for cooperation with more rigid rods including fixed, monoaxial bone screws, hinged bone screws, polyaxial bone screws, and bone hooks and the like, with or without compression inserts, that may in turn cooperate with a variety of closure structures having threads, flanges, or other structure for fixing the closure structure to the bone anchor, and may include other features, for example, external or internal drives, break-off tops and inner set screws. The bone anchors, closure structures and the connectingmember assembly 1 are then operably incorporated in an overall spinal implant system for correcting degenerative conditions, deformities, injuries, or defects to the spinal column of a patient. - In the particular embodiment of the
assembly 1 being illustrated herein, wherein thesleeves inner core 6. In particular, with reference toFIGS. 29 , 30 and 31, the illustrated polyaxial screws 25 each include ashank 27, a receiver orhead 28, alower pressure insert 29, anupper pressure insert 30 and a closure structure, generally 32 that further includes andouter fastener 33 and aninner set screw 34. The illustratedshank 27 for insertion into a vertebra (not shown) is pivotally attached to the open receiver orhead 28. Theshank 27 includes a threaded outer surface and optionally includes a central cannula or through-bore disposed along an axis of rotation of theshank 27. The through bore provides a passage through the shank interior for a length of wire or pin inserted into the vertebra prior to the insertion of theshank 27, the wire or pin providing a guide for insertion of theshank 27 into the vertebra. Thereceiver 28 includes a pair of spaced and generally parallel arms that form an open generally U-shaped channel therebetween that is open at distal ends of such arms. The receiver arms each include radially inward or interior surfaces that have a discontinuous guide and advancement structure mateable with cooperating structure on theouter fastener 33. The guide and advancement structure may be a partial helically wound flangeform configured to mate under rotation with a similar structure on theouter fastener 33 or a buttress thread, a square thread, a reverse angle thread or other thread like or non-thread like helically wound advancement structures for operably guiding under rotation and advancing thefastener 33 downward between the receiver arms and having such a nature as to resist splaying of the receiver arms when thefastener 33 is advanced between the receiver arms. - The illustrated
shank 27 is top loaded into thereceiver 28 and has a curved head for sliding, pivotal engagement with an inner surface of thereceiver 28. However, a variety of polyaxial connections may be possible. For example, a spline capture connection as described in U.S. Pat. No. 6,716,214, and incorporated by reference herein, may be used wherein the bone screw shank includes a capture structure mateable with a retaining structure disposed within the receiver. The retaining structure includes a partially spherical surface that is slidingly mateable with a cooperating inner surface of the receiver, allowing for a wide range of pivotal movement between theshank 27 and thereceiver 28. Polyaxial bone screws with other types of capture connections may also be used according to the invention, including but not limited to, threaded connections, frictional connections utilizing frusto-conical or polyhedral capture structures, integral top or downloadable shanks, and the like. Also, as indicated above, polyaxial and other bone screws for use with connecting members of the invention may have bone screw shanks that attach directly to the connecting member or may include compression members or inserts, such as themembers closure structure 32 of the present invention is illustrated with thepolyaxial bone screw 25 having an open receiver orhead 28, it foreseen that a variety of closure structures may be used in conjunction with any type of medical implant having an open or closed head or receiver, including monoaxial bone screws, hinged bone screws, hooks and the like used in spinal surgery. - To provide a biologically active interface with the bone, the threaded
shank 27 may be coated, perforated, made porous or otherwise treated. The treatment may include, but is not limited to a plasma spray coating or other type of coating of a metal or, for example, a calcium phosphate; or a roughening, perforation or indentation in the shank surface, such as by sputtering, sand blasting or acid etching, that allows for bony ingrowth or ongrowth. Certain metal coatings act as a scaffold for bone ingrowth. Bio-ceramic calcium phosphate coatings include, but are not limited to: alpha-tri-calcium phosphate and beta-tri-calcium phosphate (Ca3(PO4)2, tetra-calcium phosphate (Ca4P2O9), amorphous calcium phosphate and hydroxyapatite (Ca10(PO4)6(OH)2). Coating with hydroxyapatite, for example, is desirable as hydroxyapatite is chemically similar to bone with respect to mineral content and has been identified as being bioactive and thus not only supportive of bone ingrowth, but actively taking part in bone bonding. It is also foreseen that combinations of the above can be used, such as a composite of titanium plasma spray and hydroxyapatite. - The
closure structure 32 can be any of a variety of different types of closure structures for use in conjunction with the present invention with suitable mating structure on the interior surface of the upstanding arms of thereceiver 28. The illustratedclosure structure 27 is in two pieces with theouter fastener 33 rotatable between the spaced arms and theinner set screw 34 rotatable within theouter fastener 33. However, single piece closures may be used and other structures, such as slide-in closure structures may be used as an alternative to helically wound closures. The illustratedouter fastener 33 is substantially cylindrical and includes an outer helically wound guide and advancement structure in the form of a flange form that may take a variety of forms, including those described in Applicant's U.S. Pat. No. 6,726,689, which is incorporated herein by reference. It is also foreseen that according to the invention the closure structure guide and advancement structure could alternatively be a buttress thread, a square thread, a reverse angle thread or other thread like or non-thread like helically wound advancement structure for operably guiding under rotation and advancing the closure structure downward between the receiver arms and having such a nature as to resist splaying of the arms when the closure structure is advanced into the U-shaped channel formed by the arms. The illustratedclosure 32 further includes theinner set screw 34 with an internal drive in the form of an aperture utilized for assembly of the set screw and removal of theentire closure 32. It is foreseen that the closure structure may alternatively include an external drive, such as a break-off head designed to allow such a head to break from a base of the closure at a preselected torque, for example, 60 to 120 inch pounds. Such a closure structure would also include a base having an internal drive to be used for closure removal. - Returning to the longitudinal connecting
member assembly 1 illustrated inFIGS. 1-37 , theassembly 1 is elongate, with theinner core 6 being a substantially solid, smooth and in the form of a uniform cylinder or rod having an outercylindrical surface 36 and a substantially circular cross-section. Thecore 6 and integralanchor attachment portion 8 may be made from metal, metal alloys or other suitable materials, including plastic polymers such as polyetheretherketone (PEEK), ultra-high-molecular weight-polyethylene (UHMWP), polyurethanes and composites, including composites containing carbon fiber and layers of different materials. It is noted that although ananchor member 4 is illustrated in which thecomponents core 6 and theanchor attachment portion 8 may be made from different materials, for example, thecore 6 may be made out of PEEK and inserted into and fixed and/or adhered to a boneanchor attachment portion 8 made out of titanium. Thecore 6 andattachment portion 8 may include a small central lumen or through-bore (not shown) extending along the central axis A. Such a lumen may be used as a passage through theentire assembly 1 interior for a length of a guide wire for aiding insertion of theassembly 1 between implanted bone screws 25 in a percutaneous or less invasive procedure. - With particular reference to
FIGS. 3 and 5 , theanchor member 4 is substantially cylindrical along an entire length thereof along the axis A and includes at least two or more circular cross-sections along the length thereof. The illustratedmember 4 includes the slender and thus moreflexible core 6 of a first circular cross-section and the boneanchor attachment portion 8 that has a second circular cross-section that is larger than thecore 6 cross-section and thus is more rigid than thecore 6. Thecore 6 terminates at anend 38. Prior to final assembly by the vendor or manufacturer, thecore 6 is typically of a length greater than that shown in the drawing figures so that thecore 6 may be grasped by a tool (not shown) near theend 38 and pulled along the axis A in a direction away from theanchor attachment portion 8, in certain embodiments, tensioning thecore 6 and putting compressive forces on the spacers and bumper, as will be described in greater detail below. Between thecore 6 and theportion 8 is a buttress plate orannular enlargement 40 that has a third circular cross-section that is larger than theattachment portion 8 cross-section. The buttressplate 40 is integral with and disposed between thecore 6 and theportion 8. Although the illustratedanchor member 4 is substantially cylindrical, it is foreseen that thecore 6, theportion 8 and theplate 40 may have other forms, including but not limited to oval, square and rectangular cross-sections as well as other curved or polygonal shapes. The boneanchor attachment portion 8 is of a length along the axis A for cooperating with at least one and up to a plurality of bone attachment members, such as the bone screws 25, hooks or other types of bone anchors. Theportion 8 is substantially solid and rigid, with an outercylindrical surface 39 that terminates at anend 41. Theplate 40 includes a first substantially flat andannular face 42 facing away from thecore 6 and anopposed face 44 facing toward thecore 6. The faces 42 and 44 extend radially from the axis A. An outercylindrical surface 46 extends between thefaces flange 48 bridges between and connects the outercylindrical surface 36 of thecore 6 with the substantially flat facingface 44 of the buttressplate 40. - With particular reference to
FIGS. 13-15 and 19-22, thesleeves core 6 along the axis A and each have a length measured along the axis A that is sufficient for the attachment of at least onebone screw 25 thereon. Similar to theinelastic anchor member 4, theinelastic sleeves sleeves core 6, for example, theanchor member 4 and thesleeves core 6 may be made from one material, such as PEEK, while thesleeves sleeve core 6 outer surfaces may be coated with an ultra thin, ultra hard, ultra slick and ultra smooth coating, such as may be obtained from ion bonding techniques and/or other gas or chemical treatments. - The illustrated
sleeves outer surface 39 of the boneanchor attachment portion 8. Each of thesleeves inner surface core 6 therethrough. While thesurface 56 is shown as being cylindrical, the illustratedsurface 54 of thesleeve 12 is preferably curved and shown as slightly hour-glass or hyperboloid-like in configuration running along the axis A, and/or at least has non-linear relief at one or both ends. The slightlycurved surface 54 results in at least a partially non-linear inner lumen that decreases both bending stresses along thecore 6 and wear debris between the parts. For example, if thecore 6 is flexed, theinner surface 54 allows deformation of the core over a longer area or length resulting in reduced stresses and a longer fatigue life. Furthermore, if thecore 6 is made from a material such as PEEK, thecurved surface 54 and/or end surface non-linear relief reduces contact wear and bending stresses along thecore 6 surface that is received in thesleeve 12. Thesleeve 12 includes a pair ofopposed end plates sleeve 16 includes a pair ofopposed end plates plates cylindrical surfaces cylindrical surface 46. Thesleeve 12 includes opposed curved and slightly concave flanged end surfaces 70 and 72, each running from theinner surface 54 radially outwardly toward respectivecylindrical surfaces concave surfaces sleeve 16 includes oneconcave end surface 74 and an opposedplanar end surface 76. The illustratedsurface 74 is partially spherical. - With reference to
FIGS. 6-9 , 16-18 and 23-25, theelastic spacers elastic bumper 18 are sized and shaped to be slidingly received over thecore 6 and may be made from a variety of elastic materials of different durometers and materials, including, but not limited to natural or synthetic elastomers such as polyisoprene (natural rubber), and synthetic polymers, copolymers, and thermoplastic elastomers, for example, polyurethane elastomers such as polycarbonate-urethane elastomers. In order to have low or no wear debris, thespacers bumper 18 inner and side surfaces may also be coated with an ultra thin, ultra hard, ultra slick and ultra smooth coating, such as may be obtained from ion bonding techniques and/or other gas or chemical treatments. - The illustrated
spacers core 6 of theanchor member 4, providing directed axial movement, limitation and protection of movement by thesleeves core 6 located between bone screws 25. With particular reference toFIGS. 6-9 and 16-18, the illustratedspacers anchor member core 6 and number of optional outer grooves. Each of thespacers outer surface internal surfaces internal surface 82 is further defined by a flared or conical outwardly extendingsurface 86 sized and shaped for cooperating with thetransition surface 48 of theanchor member 4. Thespacer 10 includes opposed substantially planar and annular end surfaces 88 and 89 and thespacer 14 includes opposed substantially planar and annular end surfaces 90 and 91. When cooperating with thecore 6, the end surfaces 88 and 89 and 90 and 91 are substantially perpendicular to the axis A. It is foreseen that in some embodiments, thespacers spacers spacer 10 having asingle groove 93 and thespacer 14 having a pair ofgrooves spacers anchor attachment portion 8 and the cooperatingsleeves groove 93 andgroove pair external surfaces internal surfaces internal surfaces respective spacers core surface 36. The illustratedspacer 14 is more elastic than thespacer 10, both with respect to geometry, by having more grooves than thespacer 10 and also may be made from a material with greater elasticity (lower durometer) than thespacer 14, resulting in an assembly that advantageously provides for greater travel of the assembly in a cephalad direction, if desired. - With particular reference to
FIGS. 10-12 , the domed articulating wear orpressure washer 11 is shown. With reference toFIG. 3 , for example, it is noted that thepressure washers pressure washer 11, thus the discussion herein of thepressure washer 11 also applies to thewashers pressure washer 11 has an external substantially cylindricalouter surface 98 and internal substantiallycylindrical surface 100, defining a through bore sized and shaped to receive thecore 6. Thewasher 11 further includes a substantiallyplanar end surface 102 and an opposed, curved,convex surface 104 sized and shaped for cooperation with a substantially concave surface of a cooperating sleeve, such as thesurface 70,surface 72 or thesurface 74. The illustratedconvex surface 104 is at least partially spherical. When cooperating with thecore 6, theend surface 102 is substantially perpendicular to the axis A. The size of theinternal surface 100 allows for some axially directed sliding movement of thewasher 11 with respect to thecore surface 36. Thewasher 11 is preferably made from a firm material, such as metal and metal alloys with titanium being particularly preferred; or other suitable materials, including plastic polymers such as polyetheretherketone (PEEK), ultra-high-molecular weight-polyethylene (UHMWP), polyurethanes and composites, including composites containing carbon fiber. In order to reduce wear debris, thewashers sleeves sleeves washers washer 11 and as shown inFIG. 4 , with theconvex surface 104 slidingly engaging theconcave surface 72 of thesleeve 12, thepressure washer 11 advantageously allows for tilt, slide and rotation of the washers along thecore 6 and with respect to thesleeve 12, maintaining substantially full contact between thewasher 11 and thesleeve 12, resulting in better load distribution along theassembly 1, keeping stresses on the inside of thetubular sleeve 12, rather than on an outer surface or end, and thus allowing for better angulation, translation and compression of theentire assembly 1, as each of thepressure washers sleeves core 6, cooperatingcompressible spacers sleeves washers - The
over-molded coverings assembly 1 and keeping scar tissue out of theassembly 1 at the juncture between the spacers, washers and sleeves. Particularly when theassembly 1 is placed in tension as shown inFIG. 33 , theover-molded sections pressure washer 11 and thesleeve 12, guarding against gaps that might otherwise irritate scar and surrounding body tissue. Theover-molded sections - The illustrated
over-mold 22 is fabricated around and about thesurfaces anchor plate 40, theentire spacer 10, theentire washer 11 and theentire end plate 60 of thesleeve 12. The illustratedover-mold 23 is fabricated around and about the surfaces of theend plate 58 of thesleeve 12, theentire washer 13, theentire spacer 14, theentire washer 15 and theentire end plate 63 of thesleeve 16. The over-molds 22 and 23 are fabricated from an initially flowing elastomer, as will be described more fully below, with the elastomer engaging and possibly adhering to the surfaces of the sleeves, washers and spacers being covered thereby. Each formed elastomer is substantially cylindrical, but thin so as to also be flexible and deformable when theassembly 1 is bent, compressed or stretched as shown in the drawing figures. In both spinal flexion and extension, the over-molds 22 and 23 completely surround or cover theassembly 1 components as also illustrated in the drawing figures. It is foreseen that the material for the over-molds 22 and 23 may be sized and made from such materials so as to provide for relatively more or less bendability, as well as compressibility and stretchability. - With particular reference to
FIGS. 23-25 , theelastic bumper 18 is substantially cylindrical, including anouter surface 108 and aninner surface 109 forming a substantially cylindrical through bore that opens at planar end surfaces 110 and 111 and operatively extends along the axis A. Thebumper 18 may further include a compression groove or grooves similar in form and function to thecompression grooves spacers bumper 18 is sized and shaped to slidingly receive thecore 6 through theinner surface 109. Thebumper 18 is preferably made from an elastomeric material such as polyurethane, but may be made from any suitable elastomeric material. Thebumper 18 is typically more elastic than either of thespacers sleeve 16 in a direction toward thebumper 18 than toward thespacer 14. - With particular reference to
FIGS. 26-28 , the crimpingring 20 is substantially cylindrical and includes anouter surface 120 and aninner surface 122 forming a substantially cylindrical through bore that opens at planar end surfaces 124 and 126 and operatively extends along the axis A. The crimpingring 20 is sized and shaped to receive theelongate core 6 through theinner surface 122. The crimpingring 20 further includes a pair of opposed crimp orcompression grooves 130 that are pressable and deformable inwardly toward the axis A upon pre-compression of thespacers bumper 18 during assembly of theassembly 1. The crimpingring 20 is preferably made from a stiff, but deformable material, including metals and metal alloys. As an alternative to thegrooves 130, in certain embodiments of the invention, thecrimp ring 20 may include an inner helical thread (not shown) with thecore 6 having a mating helical outer thread (not shown), for fixing thering 20 on thecore 6 and compressing thespacers bumper 18 to a desired degree. - The illustrated dynamic connecting
member assembly 1 having pre-compressed spacers is shown cooperating with four polyaxial bone screws 25 as shown inFIG. 2 . In use, the bone screws 25 are implanted into vertebrae (not shown). Each vertebra may be pre-drilled to minimize stressing the bone. Furthermore, when a cannulated bone screw shank is utilized, each vertebra will have a guide wire or pin inserted therein that is shaped for the bone screw cannula of thebone screw shank 27 and provides a guide for the placement and angle of theshank 27 with respect to the cooperating vertebra. A further tap hole may be made and theshank 27 is then driven into the vertebra by rotation of a driving tool (not shown) that engages a driving feature on or near a top portion of theshank 27. It is foreseen that both thescrews 25 and the longitudinal connectingmember assembly 1 may be inserted in a conventional, percutaneous or other minimally invasive surgical manner. - With particular reference to
FIGS. 1-4 , the longitudinal connectingmember assembly 1 is assembled to providepre-compressed spacers bumper 18 prior to implanting theassembly 1 in a patient.FIGS. 1 , 2 and 4 illustrated the pre-compressed, ready to useassembly 1, whileFIG. 32 illustrates theassembly 1 during spinal movement that results in further compression of thespacers FIG. 33 illustrates theassembly 1 during spinal movement that results in further compression of thebumper 18 and extension of theassembly 1 at thespacers FIG. 3 , theassembly 1 is assembled by first providing theanchor member 4 that has acore 6 that is longer in the axial direction A than thecore 6 illustrated in the drawing figures. Thespacer 10 is first loaded onto thecore 6 by inserting thecore 6end 38 into the bore defined by theinner surface 82 with theface 89 directed toward the buttressplate 40. Thespacer 10 is moved along thecore 6 until thesurface 86 contacts thesurface 48. Thepressure washer 11 is then threaded on thecore 6 with theface 102 facing theend surface 88 of thespacer 10. Thesleeve 12 is then threaded onto thecore 6 with theconcave face 72 of theplate 60 facing theconvex surface 104 of thepressure washer 11. Thecore 6 is then received in the bore of thepressure washer 13, with the convex face of thewasher 13 facing theconcave face 70 of thesleeve 12. Thespacer 14 is thereafter loaded onto thecore 6 by inserting thecore 6end 38 into the bore defined by theinner surface 84 with theface 91 facing the toward thepressure washer 13. Thespacer 14 is moved along thecore 6 until thespacer 14 contacts thepressure washer 13. Thepressure washer 15 is then threaded on the core with a planar face thereof facing theplanar face 90 of thespacer 14. Thesleeve 16 is then threaded onto thecore 6 with theconcave face 74 facing the convex end surface of thepressure washer 15. Thecore 6 is received in the bore defined by the innercylindrical surface 56 and thesleeve 16 is moved along thecore 6 until thesleeve 16 abuts thepressure washer 15. Thebumper 18 is thereafter loaded onto thecore 6 by inserting thecore 6end 38 into the bore defined by theinner surface 109 with the face 111 facing the toward theplanar end surface 76 of thesleeve 16. Thebumper 18 is moved along thecore 6 until the surface 111 contacts thesurface 76. The crimpingring 20 is thereafter loaded onto thecore 6 by inserting thecore 6end 38 into the bore defined by theinner surface 122 with theface 126 facing the toward thesurface 110 of thebumper 18. The crimpingring 20 is moved along thecore 6 until thesurface 126 contacts thesurface 110. It is noted that due to the symmetrical nature of thesleeve 12, thespacer 14, thebumper 18 and the crimpingring 20, these components may be loaded onto thecore 6 from either side thereof. - After the crimping
ring 20 is loaded onto thecore 6, manipulation tools (not shown) are used to grasp thecore 6 near theend 38 and at the boneanchor attachment portion 8, placing some tension on thecore 6. Thespacer 10, thesleeve 12, thespacer 14, thesleeve 16, thebumper 18 and the crimpingring 20 are moved toward the buttressplate 40 and into contact with one another. A desired amount of axial compressive force is placed on the components loaded on thecore 6, followed by deforming the crimping ring at thecrimp grooves 120 and against thecore 6. When the manipulation tools are released, the crimpingring 20, now firmly and fixedly attached to thecore 6 holds thespacers bumper 18 in compression and the spacers and bumper place axial tension forces on thecore 6, resulting in a dynamic relationship between thecore 6 and thespacers bumper 18. Thespacers core 6, but also are limited by the buttress plate of theanchor member 4 and end plates of thesleeves bumper 18 that is compressed between thesleeve surface 76 and the crimping ring surface 116 is also slidable with respect to thecore 6. Thespacers bumper 18 place a distractive force on thecore 6 along the axis A and between the buttressplate 40 and the crimpingring 20, but also are movable with respect to thecore 6, thus being able to respond to jolting and other body movements and thereafter spring back into an originally set location. Thesleeves spacers spacers spacers core 6 in response to outside forces. Thecore 6 is then trimmed to be approximately flush with the end surface 114 of the crimpingring 20. - It is noted that mechanical characteristics of the assembly components, such as creep, may require the
spacers bumper 18 to be compressed at a higher load and then allowed to reach a steady state before placement and molding of theover-mold coverings anchor portion 8 and/or thesleeves such portion 8 and/orsleeves plate 40, thespacer 10, thepressure washer 11 and an end portion of thesleeve 12 and the over-mold 23 about and between an opposite end portion of thesleeve 12, thewasher 13, thespacer 14, thewasher 15 and an end portion of thesleeve 16 as best shown in phantom inFIG. 4 . In a preferred method of fabrication of the over-molds 22 and 23, an elastic, polymeric material flows about the desired components of theassembly 1 at room temperature, followed by a vacuum cure. It is noted that in some embodiments of the invention, the over-molds 22 and 23 may be fabricated about the desiredassembly 1 components prior to compression of thespacers bumper 18. In other embodiments, the over-molds 22 and 23 may be fabricated about thespacers - With reference to FIGS. 2 and 29-37, the
assembly 1 is eventually positioned in an open or percutaneous manner in cooperation with the bone screws 25 with the over-molds 22 and 23 disposed between bone screws 25, with a bone screw attached to each of thesleeves bone screws 25 attached to theanchor portion 8. Aclosure structure 32 is used to attach eachscrew 25 to theassembly 1 with thesleeves anchor portion 8 each being cradled between alower pressure insert 29 and anupper pressure insert 30. - With particular reference to
FIGS. 2 , 32-33, a desired placement of theassembly 1 is shown wherein an arrow C indicates movement of the bone screws 25 attached to thesleeves FIG. 2 illustrated apre-compressed assembly 1 in a neutral position,FIG. 32 illustrates compression of thespacers FIG. 33 shows extension or tension of the assembly atspacers sleeves FIGS. 32-33 illustrate how theassembly 1 allows greater movement of the sleeves and thus the bone screws 25 and attached spinal segments in the cephalad direction than in the caudad direction, theelastic bumper 18 being the most compressible component of theassembly 1 and thespacer 14 being more elastic and thus more compressible than thespacer 10 due to the geometry thereof (e.g., an extra groove in the spacer 14). In other embodiments of the invention, thespacer 14 may be made from a material of different durometer than thespacer 10, to allow for a desirable increased upward or cephalad movement of a portion of theassembly 10. - With reference to
FIGS. 34 and 35 , supported spinal extension as well as movement in the cephalad direction C is also possible with theassembly 1. Thewashers sleeves washers sleeves spacers assembly 1, supporting and controlling the spine in response to lordosis and kyphosis, for example, and also providing for rotation and tilting of the assembly in both coronal and sagittal planes, supporting and controlling the spine in the case of scoliosis as shown inFIGS. 36 and 37 . Thus, once attached to the bone screws 25, theassembly 1 is substantially dynamically loaded and oriented relative to the cooperating vertebra, providing relief (e.g., shock absorption) and protected movement with respect to not pnly flexion and extension, but also to distractive, compressive, torsional and shear forces placed onassembly 1 and bone screws 25. - If removal of the
assembly 1 from any of thebone screw assemblies 25 is necessary, or if it is desired to release theassembly 1 at a particular location, disassembly is accomplished by using a driving tool (not shown) with a driving formation cooperating with theclosure structure 32 to rotate and remove the closure structure from thereceiver 28. Disassembly is then accomplished in reverse order to the procedure described previously herein for assembly. - Eventually, if the spine requires more rigid support, the connecting
member assembly 1 according to the invention may be removed and replaced with another longitudinal connecting member, such as a solid rod, having the same diameter as therod portions 8, utilizing thesame bone screw 25 components. Alternatively, if less support is eventually required, a less rigid, more flexible assembly, for example, anassembly 1 made with elastic spacers and bumper of different durometer or geometry may replace theassembly 1, also utilizing the same bone screws 25. - With reference to
FIGS. 38-44 , an alternative embodiment of a dynamic longitudinal connecting member, generally 201 is substantially similar to theassembly 1 with the exception that it is shorter than theassembly 1, cooperating with fewer bone screws along an elastic and more flexible portion thereof. Similar to theassembly 1, theassembly 201 provides for greater movement in the cephalad direction as indicated by the arrow marked CC. Theassembly 201 includes an anchor member, generally 204, having an elongate segment orinner core 206 and a boneanchor attachment portion 208; anelastic spacer 210; apressure washer 211; asleeve 216; anelastic bumper 218; and a crimpingring 220; all substantially symmetrically aligned with respect to a central axis AA of theanchor member 204. Theelongate core 206 of theanchor member 204 is receivable within thespacer 210, thewasher 211, thesleeve 216, thebumper 218 and the crimpingring 220. Thus, the axis AA of theanchor member 204 is also the axis of the fully assembledassembly 201. When fully assembled and fixed with all components fixed in position, thespacer 210 and thebumper 218 are placed in compression as shown inFIG. 40 and an elastic over-mold or covering 222 is applied about a buttressplate 240 of theanchor 204, thespacer 210, thewasher 211 and a portion of the sleeve 212 (the covering 222 shown in phantom inFIG. 40 ) prior to attachment to threebone screws 25 as shown inFIG. 38 . - In the illustrated embodiment, the
anchor member 204 is substantially similar to theanchor member 4 previously described herein with respect to theassembly 1. Therefore, themember 204 includes thecore 206, the boneanchor attachment portion 208 and the integral buttressplate 240 identical or substantially similar in size and shape to therespective core 6,attachment portion 8 and buttressplate 40 of theanchor member 4 previously described herein. Themember 204 differs from themember 4 only in that the length of thecore 206 is shorter than thecore 6 as thecore 206 holds only onesleeve 216, one cooperatingspacer 210 and onewasher 211 as compared to thecore 6 that holds two sleeves, two spacers and three cooperating washers. Thespacer 210 is identical or substantially similar to thespacer 10 previously described herein. Thesleeve 216 is identical or substantially similar to thesleeve 16, having aconcave end surface 274 identical or substantially similar to theconcave end surface 74 of thesleeve 16 previously described herein. Thewasher 211 is identical or substantially similar to thewasher 11 previously described herein, having a substantiallyconvex end surface 304 identical or substantially similar to theend surface 104 os thewasher 11. Thesurface 304 is slidably engageable with theconcave surface 274 of thesleeve 216 such that a full and even surface contact occurs between thesleeve 216 and thewasher 211, providing better load distribution along theassembly 201, keeping stresses on the inside of thesleeve 216 rather than on an outer surface during angulation, translation and compression. Thebumper 218 and the crimpingring 220 are identical or substantially similar to therespective bumper 18 and the crimpingring 20 previously described herein with respect to theassembly 1. - The
assembly 201 is assembled in a manner substantially similar to the manner of assembly previously described herein with respect to theassembly 1, theassembly 201 however, does not include a second spacer or second sleeve. Therefore, thecore 206 is first received within a through bore of thespacer 210, followed by thewasher 211, then within an inner surface of thesleeve 216, followed by an inner through bore of thebumper 218 and then an inner through bore of the crimpingring 220. Similar to what has been described previously with respect to theassembly 1, thecore 206 may initially be of a longer length measured along the axis AA than is shown in the drawing figures, allowing for a manipulation tool to grasp thecore 206 near an end thereof that extends through the crimping ring bore. Thespacer 210 andbumper 220 are compressed, followed by deformation of the crimpingring 220 against thecore 206. Then, the covering 222 is fabricated about theplate 240, thespacer 210, thewasher 211 and an end portion of thesleeve 216. The assembly is now in dynamic relationship with thespacer 210,washer 211,sleeve 216 andbumper 218 being slidable with respect to thecore 206, thesleeve 216 being more readily movable in a direction toward thebumper 218 due to the greater elasticity of thebumper 218 as compared to thespacer 210. - The
assembly 201 may then be implanted, cooperating with threebone screws 25 as illustrated inFIG. 38 and as previously described herein with respect to theassembly 1. Unlike theassembly 1 that provides for a more dynamic and flexible connection between three illustrated bone screws 25, theassembly 201 provides for dynamic stabilization between first and second bone screws 25 and a more rigid connection between thesecond bone screw 25 and athird bone screw 25 as both the second and third bone screws are attached to therigid attachment portion 208. -
FIGS. 41 and 42 illustrate a range of axial or spinal movement of the assembly in a cephalad direction as noted by the arrow CC.FIG. 41 shows thespacer 210 being compressed and thus thesleeve 216 and attachedbone screw 25 moving in a caudal direction.FIG. 42 shows thebumper 218 in a fully compressed state with thesleeve 216 and attachedbone screw 25 moving in a cephalad direction. As illustrated inFIG. 42 , theoptional over-mold 222 covers the portion of theassembly 201 that is being stretched and tensioned, covering a gap formed between thesleeve 216 and thepressure washer 211, protecting spinal tissue and retaining any wear debris within theassembly 201. - With reference to
FIG. 43 , theassembly 201 is shown in an angulated or bent position as it would be in response to spinal extension, for example. The load on theassembly 201 being stabilized by movement of thepressure washer 211 with respect to thesleeve 216 and also by partial compression of thespacer 210 along a groove thereof. - With reference to
FIG. 44 , theassembly 201 is shown in an angulated or bent position as it would be in response to spinal flexion, for example. The load on theassembly 201 is also distractive, causing a gap between thesleeve 216 and thepressure washer 211. The over-mold 222 advantageously stretches and prevents tissue from entering into the gap between thesleeve 216 and thewasher 211. - With reference to
FIGS. 45-47 , an alternative embodiment of a dynamic longitudinal connecting member, generally 301 is substantially similar to theassembly 1 with the exception of some aspects of the geometry of the sleeve or tube trolley members, one of the spacers and two of the pressure washers located on either side of such spacer. Similar to theassembly 1, theassembly 301 provides for greater movement in the cephalad direction as indicated by the arrow marked CCC. Theassembly 301 includes an anchor member, generally 304, having an elongate segment orinner core 306 and a boneanchor attachment portion 308;elastic spacers pressure washers tube trolleys elastic bumper 318; and a crimpingring 320, all substantially symmetrically aligned with respect to a central axis AAA of theanchor member 304. Theelongate core 306 of theanchor member 304 is receivable within thespacers washers sleeves bumper 318 and the crimpingring 320. Thus, the axis AAA of theanchor member 304 is also the axis of the fully assembledassembly 301. When fully assembled and fixed with all components fixed in position, thespacers bumper 318 are placed in compression as shown inFIG. 45 and an optional elastic over-mold or covering 322 is applied about a buttressplate 340 of theanchor 304, thespacer 310, thewasher 311 and a portion of thesleeve 312 and an optional elastic over-mold or covering 323 is applied about a portion of thesleeve 312, thewasher 313, thespacer 314, thewasher 315 and a portion of thesleeve 316, bothover-molds assembly 310 to three bone anchors such as the bone screws 25, in the same positions shown for theassembly 1 inFIG. 32 , for example. - The
anchor member 304, thespacer 310, thepressure washer 311, thesleeve 312, thebumper 318 and the crimpingring 320 are identical or substantially similar to therespective anchor member 4,spacer 10,pressure washer 11,sleeve 12,bumper 18 and crimpingring 20 of theassembly 1 and therefore shall not be discussed in great detail herein. Thesleeve 312 has a curvedinner surface 354 substantially similar to the curvedinner surface 54 previously described herein with respect to thesleeve 12. Thesleeve 316 has a curved inner surface 355 that is also substantially similar to the curvedinner surface 54 previously described herein with respect to thesleeve 12. In substantially all other aspects of form and function, thesleeve 316 is substantially similar to thesleeve 16 previously described herein with respect to theassembly 1. Thesleeve 312 includes a pair ofopposed end plates sleeve 316 includes a pair ofopposed end plates plates cylindrical surfaces spacer 314 and thewashers sleeves adjacent washers - Thus, the
assembly 301 primarily differs from theassembly 1 in the geometry of thewashers spacer 314. Theelastic spacer 314 is substantially similar to thespacer 14 in form, function and materials with the exception that rather than having opposed planar side surfaces 90 and 91, thespacer 314 has opposed side surfaces 390 and 391 that are curved and concave. In particular, the illustratedsurfaces washers spacer 314 and thewashers spacer 314. - The
pressure washers pressure washer 11 previously described above with the exception that thewashers sleeve 312 or theconcave surfaces spacer 314. The illustratedwasher 313 has opposedcurved surfaces washer 315 has opposedcurved surfaces 402′ and 404′. - The
assembly 301 is assembled in a manner substantially similar to the manner of assembly previously described herein with respect to theassembly 1. Also, similar to what has been described previously with respect to theassembly 1, thecore 306 may initially be of a longer length measured along the axis AAA than is shown in the drawing figures, allowing for a manipulation tool to grasp thecore 306 near an end thereof that extends through the crimping ring bore. Thespacers bumper 318 are compressed, followed by deformation of the crimpingring 320 against thecore 306. Then, thecoverings assembly 301 at the locations shown in the figures and as described above. Theassembly 301 is now in dynamic relationship with thespacers washers sleeves bumper 318 being slidable with respect to thecore 306, bothsleeves bumper 318 due to the greater elasticity of thebumper 318 as compared to thespacers - The
assembly 301 may then be implanted, cooperating with threebone screws 25 as previously illustrated with respect to theassembly 1. Like theassembly 1, theassembly 301 provides for a dynamic and flexible connection between three bone anchors. Furthermore, the double domed articulatingwear washers cupped spacer 314 allow for increased flexion and extension over theassembly 1 having thespacer 14 with planar surfaces. While theassembly 1spacer 14, for example, elastically compresses when the assembly bends during spinal flexion or extension, thepressure washers surfaces spacer 314 during spinal flexion or extension. If compression accompanies the bending movement, thespacer 314 may also compress slightly in response to the spinal movement. As illustrated in FIG. 47, theend plates sleeve 312 and theend plates sleeve 316 are sized and shaped to have a smaller outer diameter than the pressure washers and spacers of theassembly 301 as well as provide a gap between such plates and adjacent components of theassembly 301, providing clearance for articulated movement between the components. - It is to be understood that while certain forms of the present invention have been illustrated and described herein, it is not to be limited to the specific forms or arrangement of parts described and shown.
