Description
STABILIZING DEVICE FOR INTERVERTEBRAL DISC, AND METHODS
THEREOF
Background of the Invention Field of the Invention This invention pertains to surgical stabilizing devices and procedures for stabilizing joints within the spine, and other joints. More particularly, this invention peutains to a novel stabilizing device that utilizes one or more local bone autografts harvested during the implantation procedure.
Description of the Related Art The treatment of back pain can be relieved by preventing relative motion between spinal vertebrae. Intervertebral stabilization achieved by the use of spine cages, intervertebral spacers, and bone grafts for insertion into the space formerly occupied by a degenerated disc are known in the art. These devices may involve mechanically coupling the adjacent vertebrae or by promoting fusion between them. Accordingly, such techniques axe used to stabilize the spine and reduce pain by rigidly joining two adjacent vertebrae that oppose a degenerated disc or degenerated posterior elements of the vertebrae (e.g. facetjoints).
Summary of the Invention In one embodiment of the current invention, an implantable stabilizing device for stabilizing two adj acent vertebral bodies in the human spine is provided. The stabilizing device, or implant, comprises an elongated body, having a longitudinal axis and a transverse axis, and at least two bone cutting surfaces. In one embodiment, the elongated body has a first bone cutting surface and a second bone cutting surface that are offset from the longitudinal axis of the body. The first bone cutting surface faces in a first direction, and the second bone cutting surface faces in a second direction. The first bone cutting surface and/or the second bone cutting surface is adapted to cut bone upon rotation of the body about its longitudinal axis between two adjacent vertebral bodies.
In several embodiments, the bone cutting surfaces are blades or blade-like surfaces.
In one embodiment, the first bone cutting surface, the second bone cutting surface and/or the elongated body has one or more perforations, holes, or voids. In another embodiment, .
the first bone cutting surface, the second bone cutting surface and/or the elongated body is made of a material that is at least partially porous.
In one embodiment, at least a portion of the elongated body is hollow. In some embodiments, the elongated body is a support member that serves to comlect two bone cutting blades.
In one embodiment, at least one bone cutting surface comprises one or more teeth.
In another embodiment, at least one bone cutting surface is curved inward relative to the elongated body. In one embodiment, at least one bone cutting surface is sharpened. In another embodiment, at least one bone cutting surface is blunt.
hl several embodiments, a portion of a bone cutting surface and/or the elongated body includes at least one shearing means or protrusions. Protrusions include, but are not limited to, barbs, spires and wedges. In some embodiments, a portion of a bone cutting surface and/or the elongated body is treated with a surface treatment. The surface treatment includes, but is not limited to, bone growth facilitator (e.g., bone morphogenic protein) and/or adhesives (e.g., cyanoacrylate). In one embodiment, the implantable stabilizing device further includes a source or supply of bone growth facilitator.
In several embodiments, a portion of a bone cutting surface and/or the elongated body is constructed from a biocompatible material, including but not limited to titanium, steel, plastic, and ceramic.
In one embodiment of the present invention, an implantable device for stabilizing a joint is provided. W one embodiment, the joint is a spinal joint. In other embodiments, the joint is in the shoulder, wrist, anrle, knee, hip, or digits. In several embodiments, the implantable device, or implant, comprises a first bone cutting surface and a second bone cutting surface that are connected by a support member.
In one embodiment, the bone cutting surfaces include a first leading edge, a first trailing edge, a first top edge and a first bottom edge. The support member comprises a length that is mounted perpendicular to the first bone cutting surface and the second bone cutting surface and is spaced from said first bone cutting surface and second bone cutting surface by a distance in the range of about 1 cm to about 5 cm. At least one of the bone cutting surfaces is adapted to accept a local bone autograft.
In one embodiment, at least one of bone cutting surface is a blade. hi another embodiment, at least one of bone cutting surface is a blade is curved inward relative to the support member.

Intervertebral stabilization achieved by the use of spine cages, intervertebral spacers, and bone grafts for insertion into the space formerly occupied by a degenerated disc are known in the art. These devices may involve mechanically coupling the adjacent vertebrae or by promoting fusion between them. Accordingly, such techniques axe used to stabilize the spine and reduce pain by rigidly joining two adjacent vertebrae that oppose a degenerated disc or degenerated posterior elements of the vertebrae (e.g. facetjoints).

Detailed Description of the Preferred Embodiment Several embodiments of present invention involve stabilizing devices and methods that immobilize adjacent vertebral bodies or other selected joints. One or more of the embodiments, a stabilizing device, or implant, is provided to re-establish and maintain proper alignment and distance between the adjacent vertebrae and to serve as a spacer or fusion cage. The shape of the stabilizing device offers sufficient surface area to offer initial resistance to axial compression between the adjacent end plates and over time, as fusion progresses, even greater resistance. Several embodiments of the present invention are particularly advantageous because they offer pain relief. In one embodiment, pain caused by spinal stenosis or by degenerated or herniated disc tissue is ameliorated or eliminated via discectomy and reestablishment of proper vertebral spacing. In another embodiment, pain caused by degenerated facet joints and pathological increased range of motion is reduced.
In one embodiment, the methods of autograft bone harvest and implantation are combined. Here large hunts or plates (as compared to small chips) are cleaved from a proximal bony surface as the stabilizing device is inserted between the vertebral bodies.
Large chunl~s of bone with sufficient surface area and structural integrity are harvested.
The site in which one or more of the grafts are harvested axe also "prepared"
in that the bone surface is scraped, or otherwise manipulated, to stimulate a healing response and promote fusion. By selecting local bone (and not bone from, for example the hip which requires addition incisions and site preparation and closing) and combing the harvesting step with the implantation step, several embodiments of the invention provide several benefits. These benefits include, but are not limited to, decreased operation time, increased surgical efficiency, patient acceptance of the stabilizing device, and effectiveness of the fusion. Although, in a preferred embodiment large portions of local bone axe cleaved, one of shill in the art will understand that smaller bone fragments and/or non-local bone from other sites can be used in accordance with several embodiments of the present invention.

Alternatively the bone cutting surfaces could simply be connected by one or more struts or support members instead of the elongated body. Each bone cutting surface can have four sharpened edges or portions sharpened thereof such on or more of the leading, trailing, and horizontal edges of the bone cutting surfaces. In several embodiments, the first bone cutting surfaces 14 and/or the second bone cutting surfaces 16 is comprised of a plurality of bone cutting surfaces.

FIG. 5 is an isometric view of one embodiment of the invention showing an elongated body with a first bone cutting surface 116 and second bone cutting surface 118.
The body 114 is at least partially hollow. In one embodiment, the hollowed portion is adapted to accept graft material or other biocompatible material. In one embodiment, the hollow body facilitates rotation of the stabilizing device. In embodiments where the body is not hollow, a hex-shaped insert may be cut-out of the body to facilitate rotation with compatible rods and tools. In some embodiments, the elongated body is a support member that serves to connect two bone cutting surfaces.
In one embodiment, a portion of a bone cutting surface and/or the elongated body includes at least one shearing means or protrusion. Protrusions include, but are not limited to, barbs, spikes and wedges. In some embodiments, a portion of a bone cutting surface and/or the elongated body is treated with a surface treatment, such as bone growth facilitator (e.g., bone morphogenic protein) and/or adhesives (e.g., cyanoacrylate). In one embodiment, the implantable stabilizing device further includes a source or supply of bone growth facilitator. Bone growth facilitator aids in the promotion of bone growth and/or stability and, in some embodiments, can accelerate bone fusion and decrease patient recovery times.
FIG. 6 shows a hollow elongated body 214, comprising one or more perforations, holes, or voids. The first bone cutting surface 216 and/or the second bone cutting surface 218 also comprises one or more perforations, holes, or voids. One function of the perforations, holes, or voids is to permit bone ingrowth and promote fusions.
In one embodiment, at least one of the cutting surfaces or the body is at least partially porous. The porous material, and the perforations, holes, or voids, are also advantageous because they permit the infusion or passage of bone growth facilitator to the required sites.
FIG. 7 expands on the concept depicted in FIG. 6 by removing substantially all of the elongated body to leave a body 314 comprising of a leading support member 328 and trailing support member 330, shown here with rectangular voids. One of skill in the art will understand that the voids can be of any shape suitable to accomplish the desired purpose, including, but not limited to, rectangular, square, triangular, oval or circular-shaped voids.
In one embodiment, the first bone cutting surface 316 and/or the second bone cutting surface 318 have sharpened horizontal edges 20', 20" and can be rotated up to 360 degrees and serve to scoop, bore or core out an entire graft segment, or portions thereof. In another method, the device 500 can be rotated in the range of about 90 degrees to about 180 degrees.
FIG 8 shows one embodiment of the device with the first bone cutting surface and second bone cutting surface 418 comprising one or more voids in the body 414 and/or bone cutting surfaces 416, 418. In one embodiment, two or more voids along the horizontal edges 20', 20" create teeth 432, 434. In one embodiment, each bone cutting surface 416, 418 has a horizontal edge 20 with leading 432', trailing upper teeth 432", and leading 434' and trailing 434" lower teeth. One skilled in the art will understand that fewer or more teeth can be used in accordance with several embodiments of the present invention.
FIG. 9 shows a side view of one embodiment of the stabilizing device 500 coupled to a driver 550. The stabilizing device, or implant, comprises a leading edge 510 and a horizontal edge 520. The coupling, engagement or connection can be a socket and sleeve, friction fit, clamp, or other connection known in the art. The driver 550 can be used as a site to apply the force of a haxmner, or other like tool, to cut through the vertebrae of a herniated spine unit 200 and later as a site to apply rotational force 510 by hand or machine.
According to several embodiments of the invention, the stabilizing device 500 can be a uni-or muhti-component construct of biocompatible material. For example the entire stabilizing device 500, or portions thereof, could be constructed from titanium or steel, or some combination thereof. Alternatively, other metals and alloys could be employed for the bone cutting surfaces and coupled to plastic, ceramic, or other biocompatible material comprising the connection member or elongated body. Accordingly, various embodiments of the invention can be constructed from ceramics, metals, plastics, composites or any suitable biocompatible material and combinations thereof.
As discussed above, in several embodiments, various sharpened and blunt protrusions along the length and faces of the bone cutting surfaces and off of the central body of the stabilizing device can be used for shearing and cutting. For example, the sharpened protrusions on the leading edge of the bone cutting surfaces can be used to facilitate straight shearing or cutting as the stabilizing device is hammered in place prior to the rotational shearing by the blunt or sharpened horizontal edge. The shape of the bone cutting surface and its orientation with respect to the elongated body or connection members can be adapted to hold or keep harvested autograft in place by angling the bone cutting surfaces less than 90 degrees relative to the body or by curving them in ward. Barbs _g_ or surface roughness along the bone cutting surfaces and body may also be used to fix the graft to the stabilizing device.
Dimezzsiozzs azzd Size Razzge In several embodiments, the stabilizing device can be properly sized from precise dimensions of the intervertebral disc geometry of the individual selected for treatment. One skilled in the art will understand that these dimensions can be culled from CAT scan data or similar data from another modality. For example, scans can be used to determine the proper or normal distance between adjacent vertebral bodies and this distance can be used to approximate the height of the stabilizing device. Similarly, data from scans depicting the internal dimensions of the anulus and endplates (in a neutral position) can be used to design the outer shape of the device so that after harvesting bone along the endplates and rotating the stabilizing device, a precise fit is achieved. In one embodiment, the device has a width in the range of about .25 cm to about 7 cm, preferably between about .5 cm to about 6 cm, more preferably between about 1 cm to about 5 cm. In one embodiment, the device has a length in the range of about .25 cm to about 5 cm, preferably between about .5 cm to about 4 cm, more preferably between about 1 cm to about 3 cm. In one embodiment, multiple stabilizing devices are stacked between the same two vertebral bodies. Such stacking, in some embodiments, aid in stability and allow for the use of smaller stabilizing devices.
Delivery Method In one embodiment of the present invention, a method of initiating bony fusion between a first bone and a second bone is provided. In one embodiment, an implant having a body with a longitudinal axis, and at least a first bone cutter and a second bone cutter offset in opposite transverse directions from the longitudinal axis is provided. The implant is introduced between the first and second bones and rotated about its longitudinal axis so that the first and second bone cutters cut fragments from the first and second bones. The implant is left in position between the first and second bones. In some embodiments, a second implant is inserted in between the first and second bones. In one embodiment, bony fusion is initiated between adjacent vertebral bodies. In one embodiment, at least one of the first and second vertebral bodies is in the sacral spine, lumbar spine or cervical spine. In one embodiment, the implant is rotated through no more than one revolution. In another embodiment, the implant is rotated through no more than about 120 degrees. In another embodiment, rotation is stopped at a point where the first bone cutter is in contact with the first bone and the second bone cutter is in contact with the second bone.
In one embodiment, bone growth facilitator is infused through at least a portion of the implant. Bone growth facilitator can be introduced via one or more lumens in the boring instrument or rods, described below, or can be introduced using a separate insertion device. In one embodiment, bone growth facilitator is an integral part of the stabilizing device. In some embodiments, the stabilizing device, or implant, is coupled to a source of bone growth facilitator. W alternative embodiments, the implant is pre-treated with bone growth facilitator.
In several embodiments, more than one stabilizing device is used. In one embodiment, two stabilizing devices are used. In another embodiment, three stabilizing devices are used. In one embodiment, a stabilizing device as described herein is used in connection with one or more structural devices, such as screws, that are used to stabilize the space between two bones by restricting movement.
In one embodiment, insertion of the stabilizing device is performed using an anterior approach, though a lateral approach can also be used. FIG. 10 shows an isometric view of the posterior of a functional spinal unit 100 comprising a superior vertebral body 1, inferior vertebral body 2, an anulus 3, a transverse process 4, and portion of a facet joint 6.
The other posterior elements have been surgically removed. In this embodiment, a posterior approach can be used.
In one embodiment, arthroscopic equipment l~nown in the art may be used to perform a partial or complete discectomy to provide an initial implantation site. A
distraction device can then be used to provide access to the intervertebral space and allow for precise delivery. Alternatively, the stabilizing device itself can be designed with a wedge profile and forcibly inserted across the endplates thereby distracting them. An insertion rod can engage or be placed against the distal or trailing side if the device and used to push the device or as a site to apply the force of a hammer.
In a~i alternative delivery method, the stabilizing device can be used without performing a discectomy or distracting the endplates. In this embodiment, the leading edges of the bone cutting surfaces of the stabilizing device are also sharpened and used to cut straight into the vertebral bodies (across to the endplates) as the stabilizing device is driven between and parallel the adjacent endplates. As the stabilizing device is inserted, a hollow mid-section of the central body can accept the displaced disc material in between.
FIGS. 11A-C show a method of delivery according to one embodiment of the invention. Following the initial implantation between the vertebral bodies 7, 8, one or more drivers 550 or insertion rods are engaged to the device and used to impart axial rotation (driver is not shown) causing the bladed edges of the stabilizing device along its length to gouge and shear off portions of the adjacent endplates 7, 8. These portions are then forced into the adjacent hollow receiving zones of the stabilizing device. Barbs or other means, including, but not limited to spikes, wedges, surface treatments, adhesives (e.g., cyanoacrylate) or some combination thereof, may be used along the stabilizing device surface, or portions of the stabilizing device surface, to retain the harvested bone 600.
After rotation through approximately 90 degrees, the driver 550 or insertion rod is removed. In this orientation, the harvested bone 600 contacts the sidewalls and edges of both vertebrae that now have freshly scraped osteogenic surfaces. The curved and sharpened edges of the stabilizing device lie substantially parallel to the endplates and the harvested bone is flush with or extends beyond their edges to reduce or prevent further cutting or physical trauma. hl one embodiment, a hollow stabilizing device (as shown in FIG. 7) is used to fully shear through the bone in one or more partial or complete revolutions.
FIG. 12A and 12B show an alternative delivery method in which an initial step is added prior to inserting the stabilizing device. Here one or more horizontal holes or slots 905 are punched above each of the endplates as shown. The stabilizing device 500 is hammered into place through the endplates and across the disc space. One advantage of this step is that it facilitates rotation of the stabilizing device 500 (and displacement of the bone grafts).

In one embodiment, a portion of a bone cutting surface and/or the elongated body includes at least one shearing means or protrusion. Protrusions include, but are not limited to, barbs, spikes and wedges. In some embodiments, a portion of a bone cutting surface and/or the elongated body is treated with a surface treatment, such as bone growth facilitator (e.g., bone morphogenic protein) and/or adhesives (e.g., cyanoacrylate). In one embodiment, the implantable stabilizing device further includes a source or supply of bone growth facilitator. Bone growth facilitator aids in the promotion of bone growth and/or stability and, in some embodiments, can accelerate bone fusion and decrease patient recovery times.
FIG. 6 shows a hollow elongated body 214, comprising one or more perforations, holes, or voids. The first bone cutting surface 216 and/or the second bone cutting surface 218 also comprises one or more perforations, holes, or voids. One function of the perforations, holes, or voids is to permit bone ingrowth and promote fusions.
In one embodiment, at least one of the cutting surfaces or the body is at least partially porous. The porous material, and the perforations, holes, or voids, are also advantageous because they permit the infusion or passage of bone growth facilitator to the required sites.
FIG. 7 expands on the concept depicted in FIG. 6 by removing substantially all of the elongated body to leave a body 314 comprising of a leading support member 328 and trailing support member 330, shown here with rectangular voids. One of skill in the art will understand that the voids can be of any shape suitable to accomplish the desired purpose, including, but not limited to, rectangular, square, triangular, oval or circular-shaped voids.
In one embodiment, the first bone cutting surface 316 and/or the second bone cutting surface 318 have sharpened horizontal edges 20', 20" and can be rotated up to 360 degrees and serve to scoop, bore or core out an entire graft segment, or portions thereof. In another method, the device 500 can be rotated in the range of about 90 degrees to about 180 degrees.
FIG 8 shows one embodiment of the device with the first bone cutting surface and second bone cutting surface 418 comprising one or more voids in the body 414 and/or bone cutting surfaces 416, 418. In one embodiment, two or more voids along the horizontal edges 20', 20" create teeth 432, 434. In one embodiment, each bone cutting surface 416, 418 has a horizontal edge 20 with leading 432', trailing upper teeth 432", and leading 434' and trailing 434" lower teeth. One skilled in the art will understand that fewer or more teeth can be used in accordance with several embodiments of the present invention.
FIG. 9 shows a side view of one embodiment of the stabilizing device 500 coupled to a driver 550. The stabilizing device, or implant, comprises a leading edge 510 and a horizontal edge 520. The coupling, engagement or connection can be a socket and sleeve, friction fit, clamp, or other connection known in the art. The driver 550 can be used as a site to apply the force of a haxmner, or other like tool, to cut through the vertebrae of a herniated spine unit 200 and later as a site to apply rotational force 510 by hand or machine.
According to several embodiments of the invention, the stabilizing device 500 can be a uni-or muhti-component construct of biocompatible material. For example the entire stabilizing device 500, or portions thereof, could be constructed from titanium or steel, or some combination thereof. Alternatively, other metals and alloys could be employed for the bone cutting surfaces and coupled to plastic, ceramic, or other biocompatible material comprising the connection member or elongated body. Accordingly, various embodiments of the invention can be constructed from ceramics, metals, plastics, composites or any suitable biocompatible material and combinations thereof.
As discussed above, in several embodiments, various sharpened and blunt protrusions along the length and faces of the bone cutting surfaces and off of the central body of the stabilizing device can be used for shearing and cutting. For example, the sharpened protrusions on the leading edge of the bone cutting surfaces can be used to facilitate straight shearing or cutting as the stabilizing device is hammered in place prior to the rotational shearing by the blunt or sharpened horizontal edge. The shape of the bone cutting surface and its orientation with respect to the elongated body or connection members can be adapted to hold or keep harvested autograft in place by angling the bone cutting surfaces less than 90 degrees relative to the body or by curving them in ward. Barbs _g_ or surface roughness along the bone cutting surfaces and body may also be used to fix the graft to the stabilizing device.
Dimezzsiozzs azzd Size Razzge In several embodiments, the stabilizing device can be properly sized from precise dimensions of the intervertebral disc geometry of the individual selected for treatment. One skilled in the art will understand that these dimensions can be culled from CAT scan data or similar data from another modality. For example, scans can be used to determine the proper or normal distance between adjacent vertebral bodies and this distance can be used to approximate the height of the stabilizing device. Similarly, data from scans depicting the internal dimensions of the anulus and endplates (in a neutral position) can be used to design the outer shape of the device so that after harvesting bone along the endplates and rotating the stabilizing device, a precise fit is achieved. In one embodiment, the device has a width in the range of about .25 cm to about 7 cm, preferably between about .5 cm to about 6 cm, more preferably between about 1 cm to about 5 cm. In one embodiment, the device has a length in the range of about .25 cm to about 5 cm, preferably between about .5 cm to about 4 cm, more preferably between about 1 cm to about 3 cm. In one embodiment, multiple stabilizing devices are stacked between the same two vertebral bodies. Such stacking, in some embodiments, aid in stability and allow for the use of smaller stabilizing devices.
Delivery Method In one embodiment of the present invention, a method of initiating bony fusion between a first bone and a second bone is provided. In one embodiment, an implant having a body with a longitudinal axis, and at least a first bone cutter and a second bone cutter offset in opposite transverse directions from the longitudinal axis is provided. The implant is introduced between the first and second bones and rotated about its longitudinal axis so that the first and second bone cutters cut fragments from the first and second bones. The implant is left in position between the first and second bones. In some embodiments, a second implant is inserted in between the first and second bones. In one embodiment, bony fusion is initiated between adjacent vertebral bodies. In one embodiment, at least one of the first and second vertebral bodies is in the sacral spine, lumbar spine or cervical spine. In one embodiment, the implant is rotated through no more than one revolution. In another embodiment, the implant is rotated through no more than about 120 degrees. In another embodiment, rotation is stopped at a point where the first bone cutter is in contact with the first bone and the second bone cutter is in contact with the second bone.
In one embodiment, bone growth facilitator is infused through at least a portion of the implant. Bone growth facilitator can be introduced via one or more lumens in the boring instrument or rods, described below, or can be introduced using a separate insertion device. In one embodiment, bone growth facilitator is an integral part of the stabilizing device. In some embodiments, the stabilizing device, or implant, is coupled to a source of bone growth facilitator. W alternative embodiments, the implant is pre-treated with bone growth facilitator.
In several embodiments, more than one stabilizing device is used. In one embodiment, two stabilizing devices are used. In another embodiment, three stabilizing devices are used. In one embodiment, a stabilizing device as described herein is used in connection with one or more structural devices, such as screws, that are used to stabilize the space between two bones by restricting movement.
In one embodiment, insertion of the stabilizing device is performed using an anterior approach, though a lateral approach can also be used. FIG. 10 shows an isometric view of the posterior of a functional spinal unit 100 comprising a superior vertebral body 1, inferior vertebral body 2, an anulus 3, a transverse process 4, and portion of a facet joint 6.
The other posterior elements have been surgically removed. In this embodiment, a posterior approach can be used.
In one embodiment, arthroscopic equipment l~nown in the art may be used to perform a partial or complete discectomy to provide an initial implantation site. A
distraction device can then be used to provide access to the intervertebral space and allow for precise delivery. Alternatively, the stabilizing device itself can be designed with a wedge profile and forcibly inserted across the endplates thereby distracting them. An insertion rod can engage or be placed against the distal or trailing side if the device and used to push the device or as a site to apply the force of a hammer.
In a~i alternative delivery method, the stabilizing device can be used without performing a discectomy or distracting the endplates. In this embodiment, the leading edges of the bone cutting surfaces of the stabilizing device are also sharpened and used to cut straight into the vertebral bodies (across to the endplates) as the stabilizing device is driven between and parallel the adjacent endplates. As the stabilizing device is inserted, a hollow mid-section of the central body can accept the displaced disc material in between.
FIGS. 11A-C show a method of delivery according to one embodiment of the invention. Following the initial implantation between the vertebral bodies 7, 8, one or more drivers 550 or insertion rods are engaged to the device and used to impart axial rotation (driver is not shown) causing the bladed edges of the stabilizing device along its length to gouge and shear off portions of the adjacent endplates 7, 8. These portions are then forced into the adjacent hollow receiving zones of the stabilizing device. Barbs or other means, including, but not limited to spikes, wedges, surface treatments, adhesives (e.g., cyanoacrylate) or some combination thereof, may be used along the stabilizing device surface, or portions of the stabilizing device surface, to retain the harvested bone 600.
After rotation through approximately 90 degrees, the driver 550 or insertion rod is removed. In this orientation, the harvested bone 600 contacts the sidewalls and edges of both vertebrae that now have freshly scraped osteogenic surfaces. The curved and sharpened edges of the stabilizing device lie substantially parallel to the endplates and the harvested bone is flush with or extends beyond their edges to reduce or prevent further cutting or physical trauma. hl one embodiment, a hollow stabilizing device (as shown in FIG. 7) is used to fully shear through the bone in one or more partial or complete revolutions.
FIG. 12A and 12B show an alternative delivery method in which an initial step is added prior to inserting the stabilizing device. Here one or more horizontal holes or slots 905 are punched above each of the endplates as shown. The stabilizing device 500 is hammered into place through the endplates and across the disc space. One advantage of this step is that it facilitates rotation of the stabilizing device 500 (and displacement of the bone grafts).
FIG. 13 shows a cylindrical boring instrument 900 and the cut 910 it makes into the vertebral bodies 1, 2. After the bore 900 has been removed, a device 500 with or without sharpened edges may be inserted and rotated, as described above.
In one or more embodiments discussed herein, initial fixation can be achieved through one or more of vertebral taxis (caused be the tension of the remaining anulus fibers), wedging action and friction. Secondary or permanent fixation via fusion occurs over a period of weeks as the portions of the harvested bone in the stabilizing device fuse to each other and the adjacent vertebrae until eventually the stabilizing device is encapsulated.
W one embodiment of the invention, stabilizing devices of varying sizes and geometries are used to fuse other pathological joints of the body. These joints include, but are not limited to joints of the shoulder, wrist, ankle, knee, hip, and digits. FIG. 14 shows a sagittal view of an anlcle joint, including fibula 980, tibia 986, talus 988 and calcaneus 982.
FIG. 15 shows the ankle bone with an implanted stabilizing device 500. The stabilizing device 500 is used to fuse an ankle joint. In this embodiment, the stabilizing device is inserted along the bones and cartilage between the tibia 986, talus 988, calcaneus 982, an/or fibula 980. In one embodiment, the stabilizing device is implanted between two or more adjacent bones.
