Definitions
- the invention relates to a reduction and fixation system, with which bone fragments can be repositioned and subsequently fixed.
- Bone fragments have been fixed relative to each other for over 100 years with the help of bone plates, screws and nails.
- the fixation of bone fragments by means of classical bone plates presupposes that the bone fragments have already been repositioned, ie they are in the correct position with respect to each other.
- the classic bone plate is placed on the reduced bone fragments and attached to the bone fragments with screws or nails.
- a Repositions- and fixation system of two hingedly interconnected bone plates is also known.
- the two bone plates are connected to different bone fragments. It is not necessary that the bone fragments are already reduced to their final position when attaching the bone plates. Rather, the bone plates with the attached bone fragments can be pivoted about the hinge axis against each other to reposition the bone fragments.
- Such a reduction and fixation system is offered for the distal radius of the radius of the wrist.
- a disadvantage of the known reduction and fixation system is that in many cases it is difficult to fix the bone fragments repositioned by pivoting the bone plates in the final position.
- the invention has for its object to present a reduction and fixation system that facilitates the fixation of the bone fragments after repositioning. The object is solved by the features of claim 1. Advantageous embodiments can be found in the subclaims.
- the reduction and fixation system comprises at least two bone plates which are designed to be connected to one another. Depending on requirements, any number of bone plates can be connected to one another. Each bone plate is equipped with a lug for connection to another bone plate.
- the neck element of a first bone plate comprises a plurality of projections.
- the neck element of a second bone plate comprises an opening. In a first connection state, the projections engage the opening and establish a hinge-like connection between the first bone plate and the second bone plate. In a second connection state, the projections are under tension and provide a rigid connection between the first bone plate and the second bone plate.
- a hinge-like connection of two bone plates in the context of the invention means a connection which, as the only movement, permits a pivoting of the bone plates about the hinge axis. In a rigid connection, no movement of the bone plates relative to each other longer possible.
- bone fragments attached to the bone plates can be reduced by pivoting the bone plates. Once the bone fragments have been brought into their final position, the projections can be tensioned so that the bone plates are rigidly connected. The bone fragments associated with the bone plates are thus fixed in their final position.
- the first bone plate has a bore and the projections are arranged on the circumference of the bore.
- a bore opens up the possibility of passing a screw through the opening in the second bone plate and the bore in the first bone plate and screwing it to an adjacent bone fragment.
- the tensile force generated by screwing in the screw can also be used to put the projections under tension in the second connection state.
- the head of the screw engages the projections and puts them under tension.
- the head of the screw may have a conical outer shape for this purpose.
- the screw is also in a rigid connection with the first and second bone plate without stopping in a bone fragment. It is possible that the opening tion in the second bone plate or the bore in the first bone plate has a thread which cooperates with the thread of the screw. By means of this thread, the projections can be put under tension independently of the holding force of the adjoining bone fragment and in this way a rigid connection between the first bone plate, the second bone plate and the screw can be made.
- the opening or the bore is not initially provided with a thread, but if the thread is generated only when screwing the screw.
- the thread of the screw and the wall of the opening or the bore cooperate when screwing in the screw in such a way that the wall of the opening or the bore is subjected to a cold forming.
- the bone plate may have a region of reduced hardness in the area around the opening or bore, cf. DE 196 29 011 A1.
- a screw head on harder titanium material can be molded into a region of the bone plate made of softer titanium.
- the screwing in of the screw and the associated cold forming can be further facilitated if the material thickness in this area is reduced.
- the wall of the opening or bore may have a narrowing with a smaller material thickness in the form of a ridge, a lip or an edge, cf. EP 1 211 993 Bl.
- the first bone plate and the second bone plate are present as separate parts.
- the projections of the first bone plate are brought into engagement with the opening of the second bone plate.
- two portions of the projections are distinguished.
- the projections protrude out of the plane spanned by the first bone plate.
- a bone plate near portion of a projection adjacent to the first bone plate, on the bone plate near portion of the projection is connected to the first bone plate.
- the bone plate distal portion of a projection is remote from the first bone plate, it forms the free end of a projection.
- the projections may be formed in such a way that their bone-plate distant portions can be connected in a relaxed state with an imaginary circular line and that the diameter of the circular line is greater than the diameter opening in the second bone plate.
- the projections When the opening is pushed onto the projections, the projections are stretched inwards, so that the diameter of the imaginary circular line can be reduced and the opening can be pushed over the bone-distant ends of the projections.
- the bone plate near portions of the projections are preferably designed such that they are relaxed in relaxed was connected to an imaginary circular line whose diameter corresponds to the diameter of the opening of the second bone plate.
- the projections snap back from their inwardly tensioned position to the relaxed position.
- the bone plate near portions of the projections abut the inner periphery of the opening.
- the inner wall of the opening rotates with respect to the projections.
- the bone plate near portions of the projections together with the inner wall of the opening form the bearing of the hinge-like connection between the first and the second bone plate.
- the opening in the second bone plate, in which engage the projections may be formed so that it surrounds the projections in the first VietnamesegsSullivan all around.
- a bead may be formed on the inner wall of the opening, which is engaged behind by the projections.
- the rigid connection, which in the second connection state between the first bone plate and the second bone plate, is created by the projections are put under tension.
- the tension may be that the projections are spread.
- the friction between the projections and the inner wall of the opening increases, so that the bearing of the hinge-like connection has a considerably increased resistance.
- the tension of the projections not only causes an outward spreading force, but at the same time a force through the second bone plate is pressed against the first bone plate.
- Such a combined force effect can be achieved, for example, by tilting the projections.
- the combined force also causes friction to increase in the bearing area in which the first bone plate and the second bone plate lie flat on one another.
- the resistance-increasing effect of the friction in the support area can be further enhanced if at least one of the bone plates in the support area increases.
- the friction is to make it difficult to pivot between the first bone plate and the second bone plate.
- the ridges and depressions then provide the greatest resistance to a pivoting movement when they are radial to the bore in the
- one or more bone plates have more than one
- Bone plates which have an elongated shape have proven suitable for use in the reduction and fixation system according to the invention. Except for the approach
- the bone plates may have further holes through which bone plate can be connected to bone fragments. Normal screws can be used in these holes. But it is also possible to use screws, which are in the way of cold forming with
- Bone fragments may be displaced by adherent muscles. Soft tissues may be trapped between the bone fragments. Access to the fracture area may be hampered by overlying soft tissues. In these cases it may be difficult to find suitable starting points for reduction forceps. Sometimes it is necessary to screw a bone plate to a bone fragment to create a point of attachment for a reduction tool.
- the reduction and fixation system comprises two elongated bone plates, each having a arranged in the center of the bone plate neck element. From an arranged in the center lug element is when the lug element is spaced from both ends of the bone plate. The counterpart is the attachment elements arranged on the periphery. If the two bone plates are connected together in their center, they represent a scissors-like structure. The hinge of the scissors-like structure can be used as a fulcrum. Two ends of the scissors-like structure are attached to two bone fragments.
- the scissors-like structure can be attacked with a pair of pliers to move the bone fragments relative to each other. Will the scissors with the help of Pliers spread, so the bone fragments are spread apart. Trapped soft tissues can be solved. By closing the scissors, the bone fragments can then be brought together so that they come to rest next to each other. In particular, the bone plates can be used in this way, even if the access to the fracture area with large Repositionszan- gene is not possible.
- the reduction and fixation system may also include four bone plates, each having two lobes located at the periphery. These bone plates can be connected together in such a way that they form a rectangle as a whole, whose legs can be pivoted against each other in a hinge-like manner. Now, if two legs of the quadrilateral are connected with bone fragments, it can be attacked with a pair of pliers on the other two bone fragments to move the bone fragments relative to each other.
- This embodiment of the reposition and fixation system can also be advantageously used if the fracture area is not directly accessible for reduction forceps. Furthermore, this embodiment is suitable when a large number of bone fragments has to be reduced. This is often the case with fractures of the pelvic bone or the scapula, for example.
- the reduction and fixation system again comprises four bone plates, each of which has an attachment element arranged in the center and at the periphery of the bone plate. Two bone plates in the center are connected to each other, so that a scissors-like structure is formed. The two scissors are closed by the peripheral attachment elements a scissors-like structure interconnected. If necessary, a plurality of scissor-like structures can be linked to form a longer scissors grid. With a collet reduction and fixation system, a larger distance between the fracture area and the fracture area can be achieved
- a flat scissor lattice can be used in particular when bone fragments of a flat bone such as the pelvic bone or the scapula have to be repositioned.
- the scissor-type structure also has the advantage of providing a gear ratio in which the forceps travel a great distance, while the bone fragments connected to the opposite end move only a short distance.
- This embodiment is therefore particularly suitable when a considerable force is required to reposition the bone fragments.
- the embodiments in which the reduction and fixation system is used as a lever or provides a starting point for a pair of pliers, deserve protection independently of the
- the scissors and lattice-like structures can be combined in a suitable manner with other bone plates.

- Fig. 13 a reduction and fixation system of six
- FIG. 14 shows the reduction and fixation system from FIG. 13 with two further bone plates.
- the reduction and fixation system comprises a first bone plate 1 (Fig. 1) and a second bone plate 2 (Fig. 2).
- the first bone plate 1 has a bore 3 and four projections 4 arranged on the circumference of the bore 3.
- the projections 4 form a lug for connection to another bone plate.
- the bone plate 1 has further holes 5.
- the second bone plate 2 is equipped with an opening 6.
- the opening 6 forms a lug element for connection to a further bone plate.
- the projections 4 comprise a bone plate near section 41 and a bone plate distal section 42.
- the bone plate distal sections 42 of the projections 4 can be surrounded by an imaginary circle whose diameter is greater than the smallest diameter of the opening 6.
- the smallest diameter of the opening 6 becomes formed by a bead 61 in the wall of the opening.
- the bone plate near portions 41 of the projections 4 can be surrounded with an imaginary circular line whose diameter corresponds to the smallest diameter of the opening 6.
- the projections 4 of the first bone plate 1 are inserted into the opening 6 of the bone plate 2.
- the projections 4 In order to introduce the bone plate distal portions 42 in the opening 6, the projections 4 must be stretched inwards so that they can be surrounded by an imaginary circular line whose diameter is not greater than the diameter of the bead 61. Tensioned inward are the Projections 4 by the opening 6 is placed on the projections 4 and the first bone plate 1 and the second bone plate 2 are compressed. The bead 61 biases the projections 4 inward, slides past the bone plate distal portions 42 of the projections 4 and comes to lie next to the bone plate near portions 41 of the projections 4. The projections 4 return to the relaxed starting position.
- the bone plate remote portions 42 of the projections 4 engage behind the bead 61 in the opening 6, so that the second bone plate 2 can not be readily withdrawn from the first bone plate 1 again.
- the only movement which the second bone plate 2 can still make relative to the first bone plate 1 is a pivoting movement about the axis of the opening 6.
- the bearing for this pivoting movement is formed by the bead 61 and the bone plate near portions 41 of the projections 4.
- a screw 7 through the opening 6 in the first bone plate 1 and the Drilled hole 3 in the second bone plate 2 and screwed into a fitting on the first bone plate 1 bone fragment 8. Due to the tensile force of the screw 7, the head 71 of the screw 7 is pressed against the projections 4. The projections 4 are spread, so that the bone plate near portions 41 of the projections 4 are pressed against the bead 61. The bearing formed by the bead 61 and the projections 4 is locked. A pivoting of the first bone plate 1 relative to the second bone plate 2 is no longer possible.
- the bore 3 has a lip-shaped constriction 31.
- the diameter of the opening 31 enclosed by the constriction 31 is smaller than the outer diameter of the screw 7.
- Screw 7 cuts a thread in the constriction 31, wherein at the same time the material of the screw 7 firmly connects with the material of the lip-shaped constriction 31. The result is a rigid connection between the screw 7 and the first bone plate 1, through which the second bone plate 2 is brought into a rigid connection with the first bone plate 1.
- the described reduction and fixation system is first brought into the first connection state, Fig. 3.
- the first bone plate 1 is fastened with screws to a bone fragment.
- Normal screws can be used, which are passed through the bore 5.

- the opening 63 is arranged in the center of the bone plate 21, the openings 62 are arranged on the periphery of the bone plate 21. With each of the openings 62, 63, another bone plate can be connected. Through the holes 5 screws can be passed, which are screwed into bone fragments.
- the Bone plate 22 of FIG. 9 has two openings 62 formed as attachment elements as well as two holes 5 located therebetween. To the bone plates 21, 22 analogous bone plates, which instead of the openings 62, 63 have projections 4 are not shown.
- the bone plates 21, 22 can be combined with each other in various ways. Some combinations are shown in FIGS. 10 to 14. In FIG. 10, two bone plates 21 are connected to each other in a scissor-like manner via the central opening 63. If the bone plates 21 are connected via the bores 81 with bone fragments, it can be attacked at the opposite ends of the scissors-like structure with a pair of pliers to reposition the bone fragments.
- Fig. 11 eight bone plates 22 are connected to each other via the peripheral openings 62. All bone plates 22 can be pivoted relative to each other. For example, it is possible to screw three bone fragments over the holes 82 and to reduce this by suitable pivoting of the bone plates 22.
- This embodiment is particularly suitable for flat bones such as the pelvic bone and the shoulder terblatt, where a plurality of bone fragments can be reduced.
- FIG. 12 is based on the scissors-type structure shown in FIG.
