Definitions
- the invention relates to an implant for mutually fixing two bone fragments, in particular for fixing an axially corrected head of a metatarsal bone, e.g. Hallux valgus.
- Osteotomies for the treatment of hallux valgus have been known for decades and aim to functionally reconstruct the axis of the metatarsal I. It is necessary to fix the two bone fragments in their corrected position after the osteotomy in order to prevent interfragmentary mobility and to enable safe bony healing without dislocation.
- Bone clips are also known for fixing the osteotomy, but their use entails the risk of bone splintering.
- an implant for the mutual fixation of two bone fragments in particular for the treatment of an axial deformity of a metatarsal bone, for example hallux valgus, has become known, which has a brace with two legs which are connected to one another at one end and in the other Limit an area through which a screw that can be screwed into one of the two bone fragments is passed, and which can be inserted and expanded with its other, free ends into the medullary cavity of the other bone fragment are.
- the free ends of the two legs are inserted proximally into the medullary canal of one bone fragment and spread out in this medullary canal, whereupon the brace is anchored to the other bone fragment by the screw passed through the opening.
- the intramedullary part of this known implant has a high stability due to the spreading force and the frictional engagement of the brace legs as well as due to the intermittent compression that occurs under functional load.
- the extramedullary part is only anchored in the bone with a screw, but requires a two-point support because of the torque that increases as the compression of the lag screw anchor between the implant and the metatarsal head decreases.
- the present invention has set itself the task of improving the fixation of this known implant with one of the two bone fragments, which is connected to the implant via the screw, and to make it stable without the need to change the surgical technique.
- the invention proposes that between the clasp opening and the
- Screw head is provided with an insert part penetrated by the screw with attachments that can be anchored in the bone fragment.
- the insert part is preferably designed in the form of a ring and has serrations projecting essentially vertically from the ring plane, which are hammered or pressed into the bone fragment and thus anchor themselves securely in the bone fragment.
- a preferred embodiment of the implant according to the invention is characterized in that the insert part has a recess which positively accommodates the clasp in the region of the opening and a lateral slot for the legs of the clasp to pass through. This embodiment results in a positive connection between the insert part and the clasp and thereby reliably prevents the clasp from rotating about the screw axis.
- the insert part is pressed onto the bone fragment (or vice versa) and a change in the position of the tines hammered into the bone fragment is prevented.
- the invention enables the two bone fragments to be directly and stably connected to one another even without special bone incision guidance.
- the insert part has at least three protruding lugs.
- This insert part preferably consists of a material compatible with tissue, for example of stainless steel according to ISO 5832/1.
- FIG. 1 shows the use of the implant according to the invention in the reconstruction of a hallux valgus.
- FIG. 2 shows the clip forming part of the implant according to the invention in plan view and
- FIG. 3 shows the individual parts of the implant according to the invention in side view, in an exploded view.
- 4 shows a bottom view of the insert part of the implant according to the invention and
- FIG. 5 shows a section along the line V-V in FIG. 4.
- Fig. 1 is a metatarsal 1 after
- This implant according to the invention consists of a clasp 4, an insert part 5 and a bone screw 6.
- the clasp 4 has two legs 7 which are connected to one another at one end and there delimit an eyelet-shaped opening 8.
- the free ends of the two legs 7 are inserted into the medullary cavity of the bone fragment 2 and assume their spread position shown in FIG. 2, as a result of which the brace 4 is anchored in this medullary cavity.
- This anchoring is supported by a corrugation, preferably running in the leg plane.
- the clip 4 is then anchored in the bone fragment 3 by the bone screw 6, which is passed through the opening 8.
- the insert part 5 is now provided between the head 9 of the screw 6 and the clasp 4 in the region of the opening 8, which is ring-shaped and has an opening 10 whose diameter corresponds approximately to that of the opening 8. This diameter is smaller than the diameter of the head 9 of the screw 6, so that this head 9 rests on the insert part 5.
- the insert part 5 has serrations 11 which are hammered into this bone fragment before the bone screw 6 is screwed into the bone fragment 3.
- the insert part 5 is provided with a recess 12 in the form of an annular groove, which is adapted to the dimensions of the eyelet part of the clip 4 and receives this area of the opening 8, and has a lateral slot 13 through which the legs 7 of the clip 4 emerge can.
- the insert part 5 is positively connected to the clasp 4, and there is a relative movement between the insert 5 and the clasp 4 prevented.
- the insert part 5 is firmly and non-rotatably anchored to the bone fragment 2 by the bone screw 6 and the lugs 11.
- the clip 4 is thus also prevented from moving relative to the bone fragment.
