Abstract

A medical foot implant (1) with a fastening section (2) for fixing the foot implant (1) to two adjacent bones or bone segments and with a wedge section (3). The wedge section (3) has an end-side tip (12), in a plan view at least approximately punctiform, for easier introduction of the foot implant (1) into bone or into tarsometatarsal joint.

Claims

1. Medical foot implant comprising a fastening section including a wedge section for fixing a foot implant to two adjacent bones or bone segments, the wedge section has an end-side tip, in the plan view at least approximately punctiform, for introduction of the foot implant into bone or into tarsometatarsal joint.

2. Foot implant according to claim 1, wherein the wedge section comprises four side sections arranged at a right angle to one another, in each case tapering in a direction of their transverse extension viewed from the fastening section in the direction of the end-side tip.

3. Foot implant according to claim 1, wherein at least two opposite side sections of the wedge section are formed concave in the direction of their respective longitudinal extension.

4. Foot implant according to claim 1, wherein an opening extending in a transverse direction is provided in the wedge section.

5. Foot implant according to claim 4, wherein a structured edge delimits the opening.

6. Foot implant according to claim 5, wherein the structural edge of the opening has a serrated structure with teeth arranged adjacent to one another in a peripheral direction, whereby a tooth gap is provided between adjacent teeth.

7. Foot implant according to claim 1, including fixing means for detachably fixing a forcing aid to the wedge section.

8. Foot implant according to claim 1, wherein the fastening section has a first clearance opening for receiving a first bone screw and at least one second clearance opening spaced apart from the first clearance opening for receiving a second bone screw.

9. Foot implant according to claim 8, wherein the first and second clearance openings are made in a plate extending at least approximately perpendicularly to a longitudinal extension of the wedge section for external attachment to two bones or bone segments.

10. Foot implant according to claim 2, wherein two opposite side sections have a width extension of differing size and the same height.

11. Foot implant according to claim 2, wherein two opposite side sections are inclined to one another transversely to their longitudinal extension.

12. Foot implant according to claim 2, wherein at least one blind hole is made in two opposite side sections.

13. Foot implant according to claim 1, wherein the fastening section is one of (a) one piece with the wedge section and (b) detachably fixed to the wedge section.

14. System comprising a foot implant according to claim 1, further including a forcing aid which can be fixed detachably on the foot implant.
