The invention relates to a resorptive intramedullary implant between two bones or two bone fragments. The implant includes a single-piece body () having a generally elongate shape and having, at each end, areas for anchoring to the bone portions in question, characterized in that one of said areas (A) has a cylindrical cross-section while the other area (A) has a flat cross-section.

Resorptive intramedullary implant between two bones or two bone fragments

In one embodiment, the present invention includes an intramedullary osteosynthesis or arthrodesis implant including a central body, a first pair of legs extending from the central body to a pair of leg tips, and a second pair of legs extending from the central body, in a direction opposite the first pair of legs, to a pair of leg tips such that the central body, first pair of legs and second pair of legs are positioned alongside a longitudinal axis.

Osteosynthesis device

The invention relates to a plate fixed between two bone parts by way of screws engaged in holes formed in the thickness of said plate. The plate comprises an angled member or rib which is inclined according to an angle of between about 30&#xb0; and 60&#xb0; in relation to the plane defined by the plate. The angled member or rib has a hole for engaging a screw and is located in the central part of the width, over a determined part of the length of the plate, so that the screw brings the two bone parts into a compressive position.

Orthopedic implant in the form of a plate to be fixed between two bone parts

In one embodiment, the present invention is a method of arthrodesis or osteosyntheses of a first bone part and a second bone part, including the steps of positioning a first fixation zone of an implant in the first bone part and a second fixation zone of the implant in the second bone part, both the first and second zones made of shape-memory material and, prior to positioning the bone parts, are in an inner position; and while the first fixation zone is within the first bone part and the second fixation zone is within the second bone part, fixating the respective first and second fixation zones within the respective bone parts through shape-memory action at body temperature.

Device for osteosyntheses or arthrodesis of two-bone parts, in particular of the hand and/or foot

In one embodiment, the present disclosure is a fixation device including a median zone, a first fixation zone including a base region extending from the median zone and an end region distant from the median zone, and including an expandable region in between the base region and the end region, the expandable region adapted to move between a closed position and an expanded position, wherein the first fixation zone is adapted to be positioned within a bone hole and, with the expandable region in the expanded position, the expandable region is positioned against bone surrounding the bone hole, and a second fixation zone including a base region extending from the median zone at a position different from the base region of the first fixation zone and an end region distant from the median zone.

Device for osteosyntheses or arthrodesis of two-bone parts, in particular of the hand and / or foot

In one embodiment, the present invention is a fixation device including a median zone having a substantially triangular shape; a first fixation zone including first and second tabs that, in a separated configuration, extend away from each other from an end of the median zone, the first fixation zone having a first region adjacent the median zone and a second region adjacent the first region. Also, within the first region of the first fixation zone, an inner surface of each of the first and second tabs of the first fixation zone extends outwardly and proximally from the median zone to a first point to form an arch, and from the first point, the inner surface of each of the first and second tabs extends toward a second point. Further, within the second region of the first fixation zone, the inner surface of each of the first and second tabs of the first fixation zone extends outwardly from each second point to a respective third point so that the inner surface of each of the first and second tabs from the second point to the third point is arcuate and convex.

Method of osteosyntheses or arthrodesis of two-bone parts, in particular of the hand and / or foot

The invention relates to a self-tapping and self-boring osteosynthesis screw for compressive orthopaedic surgery, characterised in that, in the bone engagement regions, at both the distal portion (A) and at the proximal portion (A), the sum of the angles defining the outer taper of the shank (f) and the taper of the crest line of the screw thread pitch (P) is higher than 45&#xb0;, and in that the leading portion (i.e. the most distal one) of each thread includes a plurality of cutting edges (AR) obtained by stock removal.
