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 present invention concerns a reusable surgical guide for osteosynthesis surgery, forming an aimer for guiding and inserting axial wires into bone portions; said guide comprises a grip constituted by a head extending at the upper end of a base, a trigger adapted to be displaced in a first slide formed in the head of the grip and whose distal end is provided with a through hole for the insertion of a wire, a blade secured to the distal end of the head of the grip, under the trigger, and a so-called aiming piece adapted to be displaced in a second slide formed in the base of the grip, said aiming piece comprising at the distal end thereof means for supporting at least one wire.

Reusable surgical guide for osteosynthesis surgery in particular of the hallux valgus

An osteosynthesis plate includes a plate body in which there is formed an anchor through-orifice having a first orifice region and the second orifice region which are secant and joined by an intermediate region, the first orifice region being of plain cylindrical overall form and coinciding with a first virtual cylinder, the second orifice region having a second upper segment of plain spherical or frustoconical overall shape centred on a second axis and a second lower segment of threaded cylindrical overall shape and coinciding with a second virtual cylinder intersecting the first virtual cylinder, a helical rib being formed in the second orifice region to define a screw thread having a screw thread external radius smaller than the major radius of the second upper segment, and the intermediate region being formed of two planar intermediate faces facing one another.

Osteosynthesis plate with an anchoring orifice intended to cooperate with an osteosynthesis screw for compression of two bone fragments

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

A surgical implant which includes: a first anchoring portion comprising two first arms movable between an inserting position and an anchoring position, in which the first arms are spread apart so as to be anchored in a first bone; a second anchoring portion to be anchored in the second bone; and an intermediate portion connecting the first anchoring portion to the second anchoring portion. The intermediate portion comprises: a recess; and a first connecting portion and a second connecting portion that are remote from one another. Bringing the first connecting portion and second connecting portion closer together moves the first arms from the inserting position thereof to the anchoring position thereof.

Surgical implant for fusion between two bone portions and a clamping ancillary for clamping such a surgical implant

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.
