Abstract: The invention relates to a shoulder prosthesis comprising a diaphyseal part extending along a diaphyseal axis and on which an epiphyseal part is mounted, the epiphyseal part having an upper face which is inclined along a front plane with respect to the diaphyseal axis, and a lower central face bearing against a complementary upper face of the diaphyseal part. According to the invention, the epiphyseal part is reversible by rotation through 180° about an axis normal to the lower central face bearing against the epiphyseal part to modify the inclination of the upper face of the epiphyseal part.

Abstract: The invention relates to a fixation system between a medical device and at least one portion of a bone, characterised in that it comprises an elongate portion intended to be inserted into the bone, in particular into the medullary cavity and/or into the proximal or distal ends, the elongate portion having a wall consisting of meshes through which at least one fixing member can pass, according to a position and orientation that are not predefined, and which apply, by elastic, plastic or elastic-plastic deformation, a transverse and/or axial pressure force onto the fixing member, the fixing member being intended to also pass through the portion of the bone in order to ensure rigid fixation between the bone and the medical device.

Abstract: Surgical implant for treating fractures of long bones, notably of the femur, having an intramedullary section (52) of elongated shape, adapted for being inserted into the medullary cavity (37), an extramedullary section (56) substantially parallel to the intramedullary section (52), a deformable curved loop (57) connecting the intramedullary section (52) to the extramedullary section (56), an inclined screw (61) traversing said intramedullary section (52) and said extramedullary section (56). By deforming the loop (57), a continuous adjustment of the angle (?) of the cephalic screw (61) and thus an optimal adaptation of the implant to the individual anatomy can be achieved. Thanks to its geometry, this implant induces a protection of the greater trochanter and limits the mechanical loads between the cephalic screw (61) and the rest of the implant.
