Abstract: An implant, of intramedullary implant type, suited for securing a first bone fragment to a second bone fragment following transverse osteotomy, includes: a plate having a planar lateral face shaped to be secured to the second bone fragment, a shank shaped to be inserted into a medullary canal of the first bone fragment, and an intermediate portion, connecting the plate to the shank, the implant being characterized in that the shank is a solid of revolution centred on a longitudinal axis, the longitudinal axis being parallel to the lateral face of the plate.

Abstract: 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.

Abstract: 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.
