Abstract: This invention relates to a malleolar implant for partial or total ankle prosthesis, comprising a head, intended to bear against the astragalus or astragalian prosthetic component and a shank provided to be introduced in a bore in the fibula, characterized in that said shank is provided with means for hooking a traction member adapted to be manoeuvred from the outer side of the fibula, in order to position said shank in said bore.

Abstract: A malleolar implant for partial or total ankle prosthesis which includes a head having a surface to bear against an astragalus or astragalian prosthetic component and from which head extends a shank adapted to be inserted through a bore in a fibula wherein the shank is provided with means for hooking a traction member which is adapted to be inserted through the bore in the fibula in order to apply a force to pull the implant into the bore such that the implant is seated within the bore of the fibula.

Abstract: An ankle prosthesis, comprising a tibial element and an talar element (30), each provided with anchoring means on the lower extremity of a tibia and on the astragalus, respectively, and each delimiting an articular surface, both articular surfaces being shaped in order to interact as a whole and to provide a relative movement between the two tibial and talar elements around at last one axis. It is especially characterized by the fact that, taking as reference direction the direction of the axis of the tibia on which it is intended to anchor the tibial element, seen in projection on a plane approximately perpendicular to this reference direction, the articular surfaces are curved with a concavity towards the inside of the foot onto which is to be anchored the talar element.
