IMPLANTABLE COMPONENT WITH IMPROVED ANCHORING MEDIA FOR ANKLE PROSTHESIS AND ANKLE PROSTHESIS CONSISTING OF SUCH A COMPONENT

摘要

An implantable component with improved anchoring means for ankle prosthesis and ankle prosthesis comprising such a component. The invention relates to an implantable ankle prosthesis component (1), comprising a main body (2) with a bone contact face (3) intended to come into contact with an area of a bony body of an ankle and to contact an area of a bone body of an ankle. extending along a plane (Pc) of median contact, and comprising an anchoring means (4) projecting from the bone contact face (3), the anchoring means (4) comprising two pairs (20A, 20B) d 'anchor wings, each extending respectively in a plane (P1, P2) orthogonal to said plane (Pc) of median contact between a first end (23A, 23B) connected to the face (3) of bone contact and a second opposite end (24A, 24B), the planes (P1, P2) of extension of the pairs (20A, 20B) of anchor wings being intersecting, the second ends (24A, 24B) of the pairs (20A, 20B) d 'anchor wings being inscribed in a plane (Pa) inclined with respect to the plane (Pc) of median contact. Implantable components of ankle prostheses, ankle prostheses. Figure for the abstract: Fig. 1.
