The invention concerns a prosthesis, in particular for the ankle, comprising two nesting elements (2, 4) assigned to a respective bone (12, 22) and an intermediate element (6) interposed between them for relative articulation. The invention also concerns instruments for implanting said prosthesis. The tibial element (2) comprises a centring brace (10) provided with means to be gripped by the practitioner for extraction, consisting of a bend (24) in the brace (10) and by facets (26, 28) provided at its distal end. The ankle bone element (4) comprises a plane (44) for longitudinal support against the ankle bone (22). A specific instrument enables to centre the ankle bone element (4) relative to the tibial element (2). |
