An orthopaedic implant used in arthroplasty of the fingers comprises a first element for a proximal phalanx and a second element for an adjacent distal phalanx, each element having a respective stem for implantation in the bone and an interphalangeal articulation head, the head of the first element having a biconvex surface of articulation, with a central valley, and the head of the second element having a biconcave surface of articulation designed to cooperate with said convex surface and comprising a central crest. At rest, the surfaces are congruent in the frontal plane of the articulation in the area of the condyles and non-congruent in the sagittal plane.
