PROSTHETIC DEVICE FOR TOTAL JOINT REPLACEMENT IN SMALL JOINT ARTHROPLASTY
The prosthesis device can have a pair of articular members adapted to be mounted onto adjoining bones, respectively, to replace a joint. The first and second articular members can have first and second bearing elements, respectively. The bearing elements can be formed to be capable of replacing at least a portion of the bone ends of the adjoining bones, respectively, and providing an articulation close to that of a natural joint. The bearing elements can be fixed to the respective bones through an initial implant fixation achieved by press-fit anchoring immediately after surgery and/or a secondary implant fixation established from bone-ingrowth.
