An anatomical prosthesis for implantation after a resection of the distal ulna includes a head and a stem. The head is formed with a curved surface for articulation with the sigmoid notch of the distal radius. A bore is provided in the head to allow for attachment of the head to the stem. The head is further formed with suture holes for anchoring the head to the soft tissues such as the ulnar collateral capsule, the triangular fibrocartilage and the extensor carpi ulnaris subsheath that are exposed after resection of the distal ulna. The stem is elongated, having a proximal end for engagement with the intramedullary canal of the ulna, and a distal end for engagement with the bore formed in the head.
A prosthesis for implantation to replace the distal ulna in the forearm of a patient, after the resection of the distal ulna, wherein the resection exposes soft tissue that was formerly in contact with the distal ulna, said prosthesis comprising:
