Canine prosthetic elbow joint

摘要

The application relates to a prosthetic canine elbow joint (1) comprising a radioulnar component (12) mountable in a trochlear notch of the ulna (2) and an articular fovea of a radius which is engagable with a humeral component (10) mountable on a trochlear bone portion of a humerus (4) to permit relative movement between the humerus (4) and ulna (2). The humeral component (10) is thus mounted e.g. hooked stably on a piece of bone extending between the medial and lateral condyles thereby making use of the intrinsic strength of bone. The humeral component (10) may include an opening (26) alignable with the supratrochlear foramen to receive the anconeal process (6) of the ulna (2) during articulation of the joint, thereby promoting freedom of movement.
