The application relates to a prosthetic canine elbow joint (1) comprising a radioulnarcomponent (12) mountable in a trochlear notch of the ulna (2) and an articularfovea of a radius which is engagable with a humeral component (10) mountable ona trochlear bone portion of a humerus (4) to permit relative movement betweenthe humerus (4) and ulna (2). The humeral component (10) is thus mounted e.g. hookedstably on a piece of bone extending between the medial and lateral condyles therebymaking use of the intrinsic strength of bone. The humeral component (10) may includean opening (26) alignable with the supratrochlear foramen to receive the anconealprocess (6) of the ulna (2) during articulation of the joint, thereby promotingfreedom of movement.
