Claim:
1. An arthrodesis prosthesis for implantation in an animal or human subject for preventing pronation or supination at the wrist joint, said prosthesis comprising a first component for attaching to a radius bone in use and a second component for attaching to an ulna bone in use, the prosthesis further comprising a linkage for linking the first and second components with respect to one another in use, wherein the prosthesis is configurable to allow the linkage to move relative to at least one of the first and second components to allow for adjustment of the linkage relative to said at least one of the first and second components to a selected position and is configurable to be retained substantially rigidly at said select position, such that the first and second components can be retained substantially rigidly relative to one another in normal use in a fixed configuration relative to one another, and wherein the linkage includes a locking mechanism capable of rigidly locking the first and second components at a selectable position and the linkage is configurable to allow the linkage to move relative to the at least one of the first and second components to provide at least two degrees of freedom of movement of the first component relative to the second component when adjusting the linkage to said selected position.
