Abstract:
A multi-configurable wrist joint prosthesis comprising: a carpus element to be implanted in the metacarpal bones, a radial element including a stem having a first axis, said stem to be implanted in the ulna bone, and a transverse axis articulator including a distal part having a second axis, said distal part rigidly connected to said carpus element, said transverse axis articulator further comprising first and second alternatively installable proximal parts which are alternatively releasably installable between said radial element and said distal part when said carpus element is implanted in the metacarpal bones and the stem of said radial element is implanted in the ulna bone, each of said first and second proximal parts including a releasable articulation receptacle for receiving said distal part and a releasable connecting arrangement configured to rigidly attach to the stem of said radial element; wherein installation of said first proximal part limits articulation of said carpus element to a range of rotation about said second axis and alternate installation of said second proximal part permits articulation of said carpus element in a range of motion about said second axis and a range of pivot relative to said first axis.
