PROSTHESIS FOR TOTAL ARTHROPLASTY OF THE ELBOW JOINT

摘要

A prosthesis for total replacement arthroplasty of the elbow joint consists of a hinge joint having two intramedullary stems adapted for insertion into the medullary canals of the humerus and the ulna respectively, and which is articulated at the time of operation. The free end of one of the stems is formed with an integral partial cylinder within which is secured a cylindrical bearing member formed of ultra high density polyethylene having an axial bore for receiving a pivot pin carried on the free end of the other stem. A radial slot in the bearing member, of a width slightly less than the diameter of the pivot pin, allows the pin to be snapped into the bore of the bearing member to form the hinge joint.
