Distal Radioulnar Joint Implant Arthroplasty

Abstract

Resection of the distal ulna for posttraumatic arthritis and treatment of arthritis and instability of the distal radioulnar joint can be improved with distal ulna prosthetic replacement. In this review, the anatomy, mechanics (kinematics and kinetics), rationale, and indications for surgical replacement of the distal ulna are presented. The surgical technique is precise and the important tenets of proper ulnar head implant insertion provides a guide for use of the implant. Preliminary results after 2 years of clinical experience are most encouraging.
