A chrome-cobalt hinged prosthesis has been specially designed for total replacement of elbow joints disorganised by rheumatoid arthritis, and has been used in twelve patients over the last two years. 2. The technique of insertion includes fixation of the two main portions in the humerus and in the ulna by acrylic cement before they are joined by an axis pin. 3. Ten of the twelve patients obtained 90 degrees or more of painless movement and good muscle control of the artificial joint. 4. The results to date suggest that the prosthesis and surgical technique have a wider application than for rheumatoid arthritis.
