Debridement arthroplasty for advanced primary osteoarthritis of the elbow. Results of a new technique used for 29 elbows.

We report the technique and results of a new method of debridement arthroplasty for advanced primary osteoarthritis of the elbow. Triceps and the periosteum of the olecranon are reflected towards the ulnar side and the joint is opened by dividing the radial collateral ligament. Osteophytes are removed, the olecranon and coronoid fossae are deepened and the fibrosed anterior joint capsule is excised. The degenerative changes are always more advanced on the radial side, with erosion of the capitellum, and it is usually necessary to remodel the head of the radius. In 29 elbows reviewed at a mean of 64 months, the average gain of range of motion was 34 degrees, with good pain relief and improved grip in most patients. Two elbows required reoperation but there were no other serious complications.
