Arthroplasty of the proximal interphalangeal joint using the Sutter implant for traumatic joint destruction.

We report the functional results in a series of 21 Sutter arthroplasties for post-traumatic arthritis with an average follow-up of more than 2 years. The dorsal approach was used in every case. Pain was always present preoperatively and mobility was reduced to an average range of motion of 15 degrees. Postoperatively, pain was absent in 18 cases. The average active range of motion was 55 degrees. There were two fractures of implants. Although the follow-up is limited, the Sutter arthroplasty has given results that are similar to, or better than, those reported for other techniques.
