Treatment of Distal Radioulnar Joint in Rheumatoid Arthritis.

Arthritis of the distal radioulnar joint is a frequent source of pain and disability for patients with rheumatoid arthritis despite advances in medical treatment. Treatment options include distal ulna resection, distal radioulnar joint fusion, and distal radioulnar joint arthroplasty. Before surgery, careful evaluation should be performed for concurrent pathology, including extensor tendon rupture and involvement of the cervical spine. Patients' age and activity level must be considered when determining the ideal treatment.
