Tendon interposition arthroplasty after resection of necrotic carpal bone

Thirty seven patients with a necrotic lunate or a partially necrotic scaphoid bone underwent surgery. The necrotic bone was replaced with autologous tendons. The late follow-up examination showed good stability within the carpal skeleton and no progression of the osteoarthritis. The patients reported marked relief of symptoms and improved function of the wrist. Postoperative active motion and strength were only slightly impaired. Very few complications and a smooth professional rehabilitation characterize this surgical procedure.
