Rheumatoid flexor tenosynovitis and rupture

Rheumatoid flexor tenosynovitis at the wrist can cause locking, limitation of motion, nerve compression, and rupture of tendons. To prevent and treat these conditions, a flexor tenosynovectomy, combined with nerve decompression and tendon reconstruction as indicated, is necessary. If tendons are ruptured, the flexor pollicis longus and profundus to the index finger are most commonly affected. On the fingers flexor tenosynovitis can also cause locking, decrease in range of motion and rupture tendons. Flexor tenosynovitis of the fingers should be treated with decompression of the tendons health with preservation of the pulley system.
