Symptomatic tendon subluxation after surgical release for deQuervain's disease treated by Brachioradialis tendon flap

Symptomatic palmar subluxation of the abductor pollicis longus and the extensor pollicis brevis tendons developed in a 23 years old man after surgical release for deQuervain's disease. The sub- luxation occurred with the wrist in flexion and the thumb in pal- mar abduction. Nonoperative treatment was ineffective. Surgery was performed to reconstruct a new tendon restraint using a distally based flap from the brachioradialis tendon. Twenty months postoperatively the patient was free of tendon subluxation or pain and had full motion and power of his wrist
