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

ABSTRACT

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
