'Intersection syndrome' of the foot: treated by endoscopic release of master knot of Henry.

摘要

Intersection syndrome of the forearm is a painful condition in the area where the muscle bellies of the abductor pollicis longus and extensor pollicis brevis cross the common wrist extensors. A similar case of the foot with marked fibrosis at the interconnection of flexor hallucis longus and flexor digitorum tendons is reported and the fibrous interconnection was extended proximally. This was successfully treated with endoscopic release of the master knot of Henry.
