Abstract

Linburg-Comstock phenomenon is defined simultaneous flexion of thumb and other fingers. The coupling of the flexor pollicis longus and flexor digitorum profundus tendons is the main pathognomonic feature of this lesion. Typically, pain is noted at the distal level of the forearm at the site of the abnormal connection. We describe a case of flexor pollicis longus tendon rupture who undergoes a carpal tunnel release, and report the Linburg-Comstock syndrome after the flexor tendon reconstruction.
