LINBURG-COMSTOCK PHENOMENON FOLLOWING FOREARM LACERATION

A 20-year-old man presented with an inability to flex the interphalangeal joint of the right thumb without simultaneous flexion of the distal interphalangeal joint of the index finger following a penetrating injury to the right forearm. With a clinical suspicion of intertendinous adhesions between the flexor pollicis longus and the flexor digitorum profundus to the index finger, surgical exploration under wide-awake anesthesia was performed. Intraoperatively, the intertendinous adhesions were identified and divided completely. Postoperatively, the patient achieved good, independent flexion of the interphalangeal joint of the thumb. This case demonstrates a clinical picture similar to that of Linburg-Comstock syndrome, which occurred following a forearm penetrating injury. We call this the Linburg-Comstock (LC) phenomenon.
