Linburg-Comstock syndrome: a case report.

We report a case of Linburg-Comstock syndrome, which is characterized with anomalous tendon slips connecting flexor pollicis longus (FPL) to the flexor digitorum profundus (FDP), usually at the index finger. The present patient started to be a carpenter and was suffering from his disability of flexing the thumb and the index finger independently when he handled the screws in his work. We surgically removed the tendinous connection of the FPL tendon and the index FDP tendon. After surgery, he could work as a carpenter without any difficulty. Surgical disconnection was effective treatment. Dynamic high-resolution ultrasound and three dimensions of computed tomography of the left distal forearm were helpful to confirm the diagnosis.
