Abstract

The authors report the case of a 39-year-old woman with pain in the right dominant hand after initiating a crafts course. Clinical examination revealed tenderness on the volar side of the thumb and wrist. Simultaneous flexion of the distal interphalangeal joint of the index finger with flexion of the interphalangeal joint of the thumb was observed. Operative procedure confirmed the presumed diagnosis of an anomalous connection between the flexor pollicis longus and the flexor digitorum profundus tendon to the index finger, first described in 1979 by Linburg and Comstock.
