Little Finger

We report a case of closed rupture of the flexor tendons of the little finger caused by calcium pyrophosphate dihydrate crystal deposition disease of the pisotriquetrum joint. The patient could not flex the little finger and did not have wrist pain. Plain radiographs of the affected wrist joint showed severe arthritic changes of the pisotriquetrum joint and calcification around the joint. At operation, the pisotriquetrum joint capsule was ruptured and involved the flexor tendon of the little finger. The distal stump of the flexor tendon was transferred to the flexor tendon of the ring finger, and the pisiform was resected. Histological examination with polarized light microscopy revealed crystals showing weakly positive birefringence in the calcification.
