title: Rupture of flexor tendons due to pisotriquetral osteoarthritis.
abstract: We are reporting a case of a flexor profundus tendon rupture of the little finger due to pisotriquetral osteoarthrosis. Resection of the pisiform bone and resurfacing of the carpal tunnel with the joint capsule was performed for the osteoarthrosis and free tendon grafting for the tendon rupture. The tendon grafting and a subsequent tenolysis restored the function of the little finger. Other than radiological changes in the pisotriquetral joint, the diagnostic value of preoperative radiocarpal arthrography was emphasized in this rare complication of pisotriquetral arthrosis.
