RESUMEN
Three cases of rupture of a flexor tendon graft many years after surgery are presented. Two cases occurred 12 years after reconstruction and the third case occurred 21 years after reconstruction. Each rupture was intratendinous, just proximal to the flexor tendon sheath in 2 cases and at the proximal edge of the transverse carpal ligament in the third case. Active digital flexion was restored by transfer of the flexor digitorum superficialis from an adjacent finger to the distal tendon stump or by direct end-to-end repair of the rupture site reinforced with an onlay autogenous patch graft. Patients undergoing tendon grafting should be alerted to the possibility of rupture, even many years later.

In the past several years, the role of MR imaging in diagnosing pathologic conditions of the elbow has dramatically increased. Aside from imaging soft-tissue tumors, it can accurately visualize partial and complete tears of tendons and ligaments, as well as displacement of epiphyseal fractures in children. Its role in identifying loose bodies, particularly when they are nonosseous, and areas of osteochondritis dissecans has also increased. The use of MR imaging for diagnosing neuropathies, particularly when electrodiagnostic studies are negative, offers exciting possibilities as additional technical improvements are developed.

Isolated dislocation of the carpometacarpal joint of the index finger is a rare injury. This paper reports a case of an isolated dorsal dislocation of the second carpometacarpal joint not reducible by closed means. At open reduction, the extensor carpi radialis brevis was found to be interposed in the joint, blocking reduction.
