Tendon ruptures in the hand without previous direct trauma are rare. Two cases are reported on with attrition of the flexor pollicis longus tendon. The first tendon rupture was along a dislocated cortico-cancellous bone graft following a Matti-Russe procedure; the second was by attrition over the screw of an AO-plate following internal fixation in scaphoid nonunion. Immediate tendon repair by interposition of a short tendon graft or by transposition of the superficialis flexor tendon of the ring finger is the treatment of choice. Further tendon ruptures can arise if surgical intervention is delayed.
手部肌腱在无既往直接创伤情况下发生断裂较为罕见。本文报告两例拇长屈肌腱磨损断裂的病例。第一例肌腱断裂发生在Matti-Russe手术后，沿着移位的皮质松质骨移植块；第二例是在舟骨不愈合内固定后，因AO钢板螺钉处的磨损导致。首选治疗方法是通过植入短肌腱移植或转位示指浅屈肌腱进行即时肌腱修复。如果手术干预延迟，可能会发生进一步的肌腱断裂。
