A review of 36 avulsions of the flexor profundus tendon insertion in athletes seen during the past 5 years showed the injury to be most common in the ring finger. The injury was classified into three types depending upon (1) the presence or absence of a bony fragment on roentgenograms, (2) the level to which the tendon retracted, and (3) the status of the blood supply of the avulsed tendon. If the tendon retracts into the palm at the time of injury, it should be repaired within 7 days. If the tendon retracts only to the proximal interphalangeal joint, it often can be repaired a few months after the injury. Late untreated patients who were relatively asymptomatic were left alone. Those with unstable distal interphalangeal joints were treated by fusion or tenodesis of the distal joint. A flexor tendon graft through an intact functioning superficialis tendon in the ring finger seldom was indicated. Prompt diagnosis and surgical repair within the first week gave the best results.
对过去5年中见到的36例运动员指深屈肌腱止点撕脱伤的回顾显示，该损伤在环指最为常见。根据以下情况将损伤分为三种类型：（1）X线片上有无骨块；（2）肌腱回缩的程度；（3）撕脱肌腱的血供情况。如果损伤时肌腱回缩至手掌，应在7天内进行修复。如果肌腱仅回缩至近端指间关节，通常可在损伤后数月进行修复。相对无症状的未治疗晚期患者可不予处理。远端指间关节不稳定的患者则通过远端关节融合或腱固定术进行治疗。很少需要通过环指完整且功能正常的指浅屈肌腱进行屈肌腱移植。在第一周内进行及时诊断和手术修复可取得最佳效果。
