Avulsion of the flexor tendon

This injury is caused by sudden hyperextension of the distal joint, typically when a game player catches his finger on an opponent’s shirt. The ring finger is most commonly affected. The flexor digitorum profundus tendon is avulsed, either rupturing the tendon itself or taking a fragment of bone with it. If the bone fragment is small, or if only the tendon is ruptured, it can recoil into the palm. If the lesion is detected within a few days (and the diagnosis is easily missed if not thought about), then the tendon can be re-attached.

If the diagnosis is much delayed, repair is likely to be unsuccessful. Two-stage tendon reconstruction is possible but difficult, and the finger may end up stiff. Thus, for late cases, tenodesis or fusion of the distal joint is usually preferable.

屈肌腱撕脱

这种损伤是由远端关节突然过度伸展引起的，通常是当游戏玩家的手指碰到对手的衬衫时。无名指最常受到影响。指深屈肌肌腱撕裂，或是肌腱本身断裂，或是带着一块骨头碎片。如果骨头碎片很小，或者只有肌腱断裂，它会反冲到手掌中。如果在几天内发现病变（如果不考虑的话很容易漏诊），那么肌腱可以重新附着。

如果诊断耽搁太久，修理很可能不成功。两阶段肌腱重建是可能的，但困难，手指可能最终僵硬。因此，对于晚期病例，肌腱松解或远端关节融合通常更为可取。
