Spontaneous flexor tendon ruptures within the hand are incompletely understood. We report 5 cases of spontaneous tendon rupture involving the flexor digitorum profundus tendon. One case involves an abnormal intertendinous connection between the ring and small finger profundus tendons and another involves a lumbrical muscle variant. To our knowledge, the latter has not been reported in association with spontaneous tendon rupture. In reviewing the literature for spontaneous flexor tendon ruptures, a total of 50 spontaneous ruptures in 43 cases was found. The majority involve the profundus tendon of the small finger in the palm. The ruptures most often occur during periods of peak strain but can also occur without identifiable trauma. The pathogenesis of spontaneous tendon ruptures is still unclear and is likely multifactorial. Spontaneous flexor tendon ruptures of the hand occur more often than one might recognize.
手部自发性屈肌腱断裂的原因尚未完全明确。我们报告了5例涉及指深屈肌腱的自发性肌腱断裂病例。其中1例涉及环指和小指深肌腱之间的异常腱间连接，另1例涉及蚓状肌变异。据我们所知，后者与自发性肌腱断裂相关的情况尚未见报道。在回顾有关自发性屈肌腱断裂的文献时，共发现43例患者出现50次自发性断裂。大多数发生在手掌部的小指深肌腱。这些断裂最常发生在应变峰值期，但也可能在无明显外伤的情况下发生。自发性肌腱断裂的发病机制仍不清楚，可能是多因素的。手部自发性屈肌腱断裂的发生率比人们想象的要高。
