Subcutaneous rupture of the short head tendon of the biceps brachii is a very rare lesion, with only five cases previously reported. The case of a 67-year-old farmer whose tendon ruptured following a mild muscle effort is presented. The degenerative changes revealed by histological examination of the injured tendon were so severe as to lead to the conclusion that its tensile strength must have fallen considerably prior to rupture. The most characteristic clinical signs of this rupture are a sizeable bulge in the middle third of the injured arm, and a hollow in the site normally occupied by the short head of the biceps. Suture of the ruptured tendon to that of the coracobrachialis led to full functional recovery.
肱二头肌短头肌腱皮下断裂是一种非常罕见的损伤，此前仅报道过5例。本文介绍了一名67岁农民的病例，其肌腱在轻度肌肉用力后发生断裂。对受伤肌腱进行组织学检查发现的退行性改变非常严重，以至于得出结论：其抗张强度在断裂前必定已大幅下降。这种断裂最典型的临床体征是受伤手臂中段出现明显隆起，以及肱二头肌短头正常所在部位出现凹陷。将断裂的肌腱与喙肱肌肌腱缝合后，功能完全恢复。
