We report ten cases of rupture of the distal part of the tendon of biceps brachii in patients aged from 27 to 58 years. MRI allowed assessment of the degree of retraction of the tendon which was related to the integrity of the bicipital expansion. When the retraction exceeded 8 cm the expansion was always ruptured. When there was doubt, or in longstanding injury, MRI allowed the lesions to be defined. Surgical repair was by reinsertion on the radial tuberosity at one or two fixation points in eight patients and reinsertion on the anterior brachial muscle in one. The other patient refused surgery. The MRI findings were confirmed at operation. Use of fixation points allowed minimal intervention, thereby reducing the risk of damaging the radial nerve. One year after operation, dynamometric evaluation of the strength of flexion and supination confirmed that the best results were obtained by reinsertion to the radial tuberosity.
我们报告了10例肱二头肌肌腱远端断裂的病例，患者年龄在27至58岁之间。磁共振成像（MRI）能够评估肌腱回缩的程度，这与肱二头肌扩张部的完整性相关。当回缩超过8厘米时，扩张部总是会断裂。当存在疑问或损伤时间较长时，MRI能够明确病变情况。8例患者通过在桡骨粗隆处的一个或两个固定点重新附着进行手术修复，1例患者在前臂肌肉上重新附着。另1例患者拒绝手术。术中证实了MRI的检查结果。使用固定点可使干预最小化，从而降低损伤桡神经的风险。术后一年，对屈肌和旋后肌力量进行测力计评估，结果证实通过重新附着于桡骨粗隆获得的效果最佳。
