Twenty-seven shoulders (in 26 patients) that had surgical repair of a rupture of the long head of the biceps tendon between 1962 and 1981 were evaluated at three to 22 years after injury (mean, 13 years). Thirty similar patients had been treated nonsurgically and were evaluated two to 15 years (mean, 4.6 years) after tendon rupture. Biomechanical testing was performed on ten patients in the surgical group and 13 in the nonsurgical group. Residual arm pain was infrequent in both surgically and nonsurgically treated groups. Residual subjective weakness at the elbow was reported in four of the surgical group and in 20 of the nonsurgical group. Surgically treated patients returned to work later than nonsurgical patients; however, 11 in the nonsurgical group were not able to return to full work capacity, versus only two in the surgical group. On biomechanical testing, the nonsurgical group had lost a mean of 21% of supination strength and 8% of elbow flexion strength but had no weakness in grip, pronation, or elbow extension. The surgical group had lost no strength in any of these testing modes.
对1962年至1981年间接受肱二头肌长头肌腱断裂手术修复的27例肩部（26例患者）在受伤后3至22年（平均13年）进行了评估。30例类似患者接受了非手术治疗，并在肌腱断裂后2至15年（平均4.6年）进行了评估。对手术组的10例患者和非手术组的13例患者进行了生物力学测试。手术治疗组和非手术治疗组残留手臂疼痛的情况均不常见。手术组有4例报告肘部残留主观无力，非手术组有20例。手术治疗的患者比非手术患者返回工作岗位的时间晚；然而，非手术组有11例无法恢复到完全工作能力，而手术组只有2例。在生物力学测试中，非手术组旋后力量平均丧失21%，肘部屈曲力量丧失8%，但握力、旋前或肘部伸展无无力。手术组在任何这些测试模式中均未丧失力量。
