To measure muscular strength after rupture of the long head of the biceps brachii, we evaluated ten patients treated conservatively and five surgically with the Cybex II testing machine, and compared the values with the data on 20 healthy individuals. In the conservative group, the strength of elbow flexion was diminished by 16%, of supination of the forearm by 11%, and of shoulder abduction by 16%. The patients who underwent surgery lost, on average, only 8% strength for elbow flexion and 7% for forearm supination. Shoulder abduction was decreased by 20%. A moderate advantage was thus found for elbow flexion and forearm supination. Surgical treatment can be recommended for younger individuals, manual workers, and sportsmen, and rarely for cosmetic reasons, or when a subacromial impingement due to a disturbing proximal tendon stump is present.
为了测量肱二头肌长头肌腱断裂后的肌肉力量，我们使用Cybex II测试机对10例接受保守治疗的患者和5例接受手术治疗的患者进行了评估，并将这些值与20名健康个体的数据进行了比较。在保守治疗组中，肘关节屈曲力量下降了16%，前臂旋后力量下降了11%，肩关节外展力量下降了16%。接受手术的患者，肘关节屈曲力量平均仅损失8%，前臂旋后力量损失7%。肩关节外展力量下降了20%。因此，在肘关节屈曲和前臂旋后方面发现了适度的优势。对于年轻个体、体力劳动者和运动员，可推荐手术治疗，很少因美容原因或存在因近端肌腱残端干扰导致的肩峰下撞击而进行手术。
