Medial displacement of the tendon of the long biceps brachii muscle was analyzed in a dissection study on autopsy in 77 subjects, 42 men and 35 women. The tendon was found to be medially displaced in five shoulders in five different subjects (6.5%). Medial displacement of the tendon was always found in connection with full-thickness supraspinatus tendon ruptures. It is a common belief that the tendon is always displaced medially to the lesser tubercle riding over the subscapularis tendon. In the present series, this condition was found only in one case; in the other shoulders the tendon had slipped medially to the lesser tubercle under the subscapularis tendon, which was partially internally ruptured. In patients with rotator cuff lesions, medial displacement of the long biceps tendon might be one reason for pain over the front of the shoulder.
在一项针对77名受试者（42名男性和35名女性）尸体的解剖研究中，对肱二头肌长头肌腱的内侧移位情况进行了分析。在5名不同受试者的5个肩部中发现肌腱内侧移位（6.5%）。肌腱内侧移位总是与冈上肌腱全层断裂相关。人们普遍认为，肌腱总是向内侧移位至小结节上方，越过肩胛下肌腱。在本系列研究中，仅在1例中发现这种情况；在其他肩部，肌腱已向内侧滑至肩胛下肌腱下方的小结节处，肩胛下肌腱部分发生了内部断裂。在肩袖损伤患者中，肱二头肌长头肌腱内侧移位可能是肩部前方疼痛的原因之一。
