Medial dislocation of the long head of the biceps branchii tendon is a rare occurrence and is often associated with degenerative or traumatic tears of the rotator cuff, specifically tears of the subscapularis tendon. Following a dislocation, the biceps tendon will assume either an intra- or extra-articular position depending on whether or not the subscapularis tendon detaches from its humoral insertion. Magnetic resonance imaging (MRI) has been found to provide valuable information concerning the location of the biceps tendon and the integrity of the rotator cuff. In this report, three patients with suspected dislocations of the biceps tendon are evaluated using MRI.
肱二头肌长头肌腱内侧脱位是一种罕见情况，常与肩袖的退行性或创伤性撕裂相关，特别是肩胛下肌腱撕裂。脱位后，肱二头肌肌腱会根据肩胛下肌腱是否从其肱骨附着处脱离而处于关节内或关节外位置。已发现磁共振成像（MRI）能提供有关肱二头肌肌腱位置和肩袖完整性的有价值信息。在本报告中，使用MRI对3例疑似肱二头肌肌腱脱位的患者进行了评估。
