Abstract：
BACKGROUND: Dislocation of the long head of biceps tendon (LHBT) usually involves rotator cuff injury, and isolated dislocation with an intact rotator cuff is rare. Some cases of isolated dislocation have been reported. However, to the best of our knowledge, there has been no report of bilateral dislocation of the LHBT without rotator cuff pathology.
METHODS: A 23-year-old male presented to our outpatient clinic with left side dominant pain in both shoulders. The patient had no history of trauma or overuse. The patient underwent intra-articular injection and physical therapy, but his symptoms aggravated. Based on preoperative imaging, the diagnosis was bilateral dislocation of the LHBT. Dysplasia of the bicipital groove was detected in both shoulders. Active dislocation of the biceps tendon over an intact subscapularis tendon was identified by diagnostic arthroscopy. Staged biceps tenodesis was performed and continuous passive motion therapy was administered immediately after surgery. The patient\'s pain was resolved, and full functional recovery was achieved, and he was satisfied with the condition of his shoulders.
CONCLUSIONS: This study describes a rare case of bilateral dislocations of the LHBT without rotator cuff injury due to dysplasia of the bicipital groove.

摘要：
背景：二头肌肌腱（LHBT）长头脱位通常涉及肩袖损伤，孤立的脱位与完整的肩袖是罕见的。已经报道了一些孤立的脱位病例。然而,据我们所知,没有无肩袖病变的LHBT双侧脱位的报道.
方法：一名23岁的男性出现在我们的门诊，双肩左侧显性疼痛。患者无外伤或过度使用史。患者接受了关节内注射和物理治疗,但他的症状加重了.根据术前影像学,诊断为双侧LHBT脱位。在双肩中检测到二头肌沟发育不良。通过诊断性关节镜检查确定了肱二头肌腱在完整的肩胛骨下肌腱上的主动脱位。手术后立即进行了阶段性的肱二头肌肌腱固定术，并进行了连续的被动运动治疗。病人的痛苦得到了解决，并实现了完整的功能恢复，他对肩膀的状况感到满意。
结论：本研究描述了一例罕见的LHBT双侧脱位，但由于二头沟发育不良导致肩袖损伤。
