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.

Case summary:
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.

Conclusion:
This study describes a rare case of bilateral dislocations of the LHBT without rotator cuff injury due to dysplasia of the bicipital groove.
