We reported on a case which had a dislocation of the tendon of the long head of biceps (LHB) associated with isolated tear of the subscapularis tendon, and who underwent an open reduction of the LHB. In September 2001, a fortyfour-year-old-ma injured his right shoulder taking his child running in his arms. His right shoulder was forced into extension, and he had sharp pain in the front of his shoulder. Motion pain and night pain continued for a month. In October 2001, he visited our hospital. On physical examination, there were a tenderness on the lesser tuberosity and pain with a click on the bicipital groove during the Yergason test's maneuver. Active shoulder movement was not limited. Roentgenograms showed no abnormal findings. CTA and MRI showed a medial displacement of the LHB from the bicipital groove, and they showed no findings of the rotator cuff tear. In November 2001, an operation was performed. The subscapular tendon was partially torn horizontally and the LHB was dislocated inside the subscapular tendon. A reducition of the LHB and a repair of the subscapular tendon were performed. Nine months after the operation, MRIs showed effusion of the subacromial bursa, there was pain and swelling on the bicipital groove.
