Biceps tendon dislocation combined with rupture of subscapularis tendon is not a common lesion and there has been few case reported in Korea. We experienced one fifty Six years old male patient who shows typical features on physical examination and roentgenographic finding. He was injured by direct trauma on his right shoulder in adducted and external rotated position. He showed positive findings on passive external rotation test and lift-off test. On MR!, the subscpaularis tendon was totally ruptured and the biceps tendon was dislocated to anteromedial aspect of the glenoid labrum, which was typical finding. On the arthroscopic examination, the subscapularis tendon was totally ruptured from its humeral attachment and the biceps tendon was not seen in its normal anatomical position and it was dislocated antermedially to the glenoid labrum. We repaired the subscapularis tendon to humerus by use of suture anchor and the biceps tendon was relocated to its normal anatomical position in the intertubercular groove. On the post operative 6 months follow up, the patient shows improvements in his subjective symptoms and active range of motion.
