One case of internal derangement of the shoulder joint due to the proximal end of ruptured long head of the biceps tendon was reported. There have been many reports on the distal end of the long head of the biceps tendon. Pain and/or disability due to the distal end of the tendon, usually tenodesis to the bicipital groove is indicated. But, derangement due to the proximal end of the tendon has not yet been reported.The patient, a 21 year old male, had his ahoulder contused in a traffic accident. Because of his long standing (6 month) shoulder disability, he took our medical check. A procaine test was carried out to elucidate the cause of his shoulder pain and disability. The gleno-humeral joint was the site of his main lesion and subacromial impingement was the second. In double contrasted arthrography, an intraarticular abnormal band was revealed. In order to elucidate the pathology, arthroscopic examination was done. The long head of the biceps tendon was ruptured and adhered to the anterior capsule of the joint. After debridement of this tendon arthroscopically, pain and disability disappeared.
