[Purpose]The present study was undertaken to elucidate the pathological conditions of both the capsule and subacromial bursa of contracted shoulders associated with rotator cuff tears.[Materials and methods]Twenty-six shoulders of 26 patients,22 males and 4 females, aged from 37to 75 years old (mean 57) received brisement procedures prior to cuff surgeries. There were 8 large,12 small and 6 partial thickness tears. Arthroscopic observation was done to find out the site of the capsular injury after the brisement procedures. Macroscopic observation of torn cuffs and the adhesion of the bursa were also performed.[Results]Arthroscopic findings after brisement procedures revealed redness, proliferations, and bleeding of the synovium in the glenohumeral joint. There were two types of capsular injuries. TypeA: tear of the axillar region(17 shoulders), Type B: tear of the axillar and rotator interval regions(9 shoulders). The number of cases of (Type A: Type B) was (7: 1) with large tears, (6: 6) with small tears and (4: 2) with partial thickness tears. If cuff tears included the rupture of the anterior band of the supraspinatus tendon, the number of (Type A: Type B) was (12: 3), while it was (1: 4) without a rupture of the band. Although there were adhesions between the bursa and cuff in 85% shoulders, no disruptions were found in the subacromial bursae.[Conclusion]The main cause of a shoulder contracture assosiated with rotator cuff tears was located at the axillar and rotator interval capsules and was influenced by the size of the location and cuff tears.
