Abstract:
[Objective]To investigate the morphological changes of the roof of the subacromial bursa and the extent of involvement of the subacromial bursa after rotator cuff tear.[Method]For the experimental group,the roof of the subacromial bursa was obtained from patients with rotator cuff tear both at the tear site and 2.5 to 3.0 cm distal to the tear site during surgery of rotator cuff repair.For the control group,the roof of the subacromial bursa was obtained during surgery of recurrent shoulder dislocation or humeral shaft fracture at the exposure site.The specimens were processed for histological staining,immunohistochemical analysis and for transmission electron microscopy.The number of cells were quantitated by counting cells with blue-stained nucleus in the subacromial bursa using a computer image analysis system.[Result]The number of cells increased significantly in the roof of the subacromial bursa obtained from both sites,the tear site and the distal site,in the patients with rotator cuff tear,compared with the normal bursa(P
