Abstract

The pathomechanism of the shoulder rotator cuff tear has being under debate. Two main theories of the pathogenesis of the disease consist of mechanical (extrinsic) and degenerative (intrinsic) theories. The purpose of this work was to evaluate the chronic rotator cuff tear related to pathology as symptom and recovery after surgery, radiological diagnosis and histopathology of subacromial bursa, and subacromial mechanical pressures in 40 patients. Variation in the shape of the acromion, identified in 40 patients by a routine supraspinatus outlet view and magnetic resonance imaging were related with chronic rotator cuff tear. The role of subacromial bursa in rotator cuff tear also has been studied among the patients. The postoperative results measured by the modified UCLA shoulder rating scale. Nine of the 20 shoulders were rated excellent, 10 good, 6 fair and 4 poor results. Overall, 30 of the 40 patients rated as satisfactory results and returned to work activities. The preoperative symptoms of the patients were closely related to the synovial hyperplasia of the subacromial bursa and acromial shape and the postoperative results were related to the fibrosis of the bursa. Based on this study, both extrinsic mechanical and intrinsic degenerative factors were involved in the symptom and prognosis of chronic rotator cuff tears.
