This study compared shoulder radiographs of patients with a documented rotator cuff tear with those of asymptomatic age-matched controls. Radiographs of 40 subjects with documented rotator cuff tears were evaluated along with similar films of 84 asymptomatic age-matched controls. Three radiographs were taken of each shoulder: (1) acromioclavicular joint view, (2) anterior-posterior view with 30 degrees of external rotation, and (3) supraspinatus outlet view. Two fellowship-trained radiologists interpreted 14 radiographic areas in a blinded fashion. Inspection of the greater tuberosity showed large positive abnormal ratings for sclerosis, osteophytes, subchondral cysts, and osteolysis. No association was noted between acromial morphology and rotator cuff tears. These results indicate that shoulder radiographs of subjects with a documented rotator cuff tear have greater tuberosity radiographic abnormalities that are not noted in asymptomatic subjects without a rotator cuff tear. No relationship was found between tear length and any of the degenerative conditions.
本研究将有记录的肩袖撕裂患者的肩部X光片与年龄匹配的无症状对照者的X光片进行了比较。对40例有记录的肩袖撕裂患者的X光片以及84例年龄匹配的无症状对照者的类似X光片进行了评估。每个肩部拍摄了三张X光片：（1）肩锁关节视图，（2）外旋30度的前后视图，以及（3）冈上肌出口视图。两位经过专科培训的放射科医生以盲法解读了14个X光片区域。对大结节的检查显示，在硬化、骨赘、软骨下囊肿和骨质溶解方面有大量阳性异常评级。未发现肩峰形态与肩袖撕裂之间存在关联。这些结果表明，有记录的肩袖撕裂患者的肩部X光片显示出更大的结节X光异常，而在没有肩袖撕裂的无症状患者中未观察到这种情况。未发现撕裂长度与任何退行性病变之间存在关系。
