背景：肩袖疾病的病因是与年龄有关的，正如患病率数据所证明的那样。尽管结果相互矛盾，但越来越多的证据表明，不同的肩胛骨形态可能会加速潜在的退行性过程。本研究的目的是评估5种常用的肩胛骨形态的放射学参数的预测能力，以区分患者与完整的肩袖肌腱和撕裂的肩袖tenders.Methods：一个预先的功率分析进行，以确定样本量。两名独立的阅片员在标准化的前后位X线片上测量肩峰指数、肩峰外侧角和临界肩角。此外，根据Bigliani的肩峰形态和肩峰斜率在真实出口视图上确定。对51例有记录的退行性肩袖撕裂的连续患者和年龄和性别匹配的51例肩袖肌腱完整患者的对照组进行了测量。受试者操作特征分析，以确定截止值，并评估每个参数的敏感性和特异性。结果：退行性肩袖撕裂的患者表现出显着较高的肩峰指数，较小的肩峰外侧角，较大的临界肩关节角度与完整的肩袖患者。然而，根据Bigliani的肩峰形态和肩峰斜率之间没有差异。接受者工作特征曲线下的面积为0.855，比值比为10.8，临界肩角代表了最强的预测肩袖tear.Conclusion的存在：肩峰指数，肩峰外角，临界肩角准确预测存在退行性肩袖撕裂。(C)2014年《肩肘外科杂志》董事会。
Background: The etiology of rotator cuff disease is age related, as documented by prevalence data. Despite conflicting results, growing evidence suggests that distinct scapular morphologies may accelerate the underlying degenerative process. The purpose of the present study was to evaluate the predictive power of 5 commonly used radiologic parameters of scapular morphology to discriminate between patients with intact rotator cuff tendons and those with torn rotator cuff tendons.Methods: A pre hoc power analysis was performed to determine the sample size. Two independent readers measured the acromion index, lateral acromion angle, and critical shoulder angle on standardized anteroposterior radiographs. In addition, the acromial morphology according to Bigliani and the acromial slope were determined on true outlet views. Measurements were performed in 51 consecutive patients with documented degenerative rotator cuff tears and in an age-and sex-matched control group of 51 patients with intact rotator cuff tendons. Receiver operating characteristic analyses were performed to determine cutoff values and to assess the sensitivity and specificity of each parameter.Results: Patients with degenerative rotator cuff tears demonstrated significantly higher acromion indices, smaller lateral acromion angles, and larger critical shoulder angles than patients with intact rotator cuffs. However, no difference was found between the acromial morphology according to Bigliani and the acromial slope. With an area under the receiver operating characteristic curve of 0.855 and an odds ratio of 10.8, the critical shoulder angle represented the strongest predictor for the presence of a rotator cuff tear.Conclusion: The acromion index, lateral acromion angle, and critical shoulder angle accurately predict the presence of degenerative rotator cuff tears.
