摘　　要：目的:探讨国人肩峰指数(acromion index,AI)与肩袖撕裂的关系。方法:收集130例确诊为肩袖全层撕裂患者(肩袖撕裂组)和70例肩袖完整者(肩袖完整组)的病例资料。在肩关节正位X线片上测定研究对象的AI,并根据肩袖撕裂的程度将肩袖撕裂分为小型、中型、大型和巨大型,分析AI与肩袖撕裂的关系。结果:肩袖撕裂组AI高于肩袖完整组(0.73±0.06,0.67±0.07,t=6.524,P=0.000)。在130例肩袖撕裂患者中,小型肩袖撕裂15例、中型肩袖撕裂63例、大型肩袖撕裂38例、巨大型肩袖撕裂14例;4种类型肩袖撕裂患者的AI比较,差异无统计学意义(0.73±0.07,0.73±0.06,0.73±0.06,0.75±0.08,F=0.529,P=0.663);肩袖撕裂程度与AI之间不存在直线相关关系(r=0.067,P=0.451)。经受试者工作特征曲线分析,采用AI诊断肩袖撕裂的准确性中等(Az=0.75,P=0.000);最佳诊断分界点为0.70,对应的灵敏度和特异度分别为0.70和0.67。结论:在国内人群中可以应用AI诊断肩袖撕裂,AI诊断肩袖撕裂的最佳诊断分界点为0.70;肩袖损伤的程度与AI不存在直线相关关系。Objective:To explore the relationship between acromion index(AI)and rotator cuff tear in Chinese.Methods:The medical records of 130 patients with full-thickness rotator cuff tears(rotator cuff tear group)and 70 patients with intact rotator cuff(rotator cuff integrity group)were collected.The AI of patients were measured on anteroposterior X-ray films of shoulder joint.The rotator cuff tears were divided into small-,medium-,large-and huge-sized type according to the degree of rotator cuff tear,and the relationship between AI and rotator cuff tear were analyzed.Results:The AI was higher in rotator cuff tear group compared to rotator cuff integrity group(0.73+/-0.06 vs 0.67+/-0.07,t=6.524,P=0.000).The rotator cuff tear of the 130 patients included small-sized(15),medium-sized(63),large-sized(38)and huge-sized(14)rotator cuff tears.There was no statistical difference in AI between the 4 groups of rotator cuff tears(0.73+/-0.07,0.73+/-0.06,0.73+/-0.06,0.75+/-0.08,F=0.529,P=0.663).There was no linear correlation between the degree of rotator cuff tear and AI(r=0.067,P=0.451).The result of receiver operator characteristic curve(ROC)analysis showed that AI had moderate accuracy of measurement in diagnosing rotator cuff tear(Az=0.75,P=0.000),and the optimum diagnostic cutoff point was 0.70,and the corresponding sensitivity and specificity were 0.70 and 0.67 respectively.Conclusion:AI can be used for diagnosing rotator cuff tear in Chinese,and the optimum diagnostic cutoff point of AI was 0.70.There is no linear correlation between the degree of rotator cuff injury and AI
