摘　　要：目的 探讨X线片测量肱骨大结节角(GTA)与肩袖撕裂的相关性,为肩袖撕裂的预防、早期诊断和治疗提供依据和指导。方法 回顾性分析2020年1月至2023年12月医院收治的138例因肩部疼痛不适行肩部X线检查患者的病历资料。根据临床诊断结果将发生肩袖撕裂的患者纳入试验组(64例),未发生肩袖撕裂的患者纳入对照组(74例)。比较两组GTA的差异;考察GTA预测肩袖撕裂的临界值和预测能力;评价2名放射科医师测量结果的一致性和相关性。结果 试验组GTA大于对照组,差异有统计学意义(P<0.05)。区分试验组与对照组患者的GTA最佳临界值为≥70°,受试者工作特征(ROC)曲线下面积为0.826,灵敏度和特异度分别为0.88和0.81。2名放射科医师测量GTA结果的组内相关系数(ICC)为0.677,Pearson’s相关性系数r=0.547。结论 采用X线片测量GTA对肩袖撕裂具有较好的预测价值和较高的测量一致性,可为肩袖撕裂的预防、早期诊断和治疗提供依据和指导。Objective To explore the correlation between the greater tuberosity angle(GTA) of the humerus and rotator cuff tear,and provide basis and guidance for the prevention,early diagnosis,and treatment of rotator cuff tear.Methods With the retrospective analysis of the medical records of 138 patients who underwent shoulder X-ray examinations in the radiology department of the hospital from January 2020 to December 2023due to shoulder pain and discomfort,according to clinical diagnosis,patients with rotator cuff tears were included in the rotator cuff experimental group(64 cases),while patients without rotator cuff tears were included in the control group(74 cases).The GTA results of each patient were independently measured by two radiologists,and the average was taken for statistical analysis.With the comparison of the differences of GTA between the two groups,the critical value and predictive ability of GTA for predicting rotator cuff tears were examined,and the consistency and correlation of the measurement results of two radiologists were evaluated.Results The GTA of the rotator cuff experimental group was higher than that of the control group,and the difference was statistically significant(P<0.05).The optimal critical value of GTA for distinguishing between the rotator cuff experimental group and the control group patients was ≥70°,with the area under receiver operating characteristic(ROC) curve of 0.826,sensitivity and specificity of 0.88and 0.81,respectively.The intra-class correlation coefficient(ICC) of GTA results measured by two radiologists was 0.677,and Pearson's correlation coefficient r= 0.547.Conclusion GTA for rotator cuff tear has good predictive value and higher measurement consistency,providing basis and guidance for the prevention,early diagnosis,and treatment of rotator cuff tears.
