摘　　要：目的量化肩峰倾斜及下垂状改变的程度并探究其对于肩峰下撞击综合征(SAIS)的相关性及诊断价值。方法对40例接受关节镜手术患者的术前肩关节核磁共振成像(MRI)(实验组)和40例健康肩关节MRI(对照组)进行量化肩峰倾斜及下垂状改变的程度分析(包括角α、β、γ、Δ、ε、ζ)。并对比各个量化指标在各组及组中的相关性及差异性,讨论其对于SAIS的诊断价值。结果病例组与对照组肩峰倾斜及下垂状改变的相关角α的独立样本t检验结果差异无统计学意义;病例组与对照组肩峰下垂及倾斜相关角β、γ、Δ、ε、ζ的独立样本t检验结果差异有统计学意义(P<0.05)。角β、γ、Δ、ε、ζ单个指标ROC结果曲线下方的区域分别为0.677、0.864、0.707、0.848、0.886,角β和角ζ联合ROC曲线下方的区域为0.906,诊断性能优异。结论肩峰倾斜及下垂状改变的相关角度对SAIS的诊断有一定价值,对于确定的量化指标角γ、ε、ζ对于SAIS具有显著性的诊断意义,而角β与ζ两者的联合诊断性能表现更加优异。Objective To quantity the degree of acromial droop tilt and explore its correlation and diagnostic value for subacromial impingement syndrome. Methods The degree of quantification of shoulder tilt and droop(including Angle α、β、γ、Δ、ε、ζ) was analyzed by preoperative MRI of 40 patients undergoing arthroscopic surgery(experimental group) and 40 healthy shoulder MRI(control group).The correlation and difference of each quantitative index in each group and group were compared to discuss their diagnostic value for rotator cuff injury and subacromial impingement syndrome. Results There was no significant difference between the patients group and the control group in the acromion droop and tilt correlation the independent sample T test of angle α(P>0.05), respectively, and the difference was statistically significant(P<0.05). The region below the ROC curve of β,γ,Δ,ε,ζ were 0.677, 0.864, 0.707, 0.848, 0.886, respectively, and the region below the ROC curve of β and ζ combined was 0.906, indicating excellent diagnostic performance. Conclusion Acromial droop and tilt correlation angle have certain value in the diagnosis of subacromial impaction syndrome. The quantitative indexes γ,ε,ζ have significant significance in the diagnosis of SAIS, and the combined diagnosis performance of β and ζ is better.
