通过关节内髋关节异常的关节镜评价，验证术前髋关节磁共振成像（MRI）中的SHOMRI分级。39例患者40髋术前非关节造影3.0T MRI（1例患者接受双侧髋关节手术）伴股骨髋臼撞击（FAI）综合征平均年龄34.7岁± 9.0岁; n=16例女性），保守治疗无效，两名放射科医生回顾性评估接受髋关节镜检查的患者的软骨盂唇异常，并与关节内进行比较。关节镜检查结果作为参考标准。将关节镜下可触及区域与相应的SHOMRI子区域进行比较，并评估髋臼和股骨头中软骨病变的存在和分级。评估髋臼唇是否存在唇撕裂。对于统计分析，计算敏感性和特异性以及观察者间一致性的组内相关性（ICC）。关于软骨异常，58.8%的手术病例显示软骨缺陷。SHOMRI评分显示诊断软骨病变的敏感性为95.7%，特异性为84.8%。此外，所有全层缺损病例（n=9）均被正确识别，在n=6例病例（n=36例部分厚度缺损）中，识别出缺损软骨，但实际深度被高估。所有病例均存在盂唇撕裂，MR阅片员正确识别率为92.5%。ICC显示观察者间一致性良好，为86.3%（95% CI 80.0，90.6%）。使用关节镜相关性，髋关节的SHOMRI分级被证明是评估软骨盂唇髋关节异常的可靠和精确方法。
To validate SHOMRI gradings in pre-operative hip magnetic resonance imaging (MRI) with intra-arthroscopic evaluation of intraarticular hip abnormalities. Pre-operative non-arthrographic 3.0T MRI of 40 hips in 39 patients (one patient with bilateral hip surgery) with femoroacetabular impingement (FAI) syndrome (mean age, 34.7 years ± 9.0; n=16 women), refractory to conservative measures, that underwent hip arthroscopy were retrospectively assessed by two radiologists for chondrolabral abnormalities and compared to intra-arthroscopic findings as the standard of reference. Arthroscopically accessible regions were compared to the corresponding SHOMRI subregions and assessed for presence and grade of cartilaginous pathologies in the acetabulum and femoral head. The acetabular labrum was assessed for presence or absence of labral tears. For the statistical analysis sensitivity and specificity were calculated as well as intraclass correlation (ICC) for interobserver agreement. With respect to chondral abnormalities, 58.8% of the surgical cases showed chondral defects. SHOMRI scoring showed a sensitivity of 95.7% and a specificity of 84.8% in detecting cartilage lesions. Moreover, all cases with full-thickness defects (n=9) were identified correctly and in n=6 cases (out of n=36 with partial-thickness defects) the defected cartilage was identified but the actual depth overestimated. Labral tears were present in all cases and the MR readers identified 92.5% correctly. ICC showed a good interobserver agreement with 86.3% (95% CI 80.0, 90.6%) Using arthroscopic correlation, SHOMRI grading of the hip proves to be a reliable and precise method to assess chondrolabral hip joint abnormalities.
