目的评估是否常用的手术分级量表，当应用到髋臼唇的MRI结果，可以提高术前规划和咨询患者接受hip arthroscopy.Materials和MethodsWe评估76例临床MRI进行股骨髋臼撞击患者。三名肌肉骨骼放射科医生和一名肌肉骨骼研究员以盲态方式审查了每次扫描，使用Beck量表（一种常见的手术分级量表）对髋臼唇进行了12：00至4：00的分类。通过手术检查和分类提供临床相关性。在每个时钟位置使用Cohen kappa和Krippendorff α确定阅片师之间以及阅片师和手术数据之间的可靠性，并对每次扫描进行最差分级。此外，一个简化版本的规模只包括两个等级，潜在的可修复的，不可能修复的，evaluated.ResultsWhen规模被简化成类别的潜在的可修复的，不可能修复的，灵敏度是优秀的，从85.5%到96%。当使用个体Beck分级时，观察者一致性范围从差到一般; Kappa范围从0.03到0.19，α范围从-0.27到0.22。结论当应用于MRI时，简化版本的Beck盂唇量表是潜在可修复盂唇病理的高度敏感的预测因子，同时排除正常和严重退行性组织。该量表的使用提供了临床相关信息，可以推动术前计划并改善患者咨询。它以一种标准化的方式这样做，可以在整个实践场所应用，而无需额外费用。
ObjectiveTo evaluate whether a commonly used surgical grading scale, when applied to acetabular labral findings on MRI, could improve preoperative planning and counseling for patients undergoing hip arthroscopy.Materials and methodsWe evaluated 76 clinical MRIs performed on patients with femoroacetabular impingement. Three musculoskeletal radiologists and one musculoskeletal fellow reviewed each scan in a blinded fashion, classifying the acetabular labrum from 12:00 to 4:00 using the Beck scale, a common surgical grading scale. Clinical correlation was provided via surgical examination and classification. Reliability was determined between readers and between reader and surgical data using Cohen’s kappa and Krippendorff’s alpha at each clock position and for the worst grading for each scan. In addition, a simplified version of the scale comprised of only two grades, potentially reparable and not potentially reparable, was evaluated.ResultsWhen the scale was simplified into categories of potentially reparable and not potentially reparable, the sensitivity was excellent, ranging from 85.5 to 96%. Observer agreement when using individual Beck grades was found to range from poor to fair; Kappa ranged from 0.03 to 0.19, and Alpha ranged from − 0.27 to 0.22.ConclusionThe simplified version of the Beck labral scale when applied to MRI is a highly sensitive predictor of potentially reparable labral pathology while excluding normal and grossly degenerative tissue. Use of this scale provides clinically relevant information that can drive preoperative planning and improve patient counseling. It does so in a standardized fashion that can be applied across practice sites and without additional cost.
