Hip dysplasia is an important cause of osteoarthrosis of the hip, especially in Japanese. Recently, the role of the acetabular labrum in hip diseases has attracted the attention of researchers, but the condition of the labrum in the dysplastic hips has not been described. We used radial MRI to measure the degree of coverage of the femoral head by the acetabulum and the labrum, corresponding to 7 positions on the acetabular rim at every 15 degrees from anterosuperior 45 degrees via midsuperior to posterosuperior 45 degrees. 38 Japanese patients (51 hips) with dysplasia, and 11 healthy controls 122 hips) were studied. In the dysplastic hips, the labrum was larger than in the controls. We found no correlation between the coverage of the acetabulum in the anterosuperior positions and the size of the labrum among the dysplastic hips.
髋关节发育不良是髋关节骨关节炎的一个重要原因，在日本人中尤为如此。最近，髋臼盂唇在髋关节疾病中的作用引起了研究人员的关注，但发育不良髋关节中盂唇的状况尚未得到描述。我们使用径向磁共振成像（MRI）测量髋臼和盂唇对股骨头的覆盖程度，对应髋臼边缘上从45度前上方向经正上方向到45度后上方每隔15度的7个位置。对38例日本发育不良患者（51个髋关节）和11名健康对照者（122个髋关节）进行了研究。在发育不良的髋关节中，盂唇比对照组的更大。我们发现在发育不良的髋关节中，前上方位置的髋臼覆盖度与盂唇大小之间没有相关性。
