背景：尽管髋臼发育不良是髋关节骨性关节炎的常见病因，但由于缺乏证据，矫正手术是否有益于儿童无症状髋臼发育不良仍然存在争议。我们进行了一项纵向研究，比较同一患者的童年磁共振成像（MRI）软骨形态和成熟髋关节形态，并评估未来髋臼发育不良的预测指标。方法：对92例未受影响的髋关节（47例单侧DDH和45例单侧legg -小牛- perthes病）进行x线和MRI检查（平均年龄：6.0岁）和骨骼成熟年龄的x线检查，平均随访时间为15.1年。测量并比较以下参数：未成熟x线未成熟髋臼指数（AI）和中心边缘角（CE）；儿童MRI软骨和骨的ai、CE、Sharp和髋臼头指数（AHI）；成熟骨x线显示成熟髋臼顶倾角（ARO）、CE、Sharp和AHI。儿童髋臼发育不良的MRI预后因素，由CE定义
Background: Although acetabular dysplasia is a common etiology of osteoarthritis of the hip regardless of the history of developmental dysplasia of the hip (DDH), whether or not corrective surgeries are beneficial for the childhood asymptomatic acetabular dysplasia remains controversial due to a lack of evidence. We conducted a longitudinal study to compare the cartilaginous morphology on childhood magnetic resonance imaging (MRI) and the mature hip morphology of the same patient and to assess the predictive indicators for future acetabular dysplasia.Methods: A total of 92 unaffected hips (47 unilateral DDH and 45 unilateral Legg-Calve-Perthes disease) were reviewed for X-ray and MRI findings on childhood (mean age: 6.0 years) and X-ray findings from a skeletally mature age with a mean follow-up period of 15.1 years. The following parameters were measured and compared: the immature-acetabular index (AI) and center edge angle (CE) on immature X-ray; the cartilage- and bone-AI, CE, Sharp and acetabular head index (AHI) on childhood MRI; and the mature-acetabular roof obliquity (ARO), CE, Sharp and AHI on skeletally mature X-ray. The prognostic factors on childhood MRI for acetabular dysplasia, defined by a CE of
