Cerebral palsy patients (31 hips) were evaluated using radiographic and three-dimensional (3-D) images to quantify hip anatomy. The 3-D images overcome distortions caused by joint contractures. Changes were more pronounced in the non-ambulators and characterized by shallow sockets with increased neck-shaft angles. These hips tended to subluxate in a posterior-superior direction and most had defects in the femoral heads. Ambulators had increased femoral anterversion but other hip parameters tended to improve with age. The 3-D measures of roof steepness and socket depth were found to correlate strongly with radiographic parameters of subluxation.
对脑性瘫痪患者（31个髋关节）进行了评估，采用X线摄影和三维（3-D）图像来量化髋关节解剖结构。三维图像克服了关节挛缩引起的失真。在非步行者中变化更为明显，其特征为髋臼浅平且颈干角增大。这些髋关节倾向于向后上方半脱位，且大多数股骨头存在缺陷。步行者的股骨前倾增加，但其他髋关节参数往往随年龄增长而改善。发现髋臼顶倾斜度和髋臼深度的三维测量值与半脱位的X线参数密切相关。
