Forty-one hips in 24 patients with neuromuscular disease (NMD) were studied using three-dimensional computed tomography (3DCT). The location of the acetabular deficiency was posterior (37%), anterior (29%), midsuperior (15%), and mixed (19%) (anterosuperior, posterosuperior, and global). Although subtle morphologic changes occurred in the entire acetabulum, the major acetabular deficiency coincided with the direction of the subluxation or dislocation. The location of the acetabular deficiency that develops in cerebral palsy is not always posterosuperior, as suggested by other authors. The pattern of spasticity that results in muscle imbalance around the hip joint and changes in proximal femur architecture causes hip subluxation or dislocation, which may be either, posterior, anterior, or midsuperior. 3DCT studies are required to analyze accurately and understand acetabular deficiency in childhood NMD. These image data also allow more accurate planning for surgery in neuromuscular hip dysplasia.
对24例患有神经肌肉疾病（NMD）患者的41个髋关节进行了三维计算机断层扫描（3DCT）研究。髋臼发育不良的位置为后方（37%）、前方（29%）、中上（15%）和混合型（19%）（前上、后上和整体型）。虽然整个髋臼出现了细微的形态学变化，但主要的髋臼发育不良与半脱位或脱位方向一致。脑瘫患者中出现的髋臼发育不良位置并不总是如其他作者所指出的后上方。导致髋关节周围肌肉失衡和股骨近端结构改变的痉挛模式会引起髋关节半脱位或脱位，其方向可能是后方、前方或中上。需要进行3DCT研究以准确分析和理解儿童NMD中的髋臼发育不良。这些图像数据也有助于更准确地规划神经肌肉性髋关节发育不良的手术。
