为了探讨臀肌挛缩对小儿身体发育的影响。对１４例不对称臀肌挛缩和２４例８～９岁对称性臀肌挛缩患儿进行体检及骨盆和髋关节Ｘ线测量。不对称性臀肌挛缩组行自身对照研究（ｔ检验），对称性臀肌挛缩患儿按病程及病情分为４组，按析因试验的设计行方差分析。发现１４例不对称性臀肌挛缩患儿臀肌挛缩对股骨颈干角、股骨头骺商及髋臼商无影响（Ｐ＞０．２），而髂骨的高宽比值和双侧髋臼指数变小（Ｐ＜０．０５），２４名对称性臀肌挛缩患儿检查显示，病程及病情均为影响因素（Ｐ＜０．０５），但二者间无交互作用（Ｐ＜０．８）。此外，臀肌挛缩对脊柱等结构发育尚有影响。臀肌挛缩可影响小儿身体发育，尤其是髂骨及髋臼的发育，病情越重或病程越长影响越明显。
In order to investigate the gluteal muscle contracture on the impact of physical development in children. 14 cases of asymmetric gluteal muscle contracture and 24 cases of 8 to 9 years old with symmetrical gluteal muscle contracture in children with physical examination and pelvis and hip X-ray measurements. Asymmetrical gluteal muscle contracture group self-control study (t test), symmetrical gluteal muscle contracture in children by course of disease and disease are divided into 4 groups, according to the design of factorial analysis of variance analysis. Found that 14 cases of gluteal muscle contracture in children with gluteal muscle contracture on the femoral neck, femoral head epiphyseal business and acetabular quotient had no effect (P> 0.2), while the ratio of the ilium and bilateral acetabulum (P <0.05). The examination of 24 children with symmetrical gluteal muscle contracture showed that the course of the disease and the disease were the influencing factors (P <0.05), but there was no interaction between them (P <0.05). 8). In addition, gluteal muscle contracture on the structural development of the spine and other still have an impact. Gluteal muscle contracture can affect children’s physical development, especially the development of the ilium and acetabulum, the more serious the disease or the longer the impact of the more obvious.
