臀肌挛缩对小儿身体发育的影响

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。

Effects of Gluteal Contracture on Physical Development of Children.

A survey of physical examination,pelvic and hip joint x-ray films of forteen cases of unilateral and 24 of bilateral gluteal contracture was made.For the unilateral contracture group,t-test to self-control design was selected.According to the extent and duration the bilateral contracture group was divided into 4 subgroups.An analysis of variance of factorial design was selected.The evaluation of unilateral group showed that the acetabular quotient,epiphyseal quotient of femoral head,and the neck-shaft angle were not affected(P>0.2),but the height-width ratio of the ilium and acetabular index reduced(P<0.05).Both the extent and duration of the contracture were affecting factors(P<0.05)in the bilateral group,Forthermore,other structures such as the spines were also affected.It is concluded that gluteal contracture is harmful to the physique and development of acetahtilar and ilium.The more extensive the contracture or the longer the duration,the worse the effects will be.
