摘要
目的 :通过对髋臼的影像学变化的分析 ,了解先天性及神经肌肉性原因导致的髋关节不稳。方法 :利用CT及X线平片对髋臼的改变进行评估。共研究了 2 7名儿童 ,计 3 3个不稳定髋关节。结果 :先天性髋关节发育异常儿童的关节显示了随骨盆髋臼前倾角的增大其前缘及上缘的缺损 ,在脑瘫及脊柱裂者则显示了髋臼的多方面缺损。在脑瘫患者中具有典型的后缘缺陷 ,并且是所研究群体中髋臼最浅的。结论 :髋关节不稳患儿的髋臼缺损在不同疾病的表现不同 。
Objective:By analysing the computed tomography (CT) and plain radiography change of the acetabulum,to know congenital and neuromuscular factors in hip instability.Methods:Use CT and X-ray to evaluate the acetabulum change.Thirty-three unstable hips in 27 children with congenital disease or cerebral palsy or spina bifida were studied.14 normal hips in 14 children serve as contrast.Result:Unstable hips in children with congential hip dysplasia demoustrated anterior and superior acetabulum deficiency with increased acetabulum anteversion.Global deficiency was present in acetabulum of cerebral palsy and spina bifida patients with anterior posterior and superior deficiencies.The acetabulum in cerebral palsy patients had signficant posterior deficiency and were the shallowest of groups evaluated.Conclusion:The manifest of acetabulum deficiency in unstable hip patient with different disease is different.Unstable hip patient with some deficiency is like.How to evaluate change of acetabulum deficiency is important for surgeon to operate on .
