小儿股骨头骨软骨炎分型

目的:小儿股骨头骨软骨炎骨骺变化迅速平片表现多样,如何从判断预后进行新的分型。材料和方法:2~13岁小儿60例,平均年龄8.26岁。其中2~5岁幼儿11例,6~13岁少儿49例。方法:是从股骨头骨软骨炎累及的不同范围进行分型。以简单明确、便于实用、符合发展、显示预后进行分型。结果:I型(轻)单纯骨骺坏死,骨骺碎小裂隙扁平9例(15%)。II型(中)骨骺干骺坏死,骨骺骨化不均,干骺端囊变硬化,股骨颈粗端39例(65%)。III型(重)骨骺干骺坏死加股骨头外移12例(20%)。结论:I型预后较好,髋臼发育不良者预后较坏。

Typing of childhood osteochondritis of femoral head

Objective:The epiphysis of femoral head in childhood osteochondritis changed rapidly,showing various manifestations on radiographs.It was necessary to design a new typing for predicting the prognosis.Methods: Sixty cases were studied.The age ranged from 2 to 13 years with an average of 8.26 years.Of them,11 cases aged 2~5 years and 49 cases aged 6~13 years.The typing here was according to the different extent of involvement of the disease and was simple,clear,easy to use,in keeping with development and helpful for predicting the prognosis.Results: Type I(mild), 9 cases(15%).Only epiphyseal necrosis with small leakage and mild flatness;type II(moderate),39 cases(65%).Epiphyseal and metaphyseal necrosis showing uneven epiphyseal ossification with cystic degeneration and sclerosis;thickening and shortening of femoral neck.Type III(severe),12 cases(20%).Epiphyseal and metaphyseal necrosis and lateral displacement of femoral head.Conclusion: The prognosis of type I is better.The prognosis of those with acetabular dysplasia is poor.
