先天性髋关节脱位的早期X线诊断

Early Diagnosis of Neonatal Congenital Hipjoint Dislacation by X-ray

目的 探讨新生儿先天性髋关节脱位的Ｘ 线诊断方法；方法 ２１ 例先天性髋关节脱位新生儿的３０ 个患髋及１３０ 例正常小儿的新生儿期骨盆片，均经一年随访证实，将２１ 例患儿的３０ 个患髋与１３０ 例正常新生儿的２６０ 个正常髋关节进行测量对比分析；结果 ３０ 个患髋中，髋臼呈平直线状２８ 个髋，闭孔线示脱位阳性２７ 髋，髋臼指数大于３６°者６ 髋；２６０ 个正常髋关节中，髋臼呈平直线状２２８ 髋，髋臼指数大于３６°者７ 髋，闭孔线示阳性者９ 髋；结论 闭孔线、髋臼指数、股骨颈轴线及Ｒｏｓｅｎ 线作为先天性髋关节脱位的早期诊断方法是可靠的。

Objective To study on early diagnosis of neonatal congenital dislacation of new-born. Methods 21 cases of NCDH in 30 hip lesions and 130 cases with normal films of pelvic in the control group were followed up for a year.30 hip lesions in 20 cases and 260 normal hips in 130 cases were measured,contrasted and analysed.Results Among 30 hips, 28 films acetumen showed level line,27 hip dislocation by line of obturator foramen.The acetabular index in 6 hip lesions >36°.In 260 normal hipjonts 228 showed level in acetabulum, 7 normal hips' acetabular index >36°,line of obturator foramen showed hip dislocation in 9 cases.Conclusion The X-ray films of line of obturator foramen,acetabular index and line of Rosen are reliable to early diagnosis of neonatal congenital hipjoint dislacation.
