小儿发育性髋关节脱位不同年龄股骨颈前倾角变化的分析

Analysis of the changes of the femoral neck anterior inclination of different age in children with developmental hip dislocation

目的:分析小儿发育性髋关节脱位不同年龄股骨颈前倾角的变化。方法:收治发育性髋关节脱位患儿600例,对比患侧与健侧股骨颈前倾角,分析股骨颈前倾角变化情况与年龄的关系。结果:同一年龄段患儿健侧的股骨颈前倾角会比患侧小(P<0.05);4岁以前,股骨颈前倾角会先减小后增大,变化速度较快;4岁之后,股骨颈前倾角呈稳定增大趋势,变化速度变缓。结论:发育性髋关节脱位患儿的股骨颈前倾角与年龄具有一定的关系。

Objective:To analyze the changes of the femoral neck anterior inclination of different age in children with developmental hip dislocation.Methods:600 children with developmental hip dislocation were selected.The femoral neck anterior inclinations of the affected side and the contralateral side were compared.The relationship between the change of the femoral neck anterior inclination and age was analyzed.Results:At the same age,the femoral neck anterior inclination of the contralateral side was small than that of the affected side(P<0.05).Before 4 years old,the femoral neck anterior inclination would decreases first and then increases,and the change was fast.After 4 years old,the femoral neck anterior inclination showed a steady increase trend,and the change was slow.Conclusion:The femoral neck anterior inclination of children with developmental hip dislocation has a certain relationship with age.
