摘要
目的 观察发育性髋关节发育不良（ＤＤＨ） 治疗后股骨头同心复位、髋臼发育的情况，预测髋臼的发育。方法 应用ｃ／ｂ 比率和髋臼指数（ＡＩ） 对４ 个月～５ 岁的１５１ 例单侧ＤＤＨ治疗后与健侧髋关节进行对比观察。结果 治疗后患侧髋臼发育的速度１ 年内最快，１ ～３ 年较快，以后逐渐减慢；健侧髋臼发育此特征不明显。结论 ｃ／ｂ 比率和ＡＩ能很好地提示髋臼发育不良治疗后的发育。
Objective To observe the effects of concentric reduction and acetabular development after the treatment of the DDH for the prediction of acetabular development. Methods c/b rate and acetabular index(AI) of 151 DDH patients were contrasted,observed and followed up. Results The speed of the acetabular development after treatment was the fastest within one year,faster one 1～3 years, and gradually became slow afterwords. The acetabular development of healthy limb did not change evidently. Conclusion c/b rate and AI can well reflect the prognosis of acetabular hypoplasia after treatment.
