Abstract: Objective To learn the hip development of infants within six months in Xinjiang Ili state and the detection rate of ultrasonography in infant developmental dysplasia of hip(DDH),investigate the epidemic factors of DDH and provide guidance for early interference. Methods From April,2011 to April,2012,1 862 infants within six months in our hospital(totaling 3 724 hips) were examined by regular physical examination and ultrasound screening.The epidemic factors of DDH were studied and at the same time,the exceptional cases were intervened with individualized treatment. Results 37 exceptional cases of hip dysplasia were examined by ultrasound screening(totaling 50 hips),with a 1.3% DDH detection rate.The incidence rate of baby girls was higher than that of baby boys,in a proportion of 2 to 1.The DDH detection rate of Kazak and Uyghur nationality was significantly higher than that of Hui and Han nationality (4∶1).All the patients of various types recovered after timely and individualized treatment. Conclusion DDH morbidity varies with different gender and nationality.Babies whose legs are wrapped after birth tend to have hip dysplasia.Earlier screening for infant hip development can prevent against pathogenic factors thus will have great significance on earlier individualized intervention treatment.

Key words: hip dysplasia, earlier screening, intervention, infants

摘要： 目的 了解伊犁州6个月内婴儿髋关节发育状况和超声筛查发育性髋关节发育不良(developmental dysplasia of hip,DDH)检出率,探讨DDH发病相关因素,为早期干预提供依据。方法 对2011年4月-2012年4月在本院儿保科体检的6个月内婴儿1 862例(共计髋关节3 724个)进行常规髋关节物理检查和超声筛查,并对DDH相关因素进行流行病学调查,同时对筛查检出的异常病例积极个体化干预治疗。结果 超声筛查出髋关节异常37例(共计50个髋关节),DDH检出率为1.3%,女婴发生率高于男婴,比例为2∶1,哈萨克族、维吾尔族DDH检出率明显高于回族、汉族(4∶1);对不同类型病例积极采取个体化治疗后,均恢复正常。结论 不同性别、民族DDH检出率不同,出后双下肢包裹的婴儿易发生髋关节发育不良;开展婴幼儿DDH早期筛查,对不利因素早期干预,并对DDH患儿进行早期个体化干预治疗具有重要的意义。
