Abstract: Objective To investigate the incidence of developmental hip dysplasia(DDH) among infants in Suzhou,in order to explore the clinical value of ultrasound screening in the diagnosis of DDH. Methods A total of 6 009(12 018 hips) infants suspected for DDH were selected as the participants in Soochow Municipal Hospital from January to December in 2018.All infants suspected for DDH were examined by ultrasonography,the α and β angles were measured and the category was made based on Results. Results There were 5 479 cases of normal hip joint and the incidence of DDH was 5.999%(721/12 018).The detection rate of DDH in female infants was significantly higher than that in male ones(χ²＝133.74,P<0.001).Also,the detection rate of DDH in left hips was significantly higher than that in right hips(χ²＝12.22,P=0.002). Conclusions Ultrasonic examination can assess the development of hips effectively.It can serve as a major method for early screening and follow-up of DDH in infants,and thus plays an important role in early intervention treatment.

摘要： 目的 了解苏州地区婴幼儿发育性髋关节发育不良(DDH)发生率,探讨超声筛查在幼儿DDH诊断中的临床价值。方法 2018年1-12月在苏州市立医院儿童保健科经临床检查高度怀疑DDH的6 009例,共12 018个髋关节,采用Graf高频超声技术观察婴幼儿髋关节形态,测量 α、β 角并进行分型,对结果进行统计分析。结果 本次调查正常髋关节5 479例,DDH发病率为5.999%/(721/12 018),女性DDH的检出率高于男性(χ²=133.74,P<0.001)、左侧DDH的检出率高于右侧(χ²=12.22,P=0.002)。结论 超声检查能有效地评估幼儿髋关节的发育,是婴幼儿DDH早期筛查和随访的主要手段,为早期诊断、早期治疗起到了重要作用。
