Abstract: Objective To investigate the significance of clinical screening of hip joint and ultrasound examination of hip joint in the diagnosis of developmental dysplasia of the hip (DDH) and the effect of early intervention. Methods Infants under 6 months with positive hip screening results who took first physical examination in Pediatric Healthcare Clinic of Qilu Hospital (Qingdao) were enrolled in this study from July 2016 to June 2018. Children with positive ultrasound examination of type Ⅱa were given early intervention, and the positive rate of ultrasound as well as the effect of early intervention were analyzed. Results There were 1 485 infants with positive clinical screening result of the hip, including 623 males and 862 females. Ultrasound examination of the hip was positive in 174 cases, including 50 males (8.02%) and 124 females (14.39%). And 122 children with Type Ⅱa results were intervened by holding legs and padding wide diapers, of whom 117 cases (95.94%) recovered to normal status and 5 cases were referred to Pediatric Orthopaedics Department. Conclusions DDH can be detected early by clinical hip screening and ultrasound examination. Early intervention is simple, painless and has a high recovery rate.
