Abstract: Objective To analyze the most appropriate method for the diagnosis of developmental dysplasia of the hip (DDH),thereby making it possible to treat DDH earlier and achieve good prognoses by assessing the role of clinical examinations,ultrasonic (US) examination and associated risk factors in infants with DDH. Method Totally 139 infants hospitalized in the NICU of the first affiliated hospital of Shantou University Medical College from November 2014 to November 2015 were involved.Clinical data and Results of physical examinations and US examinations of the hips were collected,and followed up according to the results.Several risk factors which may affect hip development were analyzed. Results 1)Among 139 infants,83 (59.7%) had abnormal US examinations,in which 6 were Graf type Ⅱc and one (0.7%) was eventually diagnosed as hip dislocation.2)The study showed higher prevalence of DDH in left side hip than the right ride (OR=1.863,P<0.05) and in breech presentation (OR=4.063,P<0.05).3)Compared with US results,clinical examination had a sensitivity of 42.1% and specificity of 66.1%.4) Gender,gestational age,delivery mode,amniotic fluid volume and PE Results did not have significant difference in DDH prevalence. Conclusions To detect DDH,US examination is necessary and important since the sensitivity and specificity of clinical examinations are quite low.The left side hip and breech presentation are significantly associated with DDH.Most Graf type Ⅱa hips and some Graf type Ⅱc hips resolve spontaneously at the age of 3~6 months,but close follow-up is recommended.
