Several risk factors are associated with an increased incidence of congenital hip dysplasia. Since the introduction of hip sonography the understanding of correlation between risk factors and US have been studied to decrease the prevalence of the deformity. Regression analysis and chi-square test were used to study the incidence of factors associated with congenital hip dysplasia. Positive family history, breech presentation, positive Ortolani manoeuvre, abduction deficit, asymmetric skin folds, feet or neuromuscular abnormities were compared to ultrasound examination. No significant correlation was found with any of the studied risk factors. Mild congenital hip dysplasia can be diagnosed only by ultrasound. It was found that 1.7% of congenital hip dysplasia are clinically asymptomatic and cannot be recognized without ultrasonographic screening.
多种风险因素与先天性髋关节发育不良的发病率增加相关。自引入髋关节超声检查以来，人们对风险因素与超声检查之间的相关性进行了研究，以降低该畸形的患病率。采用回归分析和卡方检验来研究与先天性髋关节发育不良相关因素的发生率。将阳性家族史、臀位分娩、奥尔托拉尼试验阳性、外展受限、皮肤褶皱不对称、足部或神经肌肉异常与超声检查结果进行比较。未发现与任何研究的风险因素有显著相关性。轻度先天性髋关节发育不良只能通过超声诊断。研究发现，1.7%的先天性髋关节发育不良在临床上无症状，未经超声筛查无法识别。
