Epidemiology
Estimates of the prevalence of developmental dysplasia of the hip (DDH) vary between 1.5 and 20/1000 births.[2][3] The prevalence of DDH is clouded by the absence of definitive diagnostic criteria and the wide range of mild to severe anatomic variations that fall within the spectrum. The reported prevalence of DDH has increased significantly since the advent of clinical and sonographic screening, suggesting the possibility of overdiagnosis.[4] The vast majority of cases are identified in the first year of life, and most of these within the first months of life. DDH is more common in girls, with a 4-fold increased risk compared with boys.[4] In the US, the condition is more common among white people than among black people. The condition is also more common in infants who are breech at or near-term delivery.[4][5]
