Frequently reported risk factors for DDH are a positive family history of DDH, female sex and breech presentation, but there is not a lot of systematic knowledge about DDH risk factors. DDH occurs more often in children who present in the breech position.9 It is believed that in utero knee extension of the infant in the breech position results in sustained hamstring forces around the hip and contributes to subsequent hip instability.

Developmental dysplasia of the hip (DDH) is a condition where there is a structural abnormality in the hips caused by abnormal development of the fetal bones during pregnancy.This leads to instability in the hips and a tendency or potential for subluxation or dislocation.These structural abnormalities have the potential to persist into adulthood leading to weakness, recurrent subluxation or . Early detection and subsequent treatment of developmental dysplasia of the hip (DDH) is thought to improve its prognosis.
