developmental dysplasia of the hip
Also written as: DDH — developmental dysplasia of the hip
A condition where the hip joint forms abnormally, ranging from mild socket shallowness to complete hip dislocation.
Full Definition
Developmental dysplasia of the hip (DDH) encompasses a spectrum of abnormalities in hip joint development, ranging from mild acetabular dysplasia to complete hip dislocation. The condition was formerly known as congenital hip dysplasia, but the current term reflects that abnormalities may develop or worsen after birth. Risk factors include female sex, breech presentation, family history, and certain cultural practices involving tight swaddling. Early detection through physical examination (Ortolani and Barlow maneuvers) and ultrasound screening is crucial for optimal outcomes. Treatment varies by age at diagnosis and severity, ranging from observation and positioning in mild cases to Pavlik harness application in infants or surgical intervention in older children. Untreated DDH can lead to early arthritis and significant disability.
Usage
Usage note: Preferred term over 'congenital hip dysplasia.' Note that Pavlik harness is the preferred initial treatment in infants.
