DDH
Also written as: DDH — developmental dysplasia of the hip
Developmental dysplasia of the hip, a condition where the hip joint forms abnormally in infants and children.
Full Definition
Developmental dysplasia of the hip (DDH) encompasses a spectrum of hip abnormalities ranging from mild acetabular dysplasia to complete hip dislocation. Previously known as congenital hip dysplasia, the term was changed to reflect that the condition can develop after birth. DDH is one of the most common orthopedic conditions in newborns, with higher prevalence in females and breech presentations. Early detection and treatment are crucial for optimal outcomes.
Usage
Usage note: Preferred over the outdated term 'congenital hip dysplasia (CDH)'. Always spell out on first use in patient documents.
