Cerebral palsy (CP) encompasses a group of disorders pertaining to abnormalities in movement, tone, and/or posture due to a nonprogressive lesion to an immature brain. Hip dysplasia is the second most common orthopedic deformity seen in CP, and its severity can range from a hip at risk for subluxation to full hip dislocation with degenerative changes. The purpose of this article is to review the hip pathologies that occur in CP focusing on their pathogenesis, physical exam findings, impact on function, and conservative treatment. Through a review of the medical literature, it is demonstrated that early, aggressive, and comprehensive care led by a pediatric physiatrist is essential to mitigate progression to complete hip dislocation and preserve range of motion, prevent contracture, and promote maximum functional ability in all children with CP.
