Hip dysplasia in children with cerebral palsy

Abstract

Neuromuscular hip dysplasia is common in children with cerebral palsy, especially those with GMFCS IV or V functional level. The pathophysiology of progressive hip subluxation and dislocation comes from abnormal muscle tone superimposed over growth and developmental delay. Proactive surgical care in the form of soft tissue releases and hip osteotomy is successful in stopping progressive subluxation and dislocation. Neglected hip dysplasia in CP leads to painful dislocations that can be treated with salvage surgical procedures but with lower success rates than preventive and reconstructive techniques.
