Spasticity in the muscles around the hip places abnormal forces on the joint. Over time, especially in children with more involved cerebral palsy, the hip may be forced out of the socket. As the child ages, the dislocated hip can become very painful. Hip dislocation can hinder walking and personal care as well.
Children with cerebral palsy should be periodically screened for hip dislocation. Orthopaedic surgeons at The Children's Hospital of Philadelphia include a careful examination of hip motion and an X-ray, if appropriate, in your child's initial orthopaedic evaluation. If there are signs of dislocation, follow-up screenings will be done once or twice a year to monitor the condition.
If the hip muscles (hip adductors) show signs of dislocation, they may need to be released to stop progression of the condition. Hip adduction with a scissoring gait is a common deformity.
If the condition deteriorates, hip reconstruction may be necessary. Surgery may be performed on both the muscle and bone to relocate the hip in the socket and help keep it there. Surgery to correct this is called pelvic osteotomy and femoral varus-derotation osteotomy.
