Adductor and psoas release for subluxation of the hip in children with spastic cerebral palsy.

Abstract

Forty-four hips in 22 children between the ages of 2.0 and 6.0 years (mean, 4.0 years) with cerebral palsy were followed-up prospectively for a minimum of 5 years. Of the 44 hips studied preoperatively, 20 were radiologically normal, 24 were subluxed, and one was dislocated. Five years postoperatively, 39 hips were normal, five were subluxed, and none was dislocated. None of the 27 hips that were normal preoperatively either subluxed or dislocated during the study period. Nineteen of the subluxed hips became normal, and five remained subluxed. Adductor and psoas releases prevent hip subluxation and provide a measure of protection to the opposite hip.
