ADDUCTOR AND PSOAS RELEASE FOR SUBLUXATION OF THE HIP IN CHILDREN WITH SPASTIC CEREBRAL-PALSY

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 fo r 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 n one was dislocated. None of the 27 hips that were normal preoperativel y either subluxed or dislocated during the study period. Nineteen of t he subluxed hips became normal, and five remained subluxed. Adductor a nd psoas releases prevent hip subluxation and provide a measure of pro tection to the opposite hip.
