Abstract

Fifty-one skeletally immature cerebral palsied (C.P.) children with 70 subluxated or dislocated hips were treated by conservative methods: femoral osteotomy (65 hips), pelvic osteotomy (52 hips) and arthrotomy when necessary (19 cases). 31 children were less than 10 years of age when operated on (mean 6 years, 6 months), 20 children were more than 10 years of age (mean 13 years, 13 months); mean follow-up was 4 years. Reduction and coverage were achieved and maintained in all patients, except for 6 redislocations: a pelvic obliquity was neglected in 3 cases; femoral shortening was not performed in 2 cases. Post-operative course was difficult in eldest patients with pain and stiffness but functional result was acceptable at follow-up in all cases except redislocations. Open reduction was related to a higher rate of postoperative rehabilitation problems. Modeling of previously deformed femoral heads and improvement of hip mobility were consistently seen at last follow-up, except for 3 redislocations. It is concluded that conservative methods are quite advisable in CP children and adolescents. Hip reduction should be preferred to femoral resection even in adolescent.
