[Value of pelvic osteotomy in the management of the hip in children with cerebral palsy].
OBJECTIVE
The authors analyzed the effectiveness of pelvic osteotomy for the treatment of hip dislocation or subluxation in CP children.


METHODS
Fifteen pelvic osteotomies were performed on 11 children aged 30 months to 12 years (mean age 6 years). Seven children suffered from Little's disease. Follow-up averaged 10 years (from 2 to 16). Six children were reviewed at the end of growth (9 cases).


METHODS
A Salter or triple osteotomy with adductor release was performed. Four cases had also a proximal femoral osteotomy.


RESULTS
Following surgery, the mean Reimers' percentage decreased from 55 to 0 per cent. Correction was perfect in 11 cases, incomplete in 4 but excentration remained under 20 per cent. At the end of growth, 6 out of 9 hips remained stable without any further surgery, 2 hips developed slight excentration (less than 20 per cent) and one recurrent subluxation was treated by proximal femoral osteotomy. Six hips remained stable but their growth was not ended at last review.


CONCLUSIONS
This surgical procedure is compared to others described in literature. Pelvic osteotomy with tenotomy improves acetabular cover and corrects muscle imbalance. Its risks seem overestimated in the literature. Both pelvic and femoral osteotomies are useful in specific cases.


CONCLUSIONS
Triple or Salter osteotomy with adducter release seems to be a useful procedure to restore good hip morphology at the end of growth. No posterior dislocations following this osteotomy were seen in spite of the important correction. Proximal femoral osteotomy is not always necessary.
