Combined hip surgery in cerebral palsy patients

Abstract

Seventeen cases of dislocated/subluxated hips in 14 cerebral palsy patients that were relocated by the combined hip procedure were reviewed. The combined hip procedure includes varus derotation osteotomy, open reduction, innominate bone osteotomy, adductor releases, and iliopsoas recession, all done at one stage. Eleven patients were spastic quadriplegic, 1 was spastic diplegic; and 2 were spastic hemiplegic. Average age at operation was 10 years. Average follow-up was 3 years. A total of 16 hips (94%) remained stable at follow-up with almost no change in center edge angle and the migration percentage, although the neck shaft angle remodeled over time. We conclude that the combined hip procedure is effective in maintaining hip reduction in cerebral palsy patients.
