One-stage correction of the dysplastic hip in cerebral palsy with the San Diego acetabuloplasty: results and complications in 104 hips.

McNerney NP1, Mubarak SJ, Wenger DR.

Abstract

Ninety-two patients with cerebral palsy underwent a special type of pericapsular acetabuloplasty designed to correct the hip dysplasia that occurs in cerebral palsy. The osteotomy was performed as part of a combined procedure (including femoral osteotomy and soft-tissue releases). Retrospective analysis was performed on 75 of the children (104 hips from 1982 through 1995) with a mean follow-up of 6.9 years. Ninety-nine (95%) of the 104 hips remained well reduced at follow-up. There were no redislocations. If the preoperative migration percentage was >70% (severe subluxation), improved results were noted in hips that had an open reduction with capsulorrhaphy. There were 13 complications including intraarticular extension of the acetabuloplasty (one) and avascular necrosis of the femoral head (eight hips, 8%). Indications for addition of a pericapsular acetabuloplasty include an open triradiate cartilage, acetabular dysplasia (acetabular index >25 degrees), and subluxation or dislocation with a migration percentage of >40%. Even hips with relative incongruity and some deformity of the femoral head can be successfully treated with this combined approach
