Surgical correction of acetabular dysplasia in the adult. A Boston experience.

Abstract

Acetabular redirection surgery is the mainstay of treatment for the symptomatic, dysplastic hip. The authors' experience with the Salter innominate osteotomy, Wagner spherical acetabular osteotomy and the modified Bernese periacetabular osteotomy shows that major acetabular redirection surgery can reliably improve the structure of the dysplastic hip and delay or prevent secondary osteoarthrosis. The limited correction achieved by the Salter innominate osteotomy suggests this procedure generally should be reserved for younger patients with mild dysplasia. The modified Bernese periacetabular osteotomy is the authors' current preferred method of treating acetabular dysplasia, even in the presence of mild to moderate secondary osteoarthrosis.
