One-Stage Treatment of Congenital Dislocation of the Hip in Older Children

Abstract

We reviewed the results of a primary one-stage combined operation in 47 patients (55 hips) who were > or = 4 years and had congenital dislocation of the hip. At a mean follow-up of 7.5 years (2-16 years), 67% of the whole series had good or excellent clinical results, and 65% were good or excellent radiologically. Avascular necrosis occurred in four patients, and redislocation also occurred in four patients. We concluded that most of the children who are > or = 4 years and who have congenital dislocation of the hip can successfully be treated with an extensive one-stage operation consisting of open reduction combined with innominate osteotomy and femoral varus, derotation, and shortening osteotomy.
