ONE-STAGE TREATMENT OF CONGENITAL DISLOCATION OF THE HIP IN OLDER CHILDREN

We reviewed the results of a primary one-stage combined operation in 4 7 patients (55 hips) who were greater than or equal to 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 re sults, and 65% were good or excellent radiologically. Avascular necros is occurred in four patients, and redislocation also occurred in four patients. We concluded that most of the children who are greater than or equal to 4 years and who have congenital dislocation of the hip can successfully be treated with an extensive one-stage operation consist ing of open reduction combined with innominate osteotomy and femoral v arus, derotation, and shortening osteotomy.
