Late Reduction in Congenital Dislocation of the Hip and the Need for Secondary Surgery

Despite early recognition and appropriate treatment of congenital dislocation of the hip, there are a number of cases that subsequently require further surgery to prevent progressive dysplasia, instability, and eventual early osteoarthritis. This study aimed (1) to determine the incidence of pelvic osteotomy (PO) after late open (OR) or closed (CR) reduction for failed initial conservative treatment or late presentation; (2) study potential radiologic predictors of those that will require a secondary procedure; (3) and to evaluate the effect of potential confounding variables including age of reduction, Pavlik harness treatment, and surgical experience on PO rate.
