The most important complication following the treatment of congenital dislocation of the hip is avascular necrosis. The potential sequelae that may arise after the onset of avascular necrosis are worse than if the hip remained dislocated. We evaluated 38 hips in which avascular necrosis developed after reduction. The average patient age at the time of reduction was 4.3 years, with a follow up of 6 to 15 years. Twelve hips had closed reduction and 26 had open reduction. Following reduction, 8 hips had Type I, 6 had Type II, 9 had Type III, and 15 had Type IV avascular necrosis. In this article, we evaluate our cases and review current literature on the subject. Close follow up and timely interventions can reduce potential sequelae to a minimum.
