Medial adductor open reduction for congenital dislocation of the hip.

Abstract

Twenty-two consecutive patients with 26 dislocated hips were evaluated for a mean of 7 years after open reduction through a medial adductor approach. Severin classification of grade I or II and center-edge angles greater than 20 degrees were present in 73% of hips and 88% of patients treated between the ages of 5 and 14 months. Avascular necrosis (AVN) with partial head involvement occurred in 15% of hips and correlated positively with increased age at surgery, but did not preclude a satisfactory Severin classification. Best results were obtained in children treated between the ages of 5 and 14 months.
