Perineal anterior dislocation of the hip with avulsion fracture of greater trachnanter in a child

Abstract

Traumatic anterior dislocation of the hip is rare even in children. Very uncommon also is the perineal variant of the inferior type of anterior dislocation with concomitant avulsion fracture of the greater trochanter. We report such a case highlighting the peculiarity of its management. No similar case of triumvirate injury of the hip has been reported in sub Saharan West Africa. Open reduction of the hip under general anaesthesia was done after two failed attempts at close reduction.
One year after, radiograph of the hip showed no deformity of the head of femur nor evidence of avascular necrosis.
