Role of intraoperative arthrogram in decision making of closed versus medial open reduction of developmental hip dysplasia (original) (raw)

Background: Hip arthrography in developmental dysplasia of the hip (DDH) has the advantages of viewing the shape and size of the cartilaginous part of both the femoral head and acetabulum, besides the soft tissue obstacles. The aim of the work was to assess the role of arthrogram in evaluation of closed reduction of developmental dysplasia of the hip.Methods: This prospective study included 30 patients with 36 involved hips who presented with DDH. This study included 7 males (23.3%) and 23 females (76.7%). There were 6 patients with bilateral hip involvement (20.0%) and 24 patients with unilateral involvement (80.0%). In this study we used 3 ml Urografin 76% diluted in 7 ml saline and 3 to 5 ml of diluted Urografin was injected into the hip joint.Results: Out of the 36 hips, closed reduction was successful in 33 hips (91.7%) and failed in 3 (8.3%). After the interpretation of the arthrogram we considered the reduction of 7 (21.2%) reduced hips nonconcentric because of the soft tissu...
