About

Is the anatomical reduction of osteochondral impaction in the acetabular fractures will improve the functional outcome? Despite the increasing amount of literature related to the management of anteromedial dome impactions and marginal impactions, there are still remaining issues and controversies pertaining mainly to the exact anatomy and location of the lesion, the best method of reduction, the need and type of subchondral void filling, the best method of stabilization, the need of reduction in elderly population and its true value as an outcome prognostic factor.

Full description

The reduction of the impacted fragment done through many ways and techniques , all acetabular approaches can be used to reach to the impacted part or through independent cortical window, The impacted part can be reached through the fracture itself as in marginal impaction through the posterior wall and in anteromedial impaction through the quadrilateral plate. Then using a bone graft as a void filling which can be taken from iliac bone or greater trochanter. Post-operative x-rays and computed tomography scan will be done to all patients , Radiological grading immediate post-operative and at the last follow-up according to Matta , Heterotopic ossification will be classified according to the Brooker classes on an Anteroposterior radiograph, Posttraumatic arthritis will be evaluated according to the method by Kellgren and Lawrence, functional outcome will be assessed according to Merle D'Aubigne and Postel scoring which was modified by Matta, Avascular necrosis of hips will be classified according to Ficat and Arlet classification.
