Superomedial impaction of the anterior dome of the acetabulum is a known risk factor for poor outcomes after open reduction and internal fixation of acetabular fractures. The authors, using the anterior intrapelvic (modified Stoppa) approach to the acetabulum, describe a novel technique to help reduce and stabilize marginal impaction of the acetabular dome. In the senior author's experience, this technique has been helpful to achieve adequate reduction and stabilization.

If further preclinical, and later clinical, studies demonstrate reproducible efficacy, guided growth of the proximal femur may eventually become a viable option for treatment or prevention of hip deformity in select patients.
