Intra-articular screw placement during acetabular surgery must be avoided. To date, no anatomic guidelines exist to prevent intra-articular screw placement in the treatment of complex acetabular fractures by the ilioinguinal or Stoppa approach. ⋯ This study identifies a safe zone for screw placement in the treatment of acetabular fractures when operated by an anterior approach. These findings have the potential to prevent further injury to the acetabular and femoral cartilage as a result of the surgical trauma and minimize intraoperative irradiation time.

Report the technical aspects, radiographic results, and complications after minimum 1-year follow up of the anterior intra-pelvic (AIP or modified Rives-Stoppa) approach as an alternative to the ilioinguinal approach for the treatment of acetabular fractures. ⋯ Use of the AIP (modified Rives-Stoppa) approach for the treatment of acetabular fractures permits good to excellent reduction in the majority of cases while giving excellent visualization and access to the quadrilateral plate and posterior column. The AIP approach has a complication rate that is comparable to the ilioinguinal approach. We recommend the use of this technique as a potential alternative (but not replacement) to the classic ilioinguinal approach when anterior exposure of the acetabulum is required.
