Where this comes from

Abstract

The anterior intrapelvic (AIP) approach has become a standard technique for the fixation of acetabular fractures. While the critical steps for performing the AIP approach are well described in the literature, a comprehensive overview of the anatomical structures at risk remains limited. This review aims to provide an in-depth understanding of the AIP approach with a focus on the historically "nonorthopaedic" surgical anatomy and associated risks. Ultimately, this knowledge empowers orthopaedic trauma surgeons to perform acetabular surgery with improved exposure, safety, and confidence.
