Comparison of the Ilioinguinal Approach and the Anterior Intrapelvic Approaches for Open Reduction and Internal Fixation of the Acetabulum

The ilioinguinal and anterior intrapelvic approaches to the acetabulum often involve different strategies for the treatment of acetabular fractures. The ilioinguinal approach allows access to the entire internal iliac fossa and pelvic brim, including indirect access to the quadrilateral surface. In contrast, the anterior intrapelvic approach allows access to the anterior elements from inside the pelvis with the surgeon standing opposite the fracture pathology. Therefore, the goal of this article is to clarify the advantages and disadvantages for each approach with respect to exposure, reduction, and fixation.
