Ilioinguinal Approach: Indication and Technique

Abstract

This video on the ilioinguinal approach presents its indications and techniques for the operative treatment of acetabular fractures. The principle of the ilioinguinal approach is to work through 3 different windows. The lateral window gives access to the pelvic bone from the sacroiliac joint to the lateral border of the iliopsoas muscle, the middle window accesses the medial border of the iliopsoas muscle to the femoral artery, and the medial window allows for control of the anterior pelvic ring medially from the femoral vein to the symphysis pubis. In this video, we demonstrate anatomical reconstruction of the acetabulum in a patient with an associated both-column fracture using the ilioinguinal approach. Indications are all acetabular fracture types, where in addition to anterior column fracture, a fractured posterior column is reducible through the middle window, that is, there is no involvement of the posterior column or wall that would necessitate a direct posterior approach. The ilioinguinal approach is a standard anatomical approach that gives an excellent visual and palpatory exposure of the anterior column up to the symphysis pubis and of the quadrilateral plate. Indications and techniques, how to develop this approach for the anatomical reduction and fixation of appropriate acetabular fractures, are demonstrated in this video.
