Ilioinguinal Approach AO Foundation

Description: The ilioinguinal approach was developed by Emile Letournel based on cadaveric dissections to provide anterior access for fractures of the acetabulum. It provides exposure of the inner aspect of the innominate bone from the sacroiliac joint to the pubic symphysis. The surgical exposure requires development of three wound intervals. Mobilization of the femoral vessels and nerve, as well as the spermatic cord (male) or round ligament (female), is key to the development of these intervals. Articular reductions, using the ilioinguinal approach, are done indirectly. They are based on meticulous restoration of extraarticular anatomy, since the joint can not be directly visualized with this approach.
