Definition
There are two sections of the abdominal wall
The anterior abdominal wall forms the anterior limit of the abdominal viscera and is defined superiorly by the xiphoid process of the sternum and costal cartilages and inferiorly by the iliac crest and pubic bones of the pelvis.
The posterior abdominal wall is a musculoskeletal structure with numerous vascular and lymphatic structures formed by the lumbar vertebrae and their intervertebral discs, pelvic girdle, posterior abdominal wall muscles and their fascia. It supports the retroperitoneal viscera and neurovascular structures.
It should be noted that the posterior abdominal wall does not have a consensus definition and the psoas and quadratus lumborum muscles are sometimes included as the posterior compartment of the retroperitoneum
