The iliopsoas compartment is an extra-retroperitoneal space that runs along the posterior aspect of the abdomen and pelvis and extends into the thigh.
It should be noted that the posterior abdominal wall does not have a consensus definition and that psoas muscles are sometimes included as the posterior compartment of the retroperitoneum 5.
Gross anatomy
Boundaries
