Project Description

The area between the peritoneum and the posterior abdominal wall constitutes a surgically challenging region of anatomy. A complex network of nerve plexuses occupy this space, including the lumbosacral plexus, the sympathetic trunk, and the inferior mesenteric plexus.

For numerous spinal disorders, the anterolateral retroperitoneal space and its contents will require careful consideration when planning treatments and/or surgical approaches.

The principle aim of this poster is to provide neurosurgical residents with a thorough explanation of the relevant surgical anatomy for two approaches that make use of the anterolateral retroperitoneal space: the oblique lumbar interbody fusion (OLIF), and the lateral lumbar interbody fusion (LLIF). The illustrations will help the novice surgeon better visualize this intricate region of the body.
