Abstract
Flank and lumbar hernias are challenging because of their rarity and anatomic location. Several challenges exist when approaching these specific abdominal wall defects, including location, innervation of the lateral abdominal wall musculature, and their proximity to bony landmarks. These hernias are confined by the costal margin, spine, and pelvic brim, which makes closure of the defect, including mesh placement, difficult. This article discusses the anatomy of lumbar and flank hernias, the various etiologies for these hernias, and the procedural steps for open and robotic preperitoneal approaches. The available clinical evidence regarding outcomes for various repair techniques is also reviewed.
