The surgical anatomy of the lumbar plexus refers to the detailed study of the nerves that form this plexus, which is located in the lower back and primarily innervates the lower limbs and parts of the pelvis. The lumbar plexus is formed by the anterior rami of the first four lumbar nerves (L1-L4), with contributions from T12. Its branches include significant nerves such as the femoral nerve, which innervates the anterior thigh muscles, and the obturator nerve, which supplies the medial thigh. Understanding the surgical anatomy is crucial for various procedures, including hernia repairs and hip surgeries, as it helps surgeons avoid nerve damage and complications. Key landmarks include the psoas major muscle, which serves as a guide for identifying the plexus and its branches. Proper knowledge of variations in the lumbar plexus's anatomy can ultimately enhance surgical outcomes and improve patient safety. Delving into the nuances of this anatomical structure provides insights essential for effective surgical planning and execution.
