Superior Gluteal Nerve, Lateral View

Description

Arising from the posterior divisions of the L4 to S1 ventral rami, the superior gluteal nerve emerges from the sacral plexus on the posterolateral pelvic wall and exits the pelvis through the greater sciatic foramen. In lateral perspective it courses superior to the piriformis, then runs laterally between gluteus medius and gluteus minimus as it approaches the deep surface of tensor fasciae latae. The sciatic nerve sits inferior and posterior in the greater sciatic notch region, while the iliac crest lies superior to the nerve’s terminal branching over the lateral ilium. Damage to this nerve is a classic complication of misplaced intramuscular injections or operative exposure of the upper buttock, and it is one of the injuries you worry about during a lateral or anterolateral approach to the hip. Denervation of gluteus medius and minimus produces abductor weakness with a Trendelenburg gait, and chronic injury can show as fatty atrophy on MRI in the lateral hip compartment. Small nerve, big consequence. Licensing teams and authors often need this exact lateral relationship to teach safe gluteal injection technique (superolateral quadrant), to annotate hip arthroplasty and pelvic fracture content, or to illustrate sacral plexus anatomy alongside the greater sciatic foramen in gross anatomy and physical therapy coursework. It also fits well in neurology and sports medicine materials discussing hip abductor insufficiency and pelvic nerve entrapment. Anatomical accuracy verified by SciePro's Medical Advisory Board.
