Superior Gluteal Nerve Anatomy and Its Injuries: Aiming for a More Secure Surgical Approach of the Pelvic Region

Because most of the recognized causes superior gluteal nerve (SGN) injury are iatrogenic, detailed knowledge anatomy SGN is crucial to prevent its associated with surgical procedures. This study aims describe precise location or branches at greater sciatic foramen, measure distances these neural structures palpable bony landmarks, and evaluate possible correlation between parameters pelvis size. Twenty human cadaveric hemipelvises were studied. After dissection expose from trochanter (GT), anterior iliac spine (ASIS), posterior (PSIS), ischial tuberosity (IT), notch apex measured. We found that emerges as a common trunk in 75% hemipelvises, already divided inferior 25% hemipelvises. When exits trunk, it does so, cases, contact bone level apex. The median distance PSIS, ASIS, GT IT 7.6 cm, 10.9 7.5 cm 10.8 respectively. positive some analyzed size pelvis. anatomical data this may serve pivotal guides during orthopedic pelvic surgery, contributing minimize SNG iatrogenic lesions significant implications patient’s quality life.
