Gluteal Region of the Lower Limb

Description

Posterior surface anatomy of the gluteal region is presented on a standing black adult female, with emphasis over the lower lumbar area, pelvis, and buttock (nates). Superficially, the iliac crests and posterior superior iliac spines sit superior and lateral to the sacrum, while the bulk of the buttock corresponds to gluteus maximus draping inferolaterally toward the gluteal fold and proximal thigh. Lateral contour over the hip marks the region of the greater trochanter deep to gluteus medius and minimus, with the proximal iliotibial tract tracking inferiorly along the lateral thigh. Clear landmarks. Surface relationships in this view matter because so many clinical actions rely on them rather than direct visualization. Intramuscular injection site selection uses the superolateral buttock (or ventrogluteal region over gluteus medius) to avoid the sciatic nerve, which courses deep in the posterior hip region toward the posterior thigh. Lateral hip pain from greater trochanteric pain syndrome (gluteus medius/minimus tendinopathy with trochanteric bursitis) and gait deviation from superior gluteal nerve injury (Trendelenburg sign) both map cleanly onto the lateral gluteal contour shown here, making this a practical teaching angle for neurovascular risk and abductor mechanics. Use this asset in gross anatomy and surface anatomy teaching for the pelvis and proximal lower limb, in nursing and emergency medicine materials on safe gluteal injections, and in orthopaedic or sports medicine publishing to orient readers to gluteal tendinopathy and trochanteric pain examination points in patients with darker skin tones.
