Male Hip Joint Shown, Posterior View

Description

Posterior surface anatomy of the adult male hip (regio coxae) is presented with the pelvis as the fixed reference, centered on the gluteal fold (sulcus glutealis) where the inferior border of gluteus maximus meets the proximal posterior thigh. Superior to the fold, the convexity of the buttock overlies gluteus maximus, while the lateral contour tracks toward the greater trochanter of the femur, a palpable landmark just inferior to the iliac crest. Medially, the intergluteal cleft marks the midline over the sacrum and coccyx; inferiorly, the transition into the posterior femoral region is clear. Surface landmarks in this posterior perspective matter because they guide palpation and safe procedural planning around the hip joint and gluteal region. Clinicians use the relationship of the greater trochanter to the buttock contour and gluteal fold to estimate femoral head and acetabular orientation, and to differentiate hip pathology from lumbar or sacroiliac referral patterns during examination. A practical correlation: intramuscular injection technique relies on reliable posterior and lateral gluteal landmarks to avoid the sciatic nerve, which courses deep to gluteus maximus and emerges inferior to piriformis. Common use cases include teaching regional anatomy in gross anatomy lab and physical examination courses, illustrating hip and pelvic surface anatomy in musculoskeletal textbooks, and supporting patient-facing diagrams for hip pain localization and postoperative care instructions after posterior-approach total hip arthroplasty. It also fits clinical training materials for palpation, landmarking, and safe gluteal injection site selection. Anatomical accuracy verified by SciePro's Medical Advisory Board.
