Buttocks

Description

Profile anatomy of the female gluteal region is rendered in a left lateral view, emphasizing the surface contour created by gluteus maximus overlying the posterior ilium and proximal femur. Superiorly, the curve approaches the iliac crest and posterior superior iliac spine region; anteriorly it transitions toward the lateral hip over the greater trochanter where gluteus medius contributes a subtle convexity. Inferiorly, the gluteal fold marks the junction with the posterior thigh, with the proximal hamstring mass lying deep and distal to the ischial tuberosity. Blue briefs preserve modesty while leaving the lateral buttock silhouette readable. Surface landmarks in this projection matter because clinicians rely on them when translating three-dimensional pelvic anatomy to the patient. The superolateral quadrant of the buttock, corresponding to the upper outer portion over the gluteus medius, remains the safest region for intramuscular injection to reduce risk to the sciatic nerve and inferior gluteal vessels, which course deeper and more medial. Orthopedic and sports medicine teaching also benefits from this stance and alignment: the relationship between the greater trochanter and the lateral gluteal contour helps explain abductor dysfunction, Trendelenburg gait, and postoperative changes after total hip arthroplasty or direct lateral approaches. Clean posture. No distraction. Use this figure in gross anatomy and surface anatomy curricula to teach pelvic and hip topography, in nursing skills modules for gluteal IM injection site selection, and in patient-facing materials discussing hip pain referral patterns, trochanteric bursitis, or gluteal tendinopathy. It also fits editorial contexts addressing diversity in anatomical reference imagery and proportional norms in adult female body habitus.
