An Anterior View Of The Hip Bone Marking The Anterior Superior Iliac Spine

Description

Rotating through an anterior perspective of the os coxae, the animation centers on the anterior superior iliac spine (ASIS) at the anterior end of the iliac crest. The ASIS is shown lateral to the anterior inferior iliac spine and superior to the acetabulum, with the iliac fossa forming the broad internal surface medial to the crest. As the camera tracks and reorients, the crest’s curvature becomes clear as it runs posteriorly from the ASIS while the pubic tubercle and anterior margin of the pelvic brim sit more medially and inferiorly. Palpation and surface anatomy hinge on this landmark. Clinicians use the ASIS to orient pelvic tilt and leg length assessment, and it anchors measurements such as true versus apparent limb length in hip pathology. The sequence also clarifies why the ASIS is a high-yield attachment site: the sartorius originates here and the inguinal ligament spans from the ASIS to the pubic tubercle, a relationship that matters when teaching femoral hernia anatomy and when planning anterior approaches around the groin. Easy to miss in a static plate. Use this animation in gross anatomy labs when introducing the bony pelvis, in sports medicine teaching on iliac apophysitis and ASIS avulsion injuries in adolescent sprinters, or in radiology education to improve landmark identification on AP pelvis radiographs and pelvic CT.
