The Anatomical Structure And Location Of Anterior Superior Iliac Spine Of The Hip Bone

Description

Rotating around the anterior pelvis, the animation isolates the anterior superior iliac spine (ASIS) as a blunt, palpable projection at the anterior end of the iliac crest on the ilium. The ASIS sits superior to the anterior inferior iliac spine and lateral to the pubic tubercle, forming a key anterolateral landmark along the pelvic brim. As the ilium comes into profile, the iliac crest is traced posteriorly from the ASIS, and the relationship of the ASIS to the anterior border of the iliac wing becomes clear. Orientation stays in standard anatomical position. Clinically, the ASIS anchors surface anatomy. Palpation of the ASIS guides measurement of leg length discrepancy (ASIS to medial malleolus), helps localize the inguinal ligament spanning from ASIS to pubic tubercle, and defines safe reference points for pelvic and hip examination. The animated rotation adds what static plates often miss: how small changes in pelvic tilt can shift the perceived prominence of the ASIS and alter landmark-based assessments, including the “hip pointer” contusion common in contact sports and apophyseal avulsion injuries in adolescent athletes. Use this sequence in musculoskeletal anatomy labs when teaching the hip bone, pelvis, and iliac crest, or in clinical skills courses focused on pelvic palpation and landmarking for injections and taping. It also fits radiology and orthopaedics teaching modules that correlate bony landmarks with AP pelvis radiographs and CT surface reconstructions.
