ASIS (anterior superior iliac spine)

The anterior superior iliac spine (ASIS) is a bony bump located at the front of the pelvis, at the top front edge of the hip bone. It serves as an important anatomical landmark for healthcare professionals, helping to identify the pelvis's position. The ASIS also plays a role in muscle attachment, supporting muscles involved in hip movement and stability. Its location is useful for various medical procedures, such as hip surgeries, injections, and assessing posture or gait. In everyday terms, it’s a noticeable point on your hips that helps define the front part of your pelvis.
