Iliac spine

Iliac Spine is a significant anatomical landmark located in the human pelvis. It is divided into two parts: the anterior iliac spine and the posterior iliac spine. These structures are essential for muscle attachment and provide a reference point in orthopedic surgery.

Anatomy

The Iliac Spine is part of the ilium, the largest bone of the pelvis. The anterior iliac spine is further divided into the superior and inferior spines. The superior spine provides attachment for the inguinal ligament and the sartorius muscle, while the inferior spine is a point of attachment for the rectus femoris muscle and the iliofemoral ligament.

The posterior iliac spine, like the anterior, is divided into superior and inferior parts. The superior part serves as an attachment point for the posterior sacroiliac ligament and the multifidus muscle. The inferior part is a point of attachment for the sacrotuberous ligament and the coccygeus muscle.

Clinical Significance

The Iliac Spine is a crucial landmark in various surgical procedures, including hip arthroplasty and lumbar puncture. It also plays a role in diagnosing conditions such as appendicitis and hip dysplasia.
