Iliakarterna

Iliakarterna, also known as iliac crests, are the prominent ridges of bone that run along the upper part of the iliac bones in the human pelvis. These structures are located on the lateral aspects of the pelvis and are easily palpable, forming the upper boundary of the iliac fossa. The iliac crests are significant landmarks in anatomy and are often used as reference points for various medical procedures and examinations.

The iliac crests are composed of dense, cancellous bone and are covered by a layer of fascia. They are connected to the sacrum by the sacroiliac joints and to the pubic bones by the pubic symphysis. The iliac crests are important for muscle attachment, with several muscles, including the iliacus and the tensor fasciae latae, originating from or inserting onto these structures.

In clinical settings, the iliac crests are often used as landmarks for needle aspiration of the joint, which can help diagnose conditions such as septic arthritis. They are also used as reference points for various imaging techniques, such as ultrasound and computed tomography (CT) scans, to assess the pelvis and surrounding structures.

The iliac crests are typically symmetrical, but asymmetry can occur due to various factors, including trauma, tumors, or congenital abnormalities. Asymmetry may be detected through physical examination or imaging studies and can be an important clue to underlying pathology.

In summary, the iliac crests are prominent bony landmarks in the pelvis that play a crucial role in muscle attachment and serve as reference points for various medical procedures and examinations. Their anatomy and clinical significance make them an essential topic in the study of human anatomy and medicine.
