Iliac Crest

Iliac crest: anatomical description and functions

The iliac crest is a protrusion on the upper border of the ilium, located between the anterior and posterior iliac spines. It is a wide and flat bone that plays an important role in maintaining the stability of the pelvis and lower spine.

The anatomical structure of the iliac crest consists of three parts: external, middle and internal. The outer part of the iliac crest has a convex shape and serves as an attachment point for the muscles of the gluteal region. The middle part of the iliac crest is the roughest and widest part and serves as an attachment for the abdominal and thigh muscles. The inner part of the iliac crest is concave and serves as an attachment point for the muscles of the lumbar spine.

The iliac crest performs several functions in the human body. It serves as an attachment point for many muscles that play an important role in maintaining the stability of the pelvis and lower spine. In addition, the iliac crest is involved in the movement of the hip by providing an attachment point for the muscles that are responsible for up, down, lateral and rotational movement of the hip.

Also, the iliac crest is an important indicator in determining the level of acute abdominal syndrome. Doctors use this sign to determine the exact location of abdominal pain, which helps facilitate diagnosis and treatment of diseases.

In conclusion, the iliac crest is an important anatomical structure that plays an important role in maintaining the stability of the pelvis and lower spine, and is also involved in hip movement. Knowledge of the anatomical structure and function of the iliac crest can be helpful to physicians and physical therapy and exercise professionals.
