Iliac bone 2

Iliac bone: Definition and anatomy

THEhipbone is a wide, flat bone located in the lower part of the back. It is one of the two bones that make up the pelvic girdle. In this article, we are going to discuss the definition, function and anatomy of thehipbone !

Iliac bone: Definition


THEhipbone is the large bone that forms each side of the pelvis. It is connected to the hip bone, sacrum and coccyx to form the pelvic girdle. This belt is very stable and allows great freedom of movement.


THEhipbone is connected to the femur via the coxo-femoral joint. He articulates with the ribs at the lumbar levels. The ilium shaped like a large wing that makes up most of the hip bone.

The iliac bones are connected to the muscles of the pelvic area. These muscles allow a large number of movements in the region of the hip bones.



Iliac Bone Anatomy


THEhipbone is a wide, flat bone that forms an important part of the pelvis. It is located in the lower part of the abdomen and extends from the hip to the lumbar spine. THE'hipbone is connected to the sacrum at the base of the spine and to the femur, or thigh bone, at the hip joint.


This bone has two surfaces: the inner surface, which is concave, and the outer surface, which is convex. The inner surface of thehipbone is smooth and is part of the pelvic cavity. The outer surface of thehipbone is rougher and provides attachment sites for muscles and ligaments.


THEhipbone also has three processes: the ilium, ischium and pubis. The ilium is the flared upper part of thehipbone ; it constitutes the highest point of the basin. The ischium is the lower and central part of thehipbone ; it is part of the hip joint.


The pubis is the lower, forward-pointing part of thehipbone ; it articulates with the pubic bones of other vertebrates to form the pubic symphysis. Together, these three processes provide solid support for the body weight and allow for a wide range of motion at the hip joint.



Iliac bone function


THEhipbone is one of the two large bones that make up the pelvis. Although the pelvis itself is not a load-bearing bone, the iliac bones support the upper part of the body and bear most of its weight.


In addition to providing structural support, the iliac bones also protect organs in the lower abdomen, including the kidneys and colon.


The iliac bones are connected to the lower spine by a system of muscles and ligaments, and they also provide attachments for the hip and thigh muscles. Therefore, they play a vital role in supporting the upper body and allowing movement of the hip joint.

Pathologies involving the iliac bone


THEhipbone is susceptible to a number of pathologies, including:


  • Fractures: Fractures of thehipbone are relatively rare, accounting for only 2-3% of all long bone fractures. They most often occur as a result of high-energy trauma, such as a car accident or a fall from a great height.

  • Sacroiliac injury: Sacroiliac involvement refers to any pathological condition that affects the joints between the iliac bones and the sacrum. It can be degenerative joint disease, inflammatory arthritis, or post-traumatic arthritis.


  • Acetabular dysplasia: acetabular dysplasia, a condition in which the hip socket is shallow. This can lead to iliac crest pain, as well as an increased risk of dislocation.


  • Cancer: Cancer can affect any bone in the body, including the iliac bone. Symptoms of bone cancer can include pain, swelling, and fatigue.



Treatment for these conditions often includes pain medication, physical therapy, and surgery.
