LIGAMENTA SACROILIACA INTEROSSEA Meaning and
Definition
-
Ligamenta sacroiliaca interossea refers to a group of strong fibrous ligaments that connect and stabilize the sacrum (a triangular bone at the base of the spine) and the ilium (a large, fan-shaped bone forming the upper part of the pelvis) in the human body. These ligaments are located on either side of the sacrum and sacroiliac joint, playing a crucial role in providing support and strength to this joint.
The ligamenta sacroiliaca interossea consists of two major ligaments: the anterior sacroiliac ligament and the posterior sacroiliac ligament. The anterior ligament runs from the anterior surface of the sacrum to the iliac fossa, while the posterior ligament extends from the posterior surface of the sacrum to the iliac tuberosity. Together, these ligaments form a robust network that helps to stabilize and limit the movement of the sacroiliac joint.
The ligamenta sacroiliaca interossea also connect the sacrum to the third and fourth sacral vertebrae, reinforcing the structure of the sacrum. Additionally, they provide protection to the delicate structures, such as nerves and blood vessels, that pass through or around the sacroiliac joint.
Their strength and resistance to excessive movement make the ligamenta sacroiliaca interossea essential in maintaining stability and preventing excessive motion between the sacrum and the ilium. Dysfunction or injury to these ligaments can lead to various conditions, such as sacroiliac joint dysfunction or instability, causing pain and impairing mobility in the pelvis and lower back.
