LIGAMENTUM SACROILIACUM POSTERIUS Meaning and
Definition
-
The term "ligamentum sacroiliacum posterius" refers to a specific ligament that is situated in the region of the sacroiliac joint in the human body. In terms of anatomical location, the sacroiliac joint is formed between the sacrum bone, located just below the lumbar vertebrae, and the ilium bone, which forms part of the pelvic girdle. The joint is responsible for transmitting forces between the lower back and the lower limbs.
The ligamentum sacroiliacum posterius, also known as the posterior sacroiliac ligament, is one of the ligaments associated with the sacroiliac joint. It is located at the posterior aspect of the joint, attaching the sacrum to the ilium. This ligament plays a vital role in maintaining stability and supporting the joint, preventing excessive movement and ensuring proper alignment.
The ligamentum sacroiliacum posterius consists of strong fibrous tissue that connects the bones of the sacrum and the ilium. It helps to reinforce the joint by limiting excessive movements, such as rotation and torsion. This ligament is thicker and more robust than other sacroiliac ligaments, providing additional support to the joint.
In summary, the ligamentum sacroiliacum posterius is a strong fibrous ligament located in the posterior aspect of the sacroiliac joint. It plays a key role in providing stability, limiting excessive movements, and supporting the joint.
