LIGAMENTUM ARCUATUM PUBIS Meaning and
Definition
-
The ligamentum arcuatum pubis, commonly known as the pubic arch ligament, is a structure found in the pelvis that plays a significant role in stabilizing and connecting the pelvic bones. It is a fibrous band composed of dense collagen fibers and is situated just below the pubic symphysis, which is the midline joint connecting two pubic bones in the front of the pelvis.
The ligamentum arcuatum pubis forms an arch-like shape, hence its name, and spans across the anterior surface of the pelvic outlet. It connects and reinforces the lower parts of the two pubic bones and helps to maintain their position and stability. The ligament is positioned underneath the pelvic floor muscles and is located within close proximity to the bladder, urethra, and other pelvic organs.
Functionally, the ligamentum arcuatum pubis assists in supporting the pelvic floor structures and aids in maintaining continence. It contributes to the overall stability of the pelvic girdle and assists in transmitting forces between the legs and the pelvis during weight-bearing activities such as walking, running, and jumping. Additionally, the ligamentum arcuatum pubis has been observed to provide additional structural support to the pubic symphysis, particularly during pregnancy and childbirth.
In summary, the ligamentum arcuatum pubis is a fibrous band situated below the pubic symphysis that helps stabilize the pelvis, supports the pelvic organs, and helps transmit forces during weight-bearing activities.
