What is sacrotuberous lig?

The sacrotuberous ligament is a strong fibrous band that runs from the back of the sacrum (the triangular bone at the base of the spine) to the ischial tuberosity (the bony protrusion at the base of the pelvis). It forms part of the pelvic floor, which supports the organs in the lower abdominal region, and provides stability to the pelvis.

The sacrotuberous ligament is triangular in shape, and has two main parts: the superior and inferior parts. The superior part is wider and thicker, and attaches to the lower border of the sacrum, while the inferior part is thinner and attaches to the upper part of the ischial tuberosity.

This ligament is an important structure that is involved in stabilizing the pelvis during movements such as walking, running, and jumping. It also helps to prevent excessive rotation of the pelvis, which can lead to back pain and other musculoskeletal problems.

Injuries to the sacrotuberous ligament are relatively rare, but can occur as a result of excessive stretching or tearing of the ligament during physical activity. Symptoms of sacrotuberous ligament injury include pain in the lower back, buttocks, or posterior thigh, as well as difficulty walking or sitting. Treatment typically involves rest, icing, and physical therapy to help strengthen the surrounding muscles and promote healing. In severe cases, surgery may be necessary to repair the ligament.
