What is sacrotuberus ligament?

The sacrotuberous ligament is a thick, fibrous band that runs between the sacrum and the ischial tuberosity (part of the pelvis). It is a strong ligament that helps to support the sacrum and the weight of the upper body.

The sacrotuberous ligament is located deep in the pelvic region and is one of the four major ligaments that attach to the sacrum. These ligaments include the sacrospinous ligament, the sacroiliac joint ligaments, and the iliolumbar ligament. Together, these ligaments form a complex network that stabilizes the sacrum and helps to transfer weight and forces between the upper and lower body.

The sacrotuberous ligament is an important site for muscle attachments, including the gluteus maximus and the hamstring muscles. Injuries to this ligament can occur from trauma, overuse, or repetitive strain and can result in pain and dysfunction in the pelvis and lower back region. Treatment typically involves a combination of rest, gentle stretching, and strengthening exercises. In severe cases, surgery may be necessary to repair or reconstruct the ligament.
