What is sacro tuberous ligament?

The sacro tuberous ligament is a strong, fibrous band of tissue that connects the sacrum to the ischial tuberosity, which is the bony prominence at the base of the pelvis. The ligament is located in the lower part of the pelvis and is one of the major components of the pelvic floor.

The sacro tuberous ligament is an important stabilizing structure, providing support to the sacrum and the pelvis. It helps to maintain the position of the sacrum during movement and prevents excessive rotation, which could lead to a variety of pelvic problems.

The ligament is composed of collagen and elastic fibers and has a rich blood supply and nerve innervation. It is also an attachment site for several muscles including the gluteus maximus, biceps femoris, and piriformis.

Injuries to the sacro tuberous ligament can cause pain and decreased stability in the pelvis, leading to difficulty with walking and other movements. Treatment for sacro tuberous ligament injuries typically involves conservative measures such as rest, ice, and physical therapy. In severe cases, surgery may be required to repair or reconstruct the ligament.
