sa·cro·tu·ber·ous lig·a·ment

[TA]
the ligament that passes from the ischial tuberosity to the ilium, sacrum, and coccyx, transforming the sciatic notch to a large sciatic foramen, which is then further subdivided by the sacrospinous ligament.

In some patients, the pudendal nerve may actually be attached to the anterior surface of the sacrotuberous ligament.
In our practice, we most often find the nerve entrapped between the sacrospinous and sacrotuberous ligaments, which form a sort of "V" in the pelvis.

This theory is based on an observed partial attachment of the long head of the biceps femoris muscle to the sacrotuberous ligament, which bridges the sacroiliac joint.
A review of anatomical texts revealed that many other muscles and ligaments are also associated with the sacrotuberous ligament, implying that the long head of biceps femoris does not necessarily act in isolation.

The stability of the pelvic ring is determined by the integrity of the posterior weightbearing sacroiliac complex, which includes the sacroiliac (posterior and anterior), sacrospinous, and sacrotuberous ligaments.

Due to its proximal attachment on to the sacrotuberous ligament, gluteus maximus is thought to cause tightening of the ligament, giving dynamic joint stability and thereby reducing mobility (Vleeming et al.
