Repair of the sacrotuberous ligament was not traditionally performed as part of the transgluteal approach, but we believe that repair is important for stability of the sacroiliac joint.
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.
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 sides are created by the right and left pubic arch and the sacrotuberous ligaments (Figure 2).
The iliolumbar ligament is one of three vertebral-pelvic ligaments responsible for stabilizing the lumbrosacral spine in the pelvis, along with the sacrospinous and sacrotuberous ligaments. Along with these three are the sacroiliac (SI) ligaments, which also help to stabilize the spine.
The long and short posterior sacroiliac ligaments, the interosseous ligaments within the sacroiliac joints and the sacrotuberous ligaments all resist forces leading to vertical translation between the ilia and the sacrum.
