The lesser sciatic foramen is a small anatomical structure found in the pelvis. It is formed by several bones and ligaments, and it serves as a passageway for several important nerves and vessels.

The superior boundary of the lesser sciatic foramen is formed by the sacrospinous ligament. This ligament runs from the sacrum to the ischial spine, creating the upper edge of the foramen.

The inferior boundary of the lesser sciatic foramen is formed by the sacrotuberous ligament. This ligament runs from the sacrum to the ischial tuberosity, creating the lower edge of the foramen.

The anterior boundary is formed by the ischial spine and part of the ischium, while the posterior boundary is formed by the sacrum and the sacrotuberous ligament.

So, to summarize, the lesser sciatic foramen is bounded superiorly by the sacrospinous ligament, inferiorly by the sacrotuberous ligament, anteriorly by the ischial spine and part of the ischium, and posteriorly by the sacrum and the sacrotuberous ligament.
