Anatomy

The Greater Sciatic Foramen is formed by the pelvic bone, more specifically, the ischium and the sacrum. It is bounded by the greater sciatic notch, the sacrotuberous ligament, and the sacrospinous ligament.

• Sciatic nerve
• Inferior gluteal artery
• Superior gluteal artery
• Pudendal nerve
• Internal pudendal artery
• Nerve to quadratus femoris
• Nerve to obturator internus

Clinical Significance

Due to its role as a passageway for several important nerves and vessels, any obstruction or injury to the Greater Sciatic Foramen can lead to significant clinical implications, such as sciatica or piriformis syndrome.
