This is the largest foramen leading to and from the pelvis. One of the structures is the sciatic nerve. The foramen might be somewhat "closed" by bone and can "pinch" the sciatic nerve. This is very painful and a person can't dorsiflex the foot. Surgery can open the foramen and reduce the pain and disability.
The sciatic nerves exit the pelvic bone through an opening (greater sciatic foramen) to emerge in the buttock.
If you look up the nervous system there are 3 places in your lower back that cause Sciatic or pinched nerve in three locations. Lower lumbar back at 3,4,5, cause pain in the left or right backside cheek, a shorter nerve. One causes pain that comes into the groin are from the backside around and up through groin. One causes the pain that runs down the outside seem of your pants and can end of in the second little toe. (next to the pinkie toe) It is called the Sciatic nerve.
greater sciatic notch
The condition is caused by the irritation or compression of the proximal sciatic nerve by the piriformis muscle, which connects the sciatic notch with the greater trochanter of the femur
YESbecause its the Removal of a portion of bone posterior to the foramen magnum in order to allow greater space for the nervous system structures within.

The obturator foramen is the largest foramen in the human body.
