The Pudendal nerve is the structure that passes through the lesser sciatic foramen.
greater ischiadic (sciatic) notch

A groove in the pelvis
Greater Sciatic Notch
the two branches of the sciatic nerve
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.

The greater sciatic notch.
coxal bone
greater sciatic notch
greater sciatic notch
A groove in the pelvis
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
The nerve (the sciatic) goes to the muscles that move the leg. If the "pinching" is removed by opening the foramen (Foraminal Stenosis) that the nerve goes through, the ability to walk will come back.
