What leaves the pelvis through the lesser sciatic foramen?

i didnt know there was a lesser sciatic foreman, i thought there was just a lesser sciatic notch.

There is however an obturator foreman which is closed by collagen fibers which provide a firm base for the attachment of muscles to the hip.

Normally, I would not answer a question like this as my expertise is generally in medication but I had severe sciatica while I was pregnant with my 3rd child (after having had twins) and I had sciatica so bad that I was finding it difficult to walk. I tried massage therapy and physical therapy and could not take medication

I went to the chiropractor and the pain was instantly relieved. My hips and lower back were out of alignment because I had carried twins the year before. On occasion a Doctor of Osteopathy (DO) can also work but they usually only work on one joint at a time - the chiropractor will do your whole back which works faster. Anyone who does not believe in chiropractors will tell you they are quacks - don't listen.

I don't necessarily believe that chiropractors can cure things like diabetes but they can definitely relieve some types of back pain especially if a pinched nerve is involved which is usually the cause of sciatica.
