The sciatic nerve originates from the L4- S2 nerve roots and goes to the front of the sacrum, passing under the piriformis muscle. Different anatomical variations of the sciatic nerve have an effect on piriformis syndrome. The peroneal and tibial are the two divisions of the sciatic nerve. These two divisions are commonly bound together, but in certain cases they are split when they pass through the piriformis muscle, which can have different effects on the piriformis syndrome.
