Piriformis syndrome occurs when the piriformis irritates the sciatic nerve, which comes into the gluteal region beneath the muscle, causing pain in the buttocks and referred pain along the sciatic nerve. [8] This referred pain is known as sciatica. Seventeen percent of the population has their sciatic nerve coursing through the piriformis muscle.
Piriformis muscle hypertrophy may cause crowding around the greater sciatic foramen. [22] [23] Both the piriformis and sciatic nerve pass through the greater sciatic foramen and the deep gluteal space. An enlarged (hypertrophic) piriformis muscle may place pressure on nearby structures.
The piriformis is a muscle that runs down from the lower spine to the butt and to the top of the thighs. The muscle extends to each side of your body and is used in almost every movement of the ...

The lateral rotator group is a group of six small muscles of the hip which all externally (laterally) rotate the femur in the hip joint.It consists of the following muscles: piriformis, gemellus superior, obturator internus, gemellus inferior, quadratus femoris and the obturator externus.
According to Harvard Health, piriformis syndrome "develops due to irritation or compression of the sciatic nerve near the piriformis muscle." The condition is more common in women. The condition ...
The inferior gluteal nerve reliably emerged inferior to the piriformis muscle. The branching characteristics of the nerve falls into two broad categories.One category is short stalks which came under the piriformis and then gave rise to all of the terminal branches of the nerve which spanned the muscle of the gluteus maximus.
