What is the piriformis muscle?
The piriformis is a flat, pear-shaped muscle located deep in the gluteal region. The piriformis muscle originates from the anterior surface of the sacrum, the greater sciatic foramen, and the sacrotuberous ligament, inserting onto the greater trochanter of the femur. This muscle is responsible for external rotation and abduction of the hip joint.
Importantly, the sciatic nerve typically passes inferior to the piriformis through the greater sciatic foramen, which can lead to piriformis syndrome when the nerve is compressed. The piriformis also interacts with structures like the superior gluteal nerve, inferior gluteal nerve, and inferior gluteal artery, affecting the function and health of the hip joint and surrounding areas. It is situated near the gluteus medius and obturator internus muscles, playing a role in challenging neuropathic pain syndromes.

Commonly asked questions
The gluteal muscles, often referred to as the "glutes," consist of three major muscles located in the buttocks: the gluteus maximus, gluteus medius, and gluteus minimus. Each muscle plays a crucial role in various movements of the hip and thigh, contributing to activities such as walking, running, and climbing.
The piriformis muscle is a small muscle located deep within the buttocks. It extends from the anterior part of the sacrum to the upper border of the greater trochanter of the femur. It passes through the greater sciatic notch and lies beneath the gluteus maximus muscle, near the posterior margin of the pelvis.
The gluteus medius and gluteus maximus are key players in the stability and movement of the hip. The gluteus maximus is the largest and most superficial of the gluteal muscles, primarily responsible for the extension, outward rotation, and abduction of the hip. The gluteus medius, located more laterally, assists in the abduction and medial rotation of the hip and helps stabilize the pelvis during walking. The piriformis muscles work closely with these muscles to facilitate smooth and coordinated movement of the hip and thigh.
