Piriformis syndrome occurs when your piriformis muscle compresses your sciatic nerve and results in inflammation. It can cause pain or numbness in your buttock and down the back of your leg.
Learn more about Piriformis syndrome, which is a neuromuscular disorder due to a compression of the sciatic nerve. Understand its causes, symptoms, and treatment methods.
The piriformis muscle (from Latin piriformis ' pear -shaped') is a flat, pyramidally-shaped muscle in the gluteal region of the lower limbs. It is one of the six muscles in the lateral rotator group.
Piriformis syndrome occurs when the piriformis muscle irritates the sciatic nerve, causing pain and numbness in the buttocks and leg. Conditions that cause similar symptoms include herniated discs, spinal stenosis, and sciatica.
The piriformis is a thick, flat muscle and the most superficial muscle among the deep gluteal muscles. It is part of the lateral rotators of the hip (obturator internus, superior and inferior gemelli, quadratus femoris, obturator externus, and gluteus maximus).
In this article we will discuss the anatomy of piriformis, as well as its neurovascular supply and function. In addition we discuss the clinical relevance of the muscle. This is a flat pyramid-shaped muscle that arises from the anterior surface of the sacrum, between the sacral foramina.
The piriformis muscle is a small, flat, and pear-shaped muscle located deep in the buttock. When overused or fatigued, it can spasm and irritate the nearby sciatic nerve, causing piriformis syndrome.
What do I need to know? What is my diagnosis? Piriformis is a muscle deep in the buttock which works to rotate the leg outwards. The sciatic nerve travels near or through the muscle and can get compressed at this point. Frequent signs and symptoms Tingling, numbness, burning in back of thigh, occasionally to the foot
