Piriformis syndrome is a condition which is believed to result from nerve compression at the sciatic nerve by the piriformis muscle. [2] [5] It is a specific case of deep gluteal syndrome. [6] The largest and most bulky nerve in the human body is the sciatic nerve. Starting at its origin it is 2 cm wide and 0.5 cm thick.
Piriformis syndrome can occur on one or both sides of the body. It can be caused by injury, swelling, muscle spasms or scar tissue in the piriformis. Anything that makes the piriformis press on ...
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.
The main epidemiological data available is on piriformis syndrome. Due to challenges in defining and diagnosing piriformis syndrome, attempts at quantifying its prevalence have led to conflicting estimates. Recent estimates for the prevalence of piriformis syndrome are 6% and 17% of all patients with low back pain / sciatica. [8]
According to the National Institutes of Health (NIH), piriformis syndrome "is a rare neuromuscular condition that occurs when the piriformis muscle in the buttocks presses on the sciatic nerve ...
Andie MacDowell is opening up about being diagnosed with piriformis syndrome.. The Four Weddings and a Funeral actress, 66, shared on the Thursday, January 23, episode of The Drew Barrymore Show ...
Piriformis syndrome is a condition that, depending on the analysis, varies from a "very rare" cause to contributing up to 8% of low back or buttock pain. [16] In 17% of people, the sciatic nerve runs through the piriformis muscle rather than beneath it. [15]
The biomechanical relationship between the sacroiliac joint, the piriformis muscle (see "piriformis syndrome"), and the sciatic nerve had not yet been discovered. [18] In 1934, the work of Mixter and Barr shifted all emphasis in research and treatment from the sacroiliac to the herniated intervertebral disc, namely lumbar discs. [30]
