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.
The sciatic nerve, which is the longest nerve in a person’s body, runs underneath the piriformis. It travels from the spinal cord all the way down to a person’s feet. Piriformis syndrome can ...

Nerve compression syndrome, or compression neuropathy, or nerve entrapment syndrome, is a medical condition caused by chronic, direct pressure on a peripheral nerve. [1] It is known colloquially as a trapped nerve , though this may also refer to nerve root compression (by a herniated disc , for example).
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.
What is piriformis syndrome? Piriformis syndrome is a rare neuromuscular condition that happens when the piriformis muscle in the butt presses on the sciatic nerve, according to the Genetic and ...
The inferior gluteal nerve entered the deep surface of gluteus maximus very inferiorly. At the lower border of the piriformis muscle, the nerve turns backward and divides into upward and downward diverging branches, which enter the gluteus maximus. The nerve may also send a branch to the posterior femoral cutaneous nerve. [3]
