Piriformis Syndrome. Piriformis syndrome causes pain in the buttock which may radiate down the leg. It is due to the sciatic nerve being impinged by a tight piriformis muscle deep in the buttocks.he piriformis muscle is one of the small muscles deep in the buttocks that rotates the leg outwards. It runs from the sacrum bone at the bottom of the spine and attaches to the thigh bone or femur roughly near the outside crease of the buttocks.
Piriformis syndrome is an uncommon neuromuscular disorder caused by the compression or irritation of the sciatic nerve by the piriformis muscle. It results in pain in the buttocks and the leg and it is an unusual cause of sciatica.It is often misdiagnosed or unrecognised in patients with lower back pain.ommon causes of piriformis syndrome include: 1  Long-distance walking or running (overuse of the piriformis muscle). 2  Direct compression of the piriformis muscle (repetitive trauma). 3  Direct trauma to the buttocks resulting in sciatic nerve compression.
