title: Piriformis muscle syndrome.
abstract: Sciatica is characterized by radiating pain from the sacro-lumbar region to the buttocks and down to the lower limb. The causes of sciatica usually relate to degenerative changes in the spine and lesions to the intervertebral discs. Secondary symptomatic sciatica may by caused by metastases to the vertebra, tuberculosis of the spine, tumors located inside the vertebral channel, or entrapment of the sciatic nerve in the piriformis muscle. The piriformis syndrome is primarily caused by fall injury, but other causes are possible, including pyomyositis, dystonia musculorum deformans, and fibrosis after deep injections. Secondary causes like irritation of the sacroiliac joint or lump near the sciatic notch have been described. In the general practice the so-called posttraumatic piriformis muscle syndrome is common. The right treatment can be started following a thorough investigation into the cause of symptoms.
