Sciatica
- Pathophysiology
- Peripheral Neuropathy due to sciatic nerve impingement
- Proximal or radicular impingement (e.g. Lumbar Disc Herniation)
- Distal impingement (e.g. Piriformis Syndrome)
- Peripheral Neuropathy due to sciatic nerve impingement
- Symptoms
- Low Back Pain with radiation into posterolateral buttock
- Causes
- Lumbar Disc Herniation (most common)
- Lumbar Spinal Stenosis

- Sponylolisthesis
Sciatica (C0036396) | |
|---|---|
| Definition (MSH) | A condition characterized by pain radiating from the back into the buttock and posterior/lateral aspects of the leg. Sciatica may be a manifestation of SCIATIC NEUROPATHY; RADICULOPATHY (involving the SPINAL NERVE ROOTS; L4, L5, S1, or S2, often associated with INTERVERTEBRAL DISK DISPLACEMENT); or lesions of the CAUDA EQUINA. |
| Definition (CSP) | syndrome characterized by pain radiating from the back into the buttock and into the lower extremity along its posterior or lateral aspect, and most commonly caused by protrusion of a low lumbar intervertebral disk; also used to refer to pain anywhere along the course of the sciatic nerve. |
