Compression of the sciatic nerve can cause any of the above-cited symptoms. Rarely is nerve damage permanent and paralysis is seldom a danger as the spinal cord ends before the first lumbar vertebra. However, increasing trunk or leg weakness, or bladder and/or bowel incontinence is an indication of Cauda Equina Syndrome, a serious disorder requiring emergency treatment.

Lumbar spine disorders known to cause sciatic nerve compression include the following:

Herniated discs are the most common cause of sciatica in the lumbar spine.
Degenerative Disc Disease, a natural biological process associated with aging, is known to cause disc weakness that can be a precursor to a disc herniation.
Lumbar Spinal Stenosis is a narrowing of one or more neural passageways due to disc degeneration and/or facet arthritis. The sciatic nerve may become impinged as a result of these changes.
Isthmic Spondylolisthesis results from a stress fracture often at the 5th lumbar vertebra (L5). The fracture combined with disc space collapse may allow the vertebra to slip forward on the first sacral segment (S1). The slippage may cause the L5 nerve root to become pinched as it leaves the spine.

Possible Complications

Partial or complete loss of leg movement.
Partial or complete loss of sensation in the leg.
Recurrent or unnoticed injury to the leg .
