“Sciatica” is the common or lay term for lumbar radiculopathy. Sciatica refers to compression, irritation, disease or dysfunction of the spinal nerve roots often causing pain, numbness, or weakness into the legs (the area innervated by the sciatic nerve).
What are the causes?
Sciatica is most typically caused by a herniated disc pressing on a nerve root. Less commonly, roots are compressed by an enlarged facet joint or slipped disc (spondylolisthesis).
What treatment options are available?
See treatment options for herniated disc disease.
