Sciatica and key hole spine surgery


WHAT ARE THE CAUSES OF SCIATICA? : Explained by brain tumor surgeon Dr.Kalyan Bommakanti, M.Ch

Sciatica is a term used to describe pain in the leg caused by compression or irritation of the sciatic nerve. The Sciatic nerve is the longest nerve present in the body that travels through the lower back to the leg. Usually, sciatica affects only one side of the body; it can also affect both sides.

Sciatica may be caused by various conditions, including:


The facet joints are the ones located on the posterior aspect of the spine. As these joints are in a continuous weight-bearing position, the cartilage around their ends can tear down and become thin followed by friction and inflammation of the affected joint. This is called Facet joint arthritis.

Facet joint problems in the lumbar region can cause low back pain and can cause sharp and shooting radicular leg pain (sciatica) if there is the involvement of the sciatic nerve. It can also cause muscle weakness and fatigue in the area involved.


Spinal stenosis is narrowing of the spinal canal. It causes a reduction in the space for the structures passing through, hence impinging them. It is most commonly found in older adults of 60 plus age, and in the elderly population, lateral stenosis may be common.


It is the natural breakdown of the discs present between the vertebras. Degenerative intervertebral discs tend to produce inflammatory proteins, causing inflammation of the sciatic nerve. The discs are reduced in size after the breakdown, causing spinal stenosis as well.


Spondylolisthesis occurs when a vertebra slips out of alignment over the other, causing the narrowing of the exit of the spine. The protruded bone pinches the sciatic nerve. It can be caused by the degeneration of the vertebra/disc or fracture. Spondylolisthesis can cause bilateral sciatica and is more common in young adults.


Lumbar osteoarthritis is a degenerative disease that causes cartilage deterioration in the vertebral joints. It also causes inflammation of the joints, which results in pain and stiffness. The inflamed facet joints eventually compress the sciatic nerve.
