Spinal stenosis is a condition in which the space for the spinal cord or nerves gets narrowed and results in spine decompression. It mostly occurs in the lower back and neck, and results from physical wear and tear of the spine bones called osteoarthritis.
The stenosis is categorised into two types, which include cervical stenosis (narrowing occurs in part of the spine and neck), and lumbar stenosis (narrowing occurs in part of the spine and lower back). Lumbar stenosis surgery is performed to widen the space for the spinal cord or nerves.

Based on the diagnosis, you will be provided with the appropriate treatment options, which may include:
Laminectomy:Laminectomy is a standard procedure in which your surgeon removes the additional bone spurs and ligaments that are compressing the spinal nerves are eliminated using small incisions.
Spinal Fusion: Spinal fusion is performed aside with laminectomy. In this procedure, the vertebrae joints are joined together to reduce your spine movement. In the spine fusion, your surgeon may use either metal screws, rods, or other hardware while joining your vertebrae.
Foraminotomy: Foraminotomy is a surgical procedure to expand the vertebrae where the nerve roots branch out to the rest of your body.
