Lumbar spinal stenosis involves the narrowing of the spinal canal in the lower back, often causing pain, numbness, and weakness. While conservative treatments can help, surgery may be necessary for severe cases. Surgical options like decompression or spinal fusion aim to relieve nerve compression and stabilize the spine.

Spinal stenosis is a medical condition where the spinal canal, which houses the spinal cord and nerve roots, becomes narrowed. This narrowing can lead to compression of the spinal cord or nerve roots, causing a range of symptoms such as persistent pain, numbness, tingling, and weakness. These symptoms can occur in various parts of the body, including the back, legs, and arms, and may worsen over time.
