Definition of Spinal surgery - lumbar:

Lumbar spinal surgery is used to correct problems with the spinal bones (vertebrae), disks, or nerves of the lower back (lumbar spine).

• Slipped disk
• Spinal fusion
• Spinal surgery - cervical

Description:

The spine consists of bones (vertebrae) separated by soft cushions (disks). Pressure on the nerves that branch off the spinal cord can produce pain, numbness, tingling, or weakness.

Lumbar spinal surgery is done while you are under general anesthesia (unconscious and pain-free). A surgical cut is made over the area of the problem. The bone that curves around and covers the spinal cord and the tissue that presses on the nerve or spinal cord are removed.

The hole through which the nerve passes may be widened to prevent further pressure on the nerve. Sometimes, spinal fusion is necessary to stabilize the area.

Why the Procedure Is Performed:

Symptoms of lumbar spine problems that may require surgery at some point include:

• Pain that extends (radiates) from the back to the buttocks or back of thigh
• Pain that interferes with daily activities
• Weakness of legs or feet
• Numbness of legs, feet, or toes
• Loss of bowel or bladder control

It's important to note that patients with spinal pain in the neck or back are usually treated conservatively before surgery is considered. This includes bedrest, anti-inflammatory medications, physical therapy, braces, and exercise. Maintaining good health, muscle strength, and body posture with appropriate rest and exercise help prevent unnecessary strain on the spine and muscles.
