Spinal surgery - lumbar

Definition:

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

Alternative Names:
Lumbar spinal surgery
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 and may be caused by the following:

Injured disks that bulge out (slipped disk) between the vertebrae
Bone injuries (fractures)
Narrowing of the space between vertebrae (spinal stenosis)
Growths (tumors)
Pockets of infection (abscesses)
Pockets of blood (hematomas)

Patients with spinal pain in the neck or back are usually treated conservatively before surgery is considered. Bedrest, traction, anti-inflammatory medications (nonsteroid and steroid), physical therapy, braces, and exercise are often prescribed.

Maintaining good health, muscle strength, and body posture with appropriate rest and exercise help prevent unnecessary strain on the spine and muscles.

Lumbar spinal surgery is done while the patient is under general anesthesia (unconscious and pain-free). An incision is made over the troubled area. The bone that curves around and covers the spinal cord (lamina) is removed (laminectomy) and the tissue that is causing pressure on the nerve or spinal cord is removed.

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

Indications:

Symptoms of lumbar spine problems 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

If you are experiencing numbness in your groin region and problems with urinary or bowel control, contact your health care provider immediately. This could indicate cauda equina syndrome, which must be addressed as soon as possible.
