What is a laminectomy?
Back or neck pain that interferes with normal daily activities may need surgery for
treatment. Laminectomy is a type of surgery in which a surgeon removes part or all
of the vertebral bone (lamina). This helps ease pressure on the spinal cord or the
nerve roots that may be caused by injury, herniated disk, narrowing of the canal (spinal
stenosis), or tumors. A laminectomy is considered only after other medical treatments
have not worked.
Why might I need a laminectomy?
Low back or neck pain can range from mild, dull, and annoying to persistent, severe,
and disabling. Pain in the spine can restrict your ability to move and function. Laminectomy
may be done to ease pressure on the spinal nerves, treat a disk problem, or remove
a tumor from the spine.
One common reason for having a laminectomy is a herniated disk in the spine.
A disk may be displaced or damaged because of injury or wear and tear. When the disk
presses on the spinal nerves, this causes pain, and sometimes numbness or weakness.
The numbness or weakness will be felt in the body part where the nerve is involved,
often the arms or legs. The most common symptom of a herniated disk is sciatica. This
is a sharp, shooting pain along the sciatic nerve, extending from the buttocks to
the thigh and down the back of the leg.
If medical treatments no longer work, surgery may be a choice. Some medical treatments
for pain may include:
Changes in activity
Medicines, such as muscle relaxants, anti-inflammatory medicines, and pain relievers
Physical rehabilitation, physical therapy, or both
Weight loss (if overweight)
Assistive devices, such as mechanical back supports
Laminectomy is usually done for back or neck pain that continues after medical treatment.
Or it's done when the pain is accompanied by symptoms of nerve damage, such as numbness
or weakness in the arms or legs. Loss of bowel or bladder control from pressure in
the cervical or lumbar spine also usually needs surgery.
There may be other reasons for your healthcare provider to recommend a laminectomy.
What are the risks of a laminectomy?
As with any surgical procedure, complications can occur. Some possible complications
Blood clots in the legs or lungs
Spinal cord or nerve root injury
Risks linked to the use of general anesthesia
Nerve or blood vessels in the area of surgery may be injured. This can cause weakness
or numbness. The pain may not be eased by the surgery or may become worse, although
this is rare.
There may be other risks depending on your specific health condition. Be sure to discuss
any concerns with your healthcare provider before the surgery.
How do I get ready for a laminectomy?
Your healthcare provider will explain the surgery to you and offer you the chance
to ask any questions that you might have about the procedure.
You will be asked to sign a consent form that gives your permission to do the surgery.
Read the form carefully and ask questions if something is not clear.
In addition to a complete health history, your healthcare provider may do a physical
exam to make sure that you are in good health before undergoing the procedure. You
may have blood tests or other diagnostic tests.
Tell your healthcare provider if you are sensitive to or are allergic to any medicines,
latex, tape, and anesthesia medicines (local and general).
Tell your healthcare provider of all prescribed and over-the-counter medicines and
herbal supplements that you are taking.
Tell your healthcare provider if you have a history of bleeding disorders or if you
are taking any blood-thinning (anticoagulant) medicines, aspirin, or other medicines
that affect blood clotting. You may be told to stop these medicines before the procedure.
If you are pregnant or think you could be, tell your healthcare provider.
Follow any directions you are given for not eating or drinking before the surgery.
You may get a sedative before the surgery to help you relax.
You may meet with a physical therapist before your surgery to discuss rehabilitation.
Certain activities may be limited after your surgery. Arrange for someone to help
you for a few days with the household activities and driving.
Based on your health condition, your healthcare provider may have other instructions
What happens during a laminectomy?
A laminectomy usually requires a stay in a hospital. Procedures may vary depending
on your condition and your doctor’s practices.
A laminectomy may be done while you are asleep under general anesthesia. Or it may
be done while you are awake under spinal anesthesia. If spinal anesthesia is used,
you will have no feeling from your waist down. Newer techniques are being developed
that may allow a laminectomy to be done under local anesthesia as an outpatient. Your
doctor will discuss this with you in advance.
Generally, a laminectomy follows this process:
You will be asked to remove clothing and will be given a gown to wear.
An IV (intravenous) line may be started in your arm or hand.
Once you are under anesthesia, a urinary drainage catheter may be inserted.
If the surgical site is covered with extra hair, the hair may be clipped off.
You will be positioned either on your side or belly on the operating table.
The anesthesiologist will continuously watch your heart rate, blood pressure, breathing,
and blood oxygen level during the surgery.
The healthcare staff will clean the skin over the surgical site with an antiseptic
The surgeon will make a cut (incision) over the selected vertebra.
The surgeon will spread the muscles apart.
The surgeon removes the bony arch of the posterior part of the vertebra (lamina) to
ease the pressure on the nerves in the area. This may involve removing bone spurs
or growths, or removing all or part of a disk.
In some cases, spinal fusion may be done at the same time. During a spinal fusion,
the surgeon will connect 2 or more bones in your spine.
The incision will be closed with stitches or surgical staples.
A sterile bandage or dressing will be applied.
What happens after a laminectomy?
In the hospital
After the surgery, you will be taken to the recovery room for observation. Once your
blood pressure, pulse, and breathing are stable and you are alert, you will be taken
to your hospital room. Laminectomy usually requires that you stay in the hospital
one or more days.
You will most likely start getting out of bed and walking the evening of your surgery.
Your pain will be controlled with medicines so that you can take part in the exercise.
You may be given an exercise plan to follow both in the hospital and after discharge.
Once you are at home, it's important to keep the surgical incision area clean and
dry. Your healthcare provider will give you specific bathing instructions. The surgical
staples or stitches are removed during a follow-up office visit.
Take a pain reliever for soreness as recommended by your healthcare provider. Aspirin
or certain other pain medicines may increase the chance of bleeding so be sure to
take only recommended medicines.
Tell your healthcare provider about any of the following:
Redness, swelling, bleeding, or other drainage from the incision site
Increased pain around the incision site
Numbness in your legs, back, or buttocks
Trouble urinating or loss of control of your bladder or bowel
Don't drive until your healthcare provider tells you it's OK. Don't bend over to pick
up objects or arch your back. Your provider may tell you to limit other activities.
Your healthcare provider may give you other instructions after the procedure, depending
on your particular situation.
