Laminectomy (decompression surgery)
A laminectomy is surgery to remove the lamina, part of the bone that makes up a vertebra, to take pressure off the spinal nerves or spinal cord. It is often done for spinal stenosis; MedlinePlus says surgery may help when symptoms become more severe and interfere with daily life or work. Most people go home the same day or within 1 to 2 days (MedlinePlus).
Overview
A laminectomy opens up the spinal canal so the nerves have more room. Bone spurs, disc fragments or other tissue pressing on the nerves may be removed at the same time (MedlinePlus; AAOS OrthoInfo).
It is also called lumbar decompression or decompressive laminectomy, and it may be done together with a diskectomy, a foraminotomy or a spinal fusion (MedlinePlus).
It can be done as open surgery through one larger incision, or with a minimally invasive method using several smaller incisions (AAOS OrthoInfo).
Why it is done
- Often to treat spinal stenosis, a narrowing of the spinal column (MedlinePlus)
- Symptoms it may be done for include pain or numbness in one or both legs, and weakness or heaviness in the buttocks or legs (MedlinePlus)
- Problems emptying or controlling the bladder or bowel
- When symptoms become more severe and interfere with daily life or work, MedlinePlus says surgery may help. The AAOS says stenosis surgery is generally reserved for people whose quality of life is poor because of pain and weakness
What happens
- You are given general anaesthesia, so you are asleep and feel no pain
- The surgeon makes an incision in the middle of the back or neck and moves the muscles aside
- Part or all of the lamina is removed, and the surgeon may also remove small disc fragments, bone spurs or other soft tissue
- The surgery takes 1 to 3 hours (MedlinePlus)
Recovery
- If you did not also have a fusion, MedlinePlus says your provider will encourage you to get up and walk as soon as the anaesthesia wears off
- Most people go home the same day or 1 to 2 days after surgery (MedlinePlus)
- MedlinePlus says you should be able to drive within a week or two and return to light work after about 4 weeks, especially if you did not have a fusion
- The AAOS says healthy people who have decompression alone may return to normal activities after a few weeks, and that most people need some physical therapy to strengthen their backs
Risks
- Infection in the wound or the vertebral bones
- Damage to a spinal nerve, causing weakness, pain or loss of feeling
- Partial or no relief of pain, or back pain returning in the future
- A spinal fluid leak that can cause headaches
- General surgical risks: reactions to medicines, breathing problems, bleeding and blood clots
- If a fusion is also done, the spine above and below it is more likely to have problems later (MedlinePlus)
Results
MedlinePlus says laminectomy for spinal stenosis often provides full or some relief from symptoms. Future spine problems are possible after any spine surgery.
What it costs, and how to find out
SpinalCare does not publish a price for these procedures, because no cited source gives one figure that would apply to you.
Since January 1, 2021, US hospitals have had to publish their standard charges online, free of charge. That includes the rates they negotiate with insurance companies and the discounted price they will accept if you pay in cash (CMS).
Hospitals must also show prices for at least 300 "shoppable" services that can be planned in advance, in a consumer-friendly format. The rule applies to hospitals. CMS suggests checking these charges before you receive care, and using Medicare's Care Compare to look at quality information for over 4,000 Medicare-certified hospitals.

Frequently asked
- How long does it take to recover from a laminectomy?
- Most people go home the same day or 1 to 2 days later. MedlinePlus says you should be able to drive within a week or two and return to light work after about 4 weeks, especially without a fusion, and the AAOS says healthy people who have decompression alone may return to normal activities after a few weeks.
- What else is a laminectomy called?
- MedlinePlus lists lumbar decompression and decompressive laminectomy as other names for a laminectomy.
- Will a laminectomy fix my symptoms?
- MedlinePlus says it often provides full or some relief from spinal stenosis symptoms, but lists partial or no relief, and back pain returning later, among the risks.
- How much does a laminectomy cost?
- SpinalCare does not publish a price, because no cited source gives one figure that would apply to you. CMS says US hospitals must publish the rates they negotiate with insurance companies and a separate cash price, so you can compare hospitals. The rule applies to hospitals.
