What is a lumbar discectomy?
A spinal disc is a sponge-like cushion located between the bones of the spine. Discs act as shock absorbers and allow the spine to flex. When a disc ruptures (herniates) it prolapses and presses on the nearby nerves, causing

What are the types of discectomy?
There are three ways a surgeon may choose to perform a discectomy:
- Open or conventional discectomy in which the surgeon makes a comparatively large incision to allow clear vision and also removes some muscle and ligament.
- Microdiscectomy is minimally invasive with a tiny incision. The surgeon does not remove any muscle or bone, but inserts a tube with a tiny camera/instruments to remove the damaged portion of the disc.
- Laser discectomy is in wider use now. This procedure requires no incision. Instead, the surgeon burns the prolapsed tissue away with a laser inserted through a needle.
When is a lumbar discectomy performed?
The symptoms of a herniated or prolapsed disc can often improve with:
A lumbar discectomy usually is performed only when the noninvasive methods listed above have failed to provide relief. It is likely to prove useful to who have a herniated lumbar disc who:
How is a lumbar discectomy performed?
- An anesthesiologist will administer anesthesia as the patient lies flat on their stomach.
- The anesthesiologist will continue to monitor the patient’s vital functions during the procedure.
- The surgeon will make an incision in the skin over the affected disc.
- Muscle and ligaments attached to the disc will be removed in the case of an open discectomy, or the surgeon will insert a tube with a microscope for a microdiscectomy.
- The surgeon will then remove the damaged tissue from the disc.
- They may also remove a part of the bone around the herniated disc if necessary.
- If a whole disc has to be removed, the surgeon might fill the space with bone from the patient’s pelvis or taken from a donor, or with synthetic bone.
- The surgeon will then suture the incision area.
- The anesthesiologist will bring the patient out of anesthesia and monitor until the patient’s condition is stable.
- The patient is usually discharged within a day.
What is the recovery time for a discectomy?
Patients are encouraged to start walking within a day or two. It is advisable to take a week or two off from work to allow healing to take place. After the surgery, for at least 2 to 4 weeks the patient should:
- not lift heavy objects
- sit for long periods
- bend or stretch excessively
How painful is a lumbar discectomy?
A lumbar discectomy is completely painless as it is done under anesthesia. The patient will feel nothing except the pinprick of the injection needle. Post-surgery, there is likely to be some amount of stiffness and pain that can be relieved with painkillers.
What are the risks and complications of a discectomy?
Discectomy is generally a safe option for patients who get no relief from non-surgical treatments. The risks may include:
What is the success rate of a discectomy?
Discectomy works well typically and it offers faster relief than other treatments. It still may not be the best choice for everyone and it is generally appropriate to exhaust all other options before choosing surgery.
Discectomy has been found to have about 90- to 95-percent success rate with only 5 percent of the patients experiencing recurring herniation.
