Lumbar discectomy is a type of surgery to fix a disc in the lower back. This surgery uses smaller cuts (incisions) than an open lumbar discectomy.
Your backbone, or spinal column, is made up of a chain of bones called the vertebrae. Your spinal cord runs through the spinal column. The bones help protect the cord from injury. Discs sit between each vertebra to provide cushioning and support. Large nerves called nerve roots lead from the spinal cord through small holes in the bones called foramen. These nerve roots send and receive signals to and from the body. The signals are sent to and from your brain through the spinal cord.
Sometimes the outer wall of one of these discs may dry out and weaken with age or injury. When this happens, the soft, inner part of the disc bulges out. This is called a herniated or bulging disc. This bulging disc can press on the spinal cord and cause symptoms such as pain, tingling, or weakness in a nearby part of the body.
During a minimally invasive lumbar discectomy, an orthopedic surgeon takes out part of the damaged disc. This helps ease the pressure on the spinal cord. Your surgeon can use different methods to do this. With one method, your surgeon inserts a small tube through the skin on your back, between the vertebrae and into the space with the herniated disc. He or she then inserts tiny tools through the tube to remove a part of the disc. Or a laser may be used to remove part of the disc. Unlike an open lumbar discectomy, the surgeon makes only a very small skin incision and does not remove any bone or muscle.

Before Lumbar Discectomy Surgery
Why might I need a lumbar discectomy?
You may need this surgery if you have a herniated disc in your lower back that is causing symptoms. The symptoms may include weakness, pain, or tingling in the back area and in one of your legs.
Lumbar discectomy can’t be used to treat all cases of back pain. And not everyone with a herniated disc needs a lumbar discectomy. Your healthcare provider might advise the surgery if you’ve tried other treatments but still have severe symptoms. Other treatments to try first include physical therapy and anti-inflammatory medicines.
Talk with your provider about the risks and benefits of minimally invasive surgery compared to open surgery. Minimally invasive surgery may lead to less pain and faster recovery. But not all surgery centers can use this method.
What are the risks of a lumbar discectomy?
Every surgery has risks. Risks for this surgery include:
. Excess bleeding
. Blood clots
. Injury to nearby nerves
. Reaction to anesthetic agents
. Only short-term (temporary) relief and need for another surgery
Your risks may vary depending on your age and your general health. Talk with your provider about the risks that most apply to you.
How do I get ready for a lumbar discectomy?
Ask your healthcare provider how you should plan to prepare for your procedure. Ask if you should stop taking any medicines ahead of time, like blood thinners. Do not eat or drink after midnight the night before your procedure.
Your provider may order other imaging tests of your spine, such as an MRI.
During Lumbar Discectomy Surgery
What happens during a lumbar discectomy?

After Lumbar Discectomy Surgery
What happens after a lumbar discectomy?
The surgery is usually an outpatient procedure. This means you can go home the same day. You will probably need to stay for a couple of hours after the procedure. Make sure you have someone who can drive you home.
Your healthcare provider will give you instructions about how you can use your back. You might need to limit lifting or bending. Your provider might have you wear a back brace for a limited time after the procedure. Most people can go back to work within a week or so. You may need physical therapy after surgery to help strengthen your back.
You may see some fluid draining from your small incision. This is normal. Tell your provider right away if there is a large amount of drainage from the incision site. Also call your provider if you develop a fever or if you have a lot of pain in the area.
Sometimes the procedure causes slightly more pain for a while. But you can take pain medicines to ease the pain. Usually this goes away quickly. Your pain should become less than it was before your surgery.
Make sure to follow all your provider’s instructions and keep your follow-up appointments.
