Lumbar discectomy (spinal disc surgery) Neurosurgery
Lumbar discectomy is a surgery to remove part of a herniated disc in the lower back that is pressing on a nerve.
Overview
Lumbar discectomy is a surgery to remove part of a herniated disc in the lower back that is pressing on a nerve. It aims to relieve leg pain, numbness, or weakness caused by nerve compression, often called sciatica. During the procedure, the surgeon removes the disc fragment and any loose material that is irritating the nerve. This is commonly done through a small incision, sometimes with a microscope or specialized tools, to limit disruption of nearby tissues.
Also known as: Microdiscectomy, Lumbar microdiscectomy, Disc removal surgery, Herniated disc surgery
Preparation & Next Steps
Everything you need to know before and after your procedure
Before Care
- Confirm diagnosis with imaging such as MRI and review results with your surgical team
- Provide a complete list of medicines and supplements, including blood thinners and diabetes medicines
- Follow preoperative fasting instructions for anesthesia as provided by the surgical team
- Arrange a responsible adult to drive you home and stay with you the first night
- Plan time off work and help at home for the first few days after surgery
- Avoid smoking and nicotine exposure before surgery to support healing
- Set up a recovery space at home and remove trip hazards to reduce fall risk
- Shower as instructed before surgery and avoid lotions or creams near the incision area
- Bring your photo ID, insurance card, and any relevant imaging discs or reports
- Discuss questions about technique, incision size, expected hospital stay, and activity limits
After Care
- Keep the incision clean and dry as instructed and change dressings if directed
- Avoid soaking the incision in a bath, hot tub, or pool until it has healed
- Take short, frequent walks and gradually increase distance based on comfort
- Avoid heavy lifting, deep bending, or twisting early in recovery
- Use prescribed pain medicines as directed and avoid alcohol or driving if they cause drowsiness
- Stay hydrated and use fiber-rich foods or a stool softener to reduce constipation risk
- Protect the incision from friction and wear loose clothing
- Do not drive until you can brake safely and are not taking sedating pain medicines
- Attend scheduled follow-up to review healing, symptoms, and activity progression
- Contact the clinic for fever, worsening wound redness or drainage, increasing leg weakness, new numbness, or bowel or bladder changes
Clinical Information
Important medical details about this procedure
Indications
- Leg pain from a lumbar disc herniation that matches imaging findings
- Sciatica that does not improve with conservative care
- Progressive leg weakness or numbness due to nerve compression
- Severe pain limiting daily activities
- Cauda equina symptoms such as new bowel or bladder changes with saddle numbness
Alternatives
- Physical therapy and guided exercise
- Activity modification and time
- Nonsteroidal anti-inflammatory drugs
- Oral steroid taper when appropriate
- Epidural steroid injection
- Pain management strategies including heat or ice
Risks
- Infection
- Bleeding or hematoma
- Nerve injury or persistent numbness or weakness
- Dural tear with spinal fluid leak
- Recurrent disc herniation
- Ongoing back or leg pain
- Blood clots
- Anesthesia-related risks
Contraindications
- Active infection at the surgical site or systemic infection
- Uncontrolled bleeding disorder or use of anticoagulants that cannot be managed
- Severe medical conditions that make anesthesia unsafe
- Unclear diagnosis or symptoms that do not match imaging
Recovery Timeline
What to expect during your recovery
Many people notice leg pain relief soon after surgery. Incision soreness and back stiffness usually improve over several weeks. Return to routine activities commonly occurs within 2 to 6 weeks, depending on symptoms and job demands.
Typical Range
14–42 days
Return to Work
7–42 days
Recovery Milestones
Walk short distances indoors with support as needed
Increase walking to several brief sessions daily
Resume desk-based work if pain is manageable and mobility allows
Begin light exercise such as gentle stretching or stationary cycling if comfortable
Gradually add heavier lifting and higher-impact activity after clinical clearance
Frequently Asked Questions
Common questions and expert answers about this procedure
What is the difference between discectomy and microdiscectomy?
What is the difference between discectomy and microdiscectomy?
Both remove disc material pressing on a nerve. Microdiscectomy uses magnification and smaller instruments through a smaller incision.
Will the whole disc be removed?
Will the whole disc be removed?
Typically only the herniated fragment and any loose disc material are removed, leaving the rest of the disc in place.
Is lumbar discectomy an outpatient procedure?
Is lumbar discectomy an outpatient procedure?
Many people go home the same day. Some stay overnight based on recovery, pain control, or other medical needs.
What kind of anesthesia is used?
What kind of anesthesia is used?
General anesthesia is commonly used so you are asleep and do not feel pain during the procedure.
How big is the incision?
How big is the incision?
The incision is usually a few centimeters long. Size varies with body type, surgical approach, and the spinal level treated.
Can the herniation come back?
Can the herniation come back?
Recurrent herniation can occur at the treated level. Staying active, using good body mechanics, and following activity guidance may help reduce risk.
Will I need physical therapy?
Will I need physical therapy?
Some people benefit from therapy to restore flexibility, core strength, and posture. Timing and goals vary by symptoms and job demands.
When can I travel or fly?
When can I travel or fly?
Short car rides may be possible within days. Longer trips and flights are usually delayed until you can sit, walk, and manage pain comfortably.
