Quick Answer: What is a diskectomy?
A diskectomy is spine surgery that removes part or all of a damaged spinal disk, most often a herniated disk that is pressing on a nerve. It usually takes one to two hours and is often an outpatient procedure. Most people return to routine activities by six weeks, and lumbar diskectomies succeed in 60% to 90% of cases.
What the research says
Surgery eased long-standing sciatica faster than nonsurgical care. In a randomized trial of 128 people whose sciatica from a lumbar disk herniation had lasted 4 to 12 months, leg pain at 6 months scored 2.8 out of 10 after microdiskectomy versus 5.2 with nonsurgical care; 34% of the nonsurgical group later chose surgery. (Bailey et al., The New England Journal of Medicine, 2020) [2]
Endoscopic and microscopic diskectomy relieve nerve pressure equally well. A meta-analysis of 17 randomized trials with 2,238 patients found similar leg pain and disability results, while the full-endoscopic approach had less blood loss, about 23 days faster return to work and fewer wound infections, at the cost of more X-ray exposure. (Patel et al., Spine, 2026) [3]
Endoscopic diskectomy had fewer overall complications. Pooled data from 6 randomized trials showed overall complication rates of 5.5% with full-endoscopic lumbar diskectomy versus 10.4% with open or microdiskectomy, with no significant difference in recurrence. (Yang et al., World Neurosurgery, 2022) [4]
Key takeaways
A diskectomy removes all or part of a damaged spinal disk, usually for a herniated disk. [1]
About 60% to 90% of people with a herniated disk get better without surgery. [1]
The operation takes one to two hours, and minimally invasive diskectomy is often done as outpatient surgery. [1]
Recovery takes about one to four weeks; strenuous activity usually resumes around 12 weeks. [1]
Lumbar diskectomies succeed in 60% to 90% of cases, and the disk herniates again in 5% to 15%. [1]
What is a diskectomy?
Your spinal disks are cushions that sit between the vertebrae. A diskectomy is surgery to remove part or all of one of these disks. [1]
It is most often done for a herniated disk, where the soft gel inside the disk leaks out through a tear and presses on nearby nerves. Herniations most commonly affect the lower back (lumbar spine), less often the neck (cervical spine) and only rarely the middle back (thoracic spine). [1] Our guide to herniated disk symptoms and treatment explains the condition itself.
Types of diskectomy
Open and minimally invasive diskectomy reach the same disk through different-sized incisions.
Type | How it is done | Typical stay |
Open (standard) diskectomy | A larger incision of about 1 to 2 inches; back muscles are moved aside | May need a day or two in the hospital |
Minimally invasive diskectomy | An incision under 1 inch, dilators and an endoscope; includes micro-endoscopic and full-endoscopic versions | Often home the same day |
Anterior cervical diskectomy and fusion (ACDF) | Approached from the front of the neck, followed by a spinal fusion | Depends on the surgery |
Sources: [1]
A diskectomy can treat one disk (single-level) or several (multi-level). [1] For the neck operation, see our guide to ACDF surgery and our overview of spinal fusion surgery.
Who needs a diskectomy?
Most people with a herniated disk don't need surgery: about 60% to 90% recover with nonsurgical care such as anti-inflammatory medicines (NSAIDs), epidural steroid injections and physical therapy. [1]
Your provider may suggest a diskectomy when symptoms are severe or don't go away, for example: [1]
Leg or arm pain or numbness that interferes with daily tasks
Severe muscle weakness
Sciatica, nerve pain that runs down the leg
Emergency: cauda equina syndrome, which causes sudden weakness or numbness along with bladder or bowel problems, needs immediate surgery. [1] Learn more in our sciatica guide.
How do you prepare for a diskectomy?
Before surgery your surgeon will usually: [1]
Do a physical exam and review your medical history
Review all of your medicines
Order imaging, such as an X-ray, a myelogram or an MRI
Don't stop any medicine without your provider's approval. Tell your care team if you use tobacco, because nicotine can interfere with healing; you may be asked to quit at least four weeks before surgery. [1]
What happens during a diskectomy?
A diskectomy usually takes one to two hours. [1]
The main steps of a diskectomy.
You receive anesthesia: general anesthesia so you are asleep, or local anesthesia so you are awake but feel no pain.
For open surgery, the surgeon makes an incision of about 1 to 2 inches over the affected disk. Minimally invasive surgery uses an incision of less than 1 inch guided by fluoroscopy (real-time X-ray).
The surgeon removes all or part of the damaged disk.
The incision is closed with stitches, staples or skin glue.

Diskectomy at a glance
Item | Typical detail |
Anesthesia | General, or local in some cases |
Incision | About 1 to 2 inches (open) or under 1 inch (minimally invasive) |
Imaging during surgery | Fluoroscopy for minimally invasive surgery |
Length of surgery | One to two hours |
Hospital stay | Often same day (minimally invasive); a day or two (open) |
Sources: [1]
What happens after a diskectomy?
Your care team monitors your vital signs until the anesthesia wears off and usually gives you pain medicine. Minimally invasive diskectomies are often outpatient, so you can go home the same day with someone to drive you. Open surgery may mean a day or two in the hospital. [1]
Before you leave, you receive instructions on caring for your incision, which activities are safe and which warning signs to watch for. Your provider may also recommend physical therapy. [1]
How long is recovery from a diskectomy?
Recovery takes about one to four weeks, depending on how severe your symptoms were before surgery, your general health and how closely you follow your aftercare. Surgeons generally advise avoiding significant bending, lifting and twisting for three to six weeks. [1]

What are the benefits and risks of a diskectomy?
Lumbar diskectomies have a success rate between 60% and 90%, although results depend on several factors, and your surgeon can tell you what to expect in your case. [1]
Serious complications are rare, but possible risks include: [1]
Risk | What it means |
Reaction to anesthesia | An unwanted response to the anesthetic medicines |
Infection or bleeding | Germs in the wound, or blood loss during or after surgery |
Blood clots | Clots that can form after surgery |
Nerve damage | Injury to a nearby nerve |
Cerebrospinal fluid leak | Leakage of the fluid around the spinal cord |
No pain relief | Symptoms that do not improve |
Repeat herniation | The disk herniates again and needs revision surgery in 5% to 15% of cases |
Spinal instability | An unstable spine that may need more surgery |
Sources: [1]
If nerve pressure comes from bone rather than disk material, a surgeon may suggest a related operation such as a laminectomy or a laminotomy.
When should you call a doctor after a diskectomy?
Contact your healthcare provider promptly if you notice: [1]
Signs of incision infection, such as swelling, skin discoloration or fever
Severe or worsening pain
Sudden numbness or muscle weakness
Difficulty breathing
Difficulty urinating or having a bowel movement
Conclusion
A diskectomy removes all or part of a damaged spinal disk to take pressure off a nerve, most often for a herniated disk that hasn't improved with nonsurgical care. It usually takes one to two hours, is often done as outpatient surgery when minimally invasive tools are used, and succeeds in 60% to 90% of lumbar cases. [1]
If back, neck, arm or leg nerve pain is limiting your daily life, ask your provider whether you have tried enough nonsurgical options and whether a diskectomy could help you.
