Lumbar Spine
Lumbar Microdiscectomy
A focused outpatient operation to relieve pressure on a single nerve root from a herniated lumbar disc.
What it is
A microdiscectomy is a focused operation that removes the small fragment of disc material pressing on a single lumbar nerve root. The disc itself stays in place — only the herniated piece is removed.
It is performed through a small incision in the lower back, typically with the operating microscope or a tubular retractor. Most patients are home the same day.
Why this procedure when surgery is needed
When leg pain from a herniated disc has not improved with physical therapy, anti-inflammatories, and an epidural injection — and when the imaging clearly matches the symptoms — a microdiscectomy is one of the most reliable operations in spine surgery. Pain relief is typically immediate and durable.
The procedure is conservative by design. We do not fuse, instrument, or remove the disc itself. We only remove what is causing the nerve compression.
What to expect
Surgery takes about an hour. You go home the same day.
Most patients walk that afternoon, return to desk work in 1–2 weeks, and return to driving when off narcotics — usually within a week.
Heavy lifting and bending are restricted for the first 4–6 weeks while the disc heals.
Long-term: most patients have lasting relief. Re-herniation — the same disc herniating again — is uncommon, but it is the most common reason a patient may need a second operation.
Risks and how we reduce them
Microdiscectomy is one of the more predictable operations in spine surgery, but no operation is without risk — here is an honest account of what is common and temporary versus what is rare but serious.
Expected, temporary effects
Incisional and back soreness. Soreness at the small incision and in the surrounding back muscles for the first days to weeks, which settles as the tissue heals.
Lingering numbness or tingling. A nerve that has been compressed for a while can take weeks to months to fully quiet down, so some numbness or tingling may persist even after the leg pain is gone.
Serious risks
Re-herniation. The same disc can herniate again. It is uncommon, but it is the most common reason a patient may need a second operation.
Dural tear (CSF leak). A small tear in the lining around the nerves can occur and is repaired at the time of surgery; it occasionally requires a short period of lying flat afterward.
Nerve-root injury. Direct injury to the nerve root is rare but can cause new weakness, numbness, or pain. The operating microscope and careful technique are used to minimize this risk.
Infection. Wound or deeper infection is uncommon and is reduced with sterile technique and antibiotics when appropriate.
Your recovery, phase by phase
A general timeline for this procedure. Your surgeon’s own protocol takes precedence — use this to know what to expect and what questions to ask at each visit.
Before surgery
- Stopping nicotine before surgery improves wound healing and lowers your infection risk — the earlier you stop, the better.
- Bring a complete list of medications and supplements to your pre-anesthesia visit. Blood thinners, NSAIDs, GLP-1 medications, and some supplements are held on a schedule the team sets for you.
- The night before and the morning of surgery you shower with Hibiclens (chlorhexidine soap) and stop eating after midnight; the anesthesia team tells you when to stop clear liquids.
- Because this is an outpatient operation, arrange a ride home for the same day and someone to stay with you the first night.
The day of surgery
- Arrive about two hours early to check in, change, have an IV placed, and meet Dr. Tuchek, the anesthesiologist, and the OR nurses.
- The operation is done under general anesthesia — you are fully asleep — and takes about an hour.
- You are positioned face-down (prone) while asleep; the team pads and protects your pressure points throughout.
- Your family waits nearby; Dr. Tuchek speaks with them as soon as the operation is finished, before you are fully awake.
In the recovery unit
- You recover in the PACU as the anesthesia wears off. A sore throat, grogginess, and mild nausea are common and treated actively.
- Most patients get up and walk the same afternoon with a nurse or physical therapist.
- This is typically a same-day surgery — most people go home once they are awake, walking, and comfortable on oral pain medication.
The first two weeks
- Leg pain from the pinched nerve is often relieved right away; incisional soreness and some back stiffness are normal and improve week over week.
- Short, frequent walks are the main activity. Avoid heavy lifting, repeated bending, and twisting while the disc heals.
- Keep the incision clean and dry, and follow the specific dressing and showering instructions in your discharge paperwork.
- Many patients return to desk work within one to two weeks. You can drive again once you are off narcotic pain medication and can move comfortably — confirm the timing with your surgeon.
Weeks 2 to 6
- Activity is increased gradually. Lifting, bending, and twisting limits usually stay in place for the first four to six weeks — follow the specific protocol your surgeon gives you.
- Walking distance and stamina build steadily; some surgeons add gentle core physical therapy during this window.
- You will have a follow-up visit to check the incision and your progress.
Long-term recovery
- Most patients have lasting relief of their leg pain. The disc itself is left in place, so a fragment can re-herniate over time — call the office if the old leg pain returns.
- Once cleared by your surgeon, patients typically return to full activity, including exercise and heavier work, on their surgeon’s timeline.
Milestone checkpoints
| Window | Milestone | What to expect |
|---|---|---|
| Post-op days 1-3 | Start walking | Short, frequent walks starting the day of surgery — up and moving every 1-2 hours during the day. Walking guards against blood clots, pneumonia, and constipation; long stretches lying flat work against you. |
| Post-op days 1-3 | Shower | Keep the incision dry for the first 48 hours. After that a normal shower is generally fine unless you are told otherwise — let water run over the incision, no scrubbing, and pat dry. No soaking, baths, or swimming. Follow your discharge instructions. |
| Checkpoint | Driving | Resume only once you are off all narcotic pain medication and can comfortably turn to look and react in an emergency — often within about a week after a microdiscectomy. Your surgeon confirms this at your first post-op visit. |
| Checkpoint | Return to work | Desk or remote work is typically possible in about 1-2 weeks; jobs with standing, lifting, or twisting take longer. Your surgeon clears the timeline that fits your operation and your job. |
| Week 6 | Lifting and bending ease up | Heavy lifting, bending, and twisting are usually limited for the first 4-6 weeks while the disc heals, then gradually progressed. Follow your surgeon's specific activity protocol rather than a fixed date. |
| Week 2 | First post-op visit | A wound check about two weeks after surgery — sutures removed if needed, and a review of how recovery is going. |
| Any time | When to call | Call the office for fever, drainage or spreading redness at the incision, or calf pain or one-sided leg swelling. New or worsening leg weakness or numbness, or any loss of bowel or bladder control, is an emergency — call 911. The clinic phone line is not an emergency line. |

Prepare for this surgery
Recover from this surgery
Approach
- Tubular or microscope-assisted minimally invasive technique
- Single small incision, typically 1 inch
- Outpatient, general anesthesia
- Operating microscope used for nerve visualization
Typical indications
- Single-level lumbar disc herniation with matching radicular symptoms
- Failed 6+ weeks of appropriate conservative care
- Progressive motor weakness
- Cauda equina syndrome (urgent indication)
Alternatives we considered
- Continued physical therapy and time — many herniations resolve over 6–12 weeks
- Epidural steroid injection for severe inflammatory pain
- Lumbar laminectomy if there is broader stenosis as well
- Conservative observation if symptoms are mild and stable
