Lumbar microdiscectomy—also called lumbar discectomy—removes the herniated portion of a disc that compresses a spinal nerve root, most often for lumbar disc herniation with sciatica. Using magnification through a small incision, the surgeon relieves leg pain while preserving healthy disc tissue whenever possible.

Symptoms and Signs of Lumbar Discectomy (Microdiscectomy)
Lumbar disc herniation often causes sharp sciatica—leg pain, numbness, or weakness that follows the affected nerve root. Symptoms may worsen with sitting, coughing, sneezing, or bending and may improve when lying down or changing position.
Radicular leg pain (sciatica) that may be worse than back pain—often one-sided, shooting from the buttock to the calf or foot.
Numbness, tingling, or burning along the nerve path (L4, L5, or S1 dermatomes).
Weakness in the leg or foot (difficulty lifting the foot, pushing off, or climbing stairs) when the nerve is significantly compressed.
Lower back pain or stiffness, which may accompany but is often less disabling than leg symptoms.
Pain that increases with prolonged sitting, forward bending, lifting, cough, or Valsalva maneuver.
Cauda equina warning signs—saddle anesthesia, new bladder/bowel dysfunction, or bilateral leg weakness—require emergency evaluation.

What is Lumbar Discectomy (Microdiscectomy)?
Lumbar disc herniation occurs when the soft nucleus pulposus protrudes through a tear in the annulus fibrosus and compresses nearby nerve roots in the lower back, producing sciatica and sometimes weakness.
Conditions Related to Lumbar Discectomy (Microdiscectomy)
Contained disc protrusion or extrusion at L4–L5 or L5–S1 (most common levels).
Sciatica from nerve-root compression without cauda equina syndrome.
Large central disc herniation (urgent evaluation if cauda equina symptoms).
Recurrent disc herniation after prior discectomy (~5–15%).
Lumbar spondylosis and facet arthropathy that coexist with herniation.
Causes of Lumbar Discectomy (Microdiscectomy)
Disc Degeneration & Annular Tears: Age-related disc dehydration and micro-tears allow nucleus material to herniate under load.
Heavy lifting, twisting, or sudden loading with poor mechanics.
Prolonged sitting and sedentary work (common in desk-based IT jobs).
Overweight and metabolic factors (obesity, diabetes) that affect disc health and healing.
Smoking and nicotine exposure, linked to impaired disc nutrition and slower recovery.
Prior disc injury, repetitive flexion-extension sports, or occupational driving/vibration.
Genetic predisposition to early disc degeneration in some families.
What is Lumbar Discectomy (Microdiscectomy)?
Lumbar microdiscectomy removes the fragment of disc pressing on the nerve while leaving most of the disc in place. It is the standard surgical treatment for persistent sciatica from herniation when conservative care has not provided adequate relief.
Targets the herniated fragment causing nerve compression—not the entire disc.
Performed open, through a tubular retractor, or endoscopically depending on anatomy and surgeon expertise.
Aims for rapid leg pain relief; back pain may improve more gradually.
Does not require fusion for typical isolated herniation without instability.
Recurrent herniation at the same level occurs in roughly 5–15% of patients over time.
Do You Really Need Surgery?
Not every disc herniation needs surgery. Many improve with time, activity modification, physiotherapy, and medications. Surgery is considered when leg pain is severe, function is limited, or neurologic deficits progress despite an adequate trial of non-operative care.
Persistent sciatica for 6–12 weeks despite structured conservative treatment.
Progressive leg weakness or foot drop.
Intolerable pain limiting work, sleep, or daily activities.
Correlating MRI showing nerve-root compression matching the clinical syndrome.
Cauda equina syndrome—immediate surgery regardless of duration.
What Happens if You Delay Treatment?
Many herniations settle with conservative care, but prolonged nerve compression can prolong pain and, in rare cases, allow weakness to persist. Cauda equina symptoms should never be delayed.
Ongoing sciatica and reduced quality of life while awaiting improvement.
Persistent numbness or weakness that may recover more slowly the longer it lasts.
Work disability and deconditioning from avoiding activity due to pain.
Rare progression to cauda equina syndrome if a large central herniation expands.
When Should You See a Spine Surgeon? (Warning Signs)
Seek urgent spine evaluation if you develop saddle anesthesia, difficulty urinating, fecal incontinence, rapidly worsening bilateral leg weakness, or sudden severe leg paralysis.
New or worsening foot drop or major leg weakness.
Types of Procedures for Lumbar Discectomy (Microdiscectomy)
Discectomy techniques differ by incision size, visualization (microscope vs endoscope), and how muscle is retracted—but all aim to remove the compressive disc fragment and free the nerve root.
Open Microdiscectomy
A small midline or paramedian incision with muscle retraction and operating microscope/loupes to remove the herniated fragment under direct vision. Reliable for most disc sizes and locations.
Minimally Invasive Tubular Microdiscectomy
Serial dilators and a tubular retractor spare muscle; the microscope provides magnification for fragment removal. Often shorter recovery and less postoperative back pain in selected cases.
Endoscopic Lumbar Discectomy
Camera-guided surgery through a small portal (transforaminal or interlaminar). Attractive for suitable herniations; may carry higher facility costs in premium centers.
Laminotomy / Foraminotomy with Discectomy
Targeted bone removal at the lamina or foramen enlarges the nerve tunnel before disc removal—useful when stenosis coexists with herniation.

Expert Guidance, Every Step of the Way
Our dedicated care coordinators are here to answer your questions and guide you through every stage of your treatment.
Early mobilization and pain control while inpatient.
Day 0–1: Transfer from bed with log-roll technique; begin standing/walking with assistance.
Pain team adjusts analgesia to allow movement while minimizing sedation.
Physical therapy teaches spine precautions and safe stair negotiation before discharge.
Gradual return to activity with surgeon-guided restrictions.
Weeks 1–2: Short walks, incision care, avoid heavy lifting (>5–10 kg) and twisting.
Weeks 2–6: Increase walking; light desk work may resume; continue core stabilization exercises.
Weeks 6–12+: Progressive return to heavier work/sports as strength and fusion (if any) allow.
8If leg pain persists, what is the plan for investigation and rehabilitation?
9Is my surgery covered by insurance and what implants/hospital tier affect cost?
10Who handles emergencies or questions after hours during the first month?
What is the success rate?
Approximately 85–95% of appropriately selected patients experience meaningful leg pain relief; back pain may respond more variably.
Can the disc herniate again?
Recurrent herniation at the same level occurs in about 5–15% of patients over time.
How soon can I return to work?
Desk work may resume in 2–6 weeks; heavy manual labor often requires 6–12 weeks or longer depending on recovery.
Do I need a fusion with my discectomy?
Typical isolated herniations without instability are treated with discectomy alone. Fusion is added when spondylolisthesis or instability is present.
What does the SPORT trial show?
The Spine Patient Outcomes Research Trial (SPORT), published in NEJM, found that surgery for lumbar disc herniation provided faster leg pain relief than continued non-operative care in selected patients with persistent symptoms.
What are activity restrictions after surgery?
Surgeons usually limit heavy lifting, twisting, and prolonged bending for several weeks while tissues heal—exact rules vary by technique and individual healing.
Is endoscopic discectomy better than open?
Outcomes depend on surgeon experience and herniation anatomy. Endoscopic and tubular approaches may reduce muscle pain in suitable cases; open microdiscectomy remains the widely proven standard.
What is the typical hospital stay in India?
Many centers discharge the same day or after 1–2 days for uncomplicated microdiscectomy.
What does surgery cost in India?
Costs vary widely: roughly ₹30,000–₹80,000 in many government setups, ₹1.2–2.2 lakh in mid-tier private hospitals, and ₹2.2–4 lakh+ in premium corporate centers; endoscopic options may cost more.
When should I choose surgery over injections?
Injections may bridge flares, but persistent sciatica with correlating herniation after a structured conservative trial is when microdiscectomy is typically discussed.
What warning signs need emergency care?
Saddle anesthesia, bladder/bowel dysfunction, rapidly worsening weakness, or bilateral leg paralysis require immediate emergency evaluation.
