MIS Decompression (Tubular) is a minimally invasive spine surgery performed to relieve pressure on the spinal nerves caused by narrowing of the spinal canal (Lumbar Canal Stenosis) or other degenerative conditions affecting the spine.
The goal of the surgery is to create more space for the nerves by removing the structures causing compression while preserving as much of the normal spinal anatomy as possible.
The procedure is performed through a small incision using specialized tubular retractors and an operating microscope. By gently separating rather than cutting the muscles, the surgery minimizes tissue damage and promotes faster recovery.
This is a minimally invasive microscopic spine surgery commonly performed for patients suffering from nerve compression, leg pain and walking difficulty due to spinal stenosis.
Why Is This Surgery Performed?
This surgery may be recommended for:
Lumbar Canal Stenosis
Lateral Recess Stenosis
Foraminal Stenosis
Degenerative Facet Joint Hypertrophy
Ligamentum Flavum Hypertrophy
Nerve Compression Syndromes
Common symptoms that may lead to surgery include:
Pain in the legs while walking
Neurogenic Claudication
Leg numbness
Tingling sensations
Weakness in the legs
Difficulty standing for long periods
Walking intolerance
Relief on sitting or bending forward
Who Is A Suitable Candidate?
You may be a suitable candidate if:
✓ Symptoms persist despite medications and physiotherapy
✓ Walking distance is progressively reducing
✓ MRI confirms nerve compression due to spinal stenosis
✓ Leg symptoms are affecting daily activities
✓ Conservative treatment has failed
✓ Quality of life is significantly affected
✓ Progressive neurological weakness develops
How Is The Surgery Performed?
Step 1
The procedure is performed under general anesthesia. The patient is positioned face down on a specialized operating table.
Step 2
A small skin incision, typically around 18–25 mm, is made over the affected spinal level.
Step 3
Specialized tubular retractors are inserted through the muscles, creating a muscle-sparing pathway to the spine.
Step 4
Using an operating microscope, the compressed nerves are identified.
Step 5
The structures causing nerve compression, such as thickened ligaments, enlarged facet joints or bony overgrowths, are carefully removed.
Step 6
Once the nerves are adequately decompressed, the instruments are removed and the incision is closed.
Most procedures are completed within 60–120 minutes depending on the number of levels involved.
What Are The Advantages?
Potential benefits include:
Small incision
Less blood loss
Reduced muscle injury
Less postoperative pain
Faster recovery
Shorter hospital stay
Earlier mobilization
Preservation of spinal stability
Reduced need for pain medications
Improved walking capacity
Better quality of life
Compared to traditional open laminectomy, tubular decompression preserves more normal anatomy and reduces soft tissue disruption.
What Are The Risks?
Every surgical procedure carries certain theoretical risks and potential complications. However, every effort is made to minimise these risks through meticulous surgical planning, advanced technology and comprehensive patient optimisation.
At Bombay Spine Clinic™, MIS Decompression is performed using a high-definition operating microscope, specialised minimally invasive tubular retractors and modern microsurgical instruments. These technologies allow precise decompression of the affected nerves through a small incision while minimising disruption to surrounding muscles and tissues.
In addition, every patient undergoes a thorough pre-operative assessment. Depending on individual health requirements, this may involve evaluation and optimisation by physicians, cardiologists, anaesthetists and other medical specialists. This multidisciplinary approach helps improve surgical safety, recovery and overall outcomes.
Potential risks that are discussed with patients include:
Infection
Bleeding
Dural tear (CSF leak)
Nerve injury
Persistent numbness
Persistent weakness
Incomplete symptom relief
Recurrent symptoms
Rare need for revision surgery
Fortunately, the incidence of significant complications is low when surgery is performed for appropriate indications, following careful patient selection, optimisation and modern minimally invasive surgical principles.
Preparing For Surgery
Before surgery:
Clinical evaluation
MRI review
Blood investigations
Medical fitness assessment
Medication review
Anaesthesia assessment
Patients should inform their doctor regarding:
Blood thinning medications
Diabetes
Heart disease
Previous surgeries
Allergies
Smoking history
Smoking cessation is strongly encouraged as it improves healing and recovery.
What Happens During Hospital Stay?
Day of Surgery
Hospital admission
Surgery
Recovery room observation
Early mobilization under supervision
First 24 Hours
Pain management
Walking with assistance
Physiotherapy instructions
Wound care guidance
Discharge
Most patients are discharged within:
24–72 hours
Selected patients may even be discharged earlier depending on recovery.
Recovery After Surgery
Week 1
Expected symptoms:
Mild wound discomfort
Improvement in leg symptoms
Walking encouraged
Light daily activities permitted
Weeks 2–6
Progressive increase in walking distance
Gradual return to daily activities
Physiotherapy if advised
Follow-up consultation
6 Weeks–3 Months
Progressive strengthening exercises
Significant improvement in walking capacity
Improved function and independence
Long-Term Recovery
Most patients experience substantial improvement in walking ability, leg pain and overall quality of life. Maintaining spinal fitness and regular exercise helps sustain long-term benefits.
Frequently Asked Questions
1. Why do I need this surgery?
Because narrowing of the spinal canal is compressing your nerves and causing symptoms such as leg pain, numbness or difficulty walking.
2. Are there alternatives to surgery?
Yes. Many patients improve with medications, physiotherapy, activity modification and epidural injections. Surgery is considered when symptoms persist despite adequate conservative treatment.
3. Will I have a large scar?
No. MIS Tubular Decompression is performed through a small incision, typically around 18–25 mm.
4. How long will I stay in hospital?
Most patients stay in hospital for 1–3 days depending on the extent of surgery and recovery.
5. When can I start walking after surgery?
Most patients are encouraged to start walking within a few hours after surgery under supervision.
6. When can I start outdoor walking?
Indoor walking is encouraged immediately after surgery. Outdoor walking can usually begin after approximately 1 week.
7. When can I travel after surgery?
Short local travel is usually possible after about 2 weeks. Longer journeys and air travel are generally recommended after 6–8 weeks.
8. When can I return to work?
Typical timelines are:
Work From Home (WFH): Approximately 2 weeks
Office-Based Work: Approximately 3–4 weeks
Light Physical Work: Approximately 4–6 weeks
Heavy Manual Labour: Approximately 8–12 weeks
9. When can I drive, exercise, dance or resume sports?
Driving is usually permitted after approximately 3–4 weeks. Sports, gym workouts, dancing and high-impact activities are generally resumed after 10–12 weeks depending on recovery.
10. What is the success rate of MIS Decompression?
When performed for appropriate indications, MIS Decompression has a high success rate in relieving nerve compression symptoms and improving walking ability. Most patients experience significant improvement in leg pain and quality of life.
11. Can the symptoms return?
While most patients experience long-term relief, degenerative changes in the spine may continue with aging. Maintaining a healthy lifestyle and regular exercise can help reduce recurrence of symptoms.
Many patients with spinal stenosis can be effectively treated with decompression surgery alone without the need for spinal fusion.
Myth:
Walking should be avoided after spine surgery.
Fact:
Early walking is encouraged and forms an important part of the recovery process.
When Should I Contact My Surgeon After Surgery?

Progressive weakness
Severe leg pain
Difficulty passing urine
New numbness
