MIS TLIF (Minimally Invasive Transforaminal Lumbar Interbody Fusion) is an advanced minimally invasive spine surgery performed to treat spinal instability, slipped vertebrae (Spondylolisthesis), recurrent disc problems and certain degenerative conditions affecting the lumbar spine.
The goal of the surgery is to:
Decompress the affected nerves
Restore spinal stability
Correct abnormal spinal alignment
Relieve pain
Promote fusion between two vertebrae
The procedure is performed through small incisions using specialized tubular retractors, microscopic visualization and pedicle screw fixation systems. A cage filled with bone graft is inserted into the disc space to facilitate fusion.
This is a minimally invasive fusion surgery that combines nerve decompression with spinal stabilization.
Why Is This Surgery Performed?
This surgery may be recommended for:
Spondylolisthesis
Lumbar Instability
Recurrent Slip Disc
Degenerative Disc Disease
Foraminal Stenosis
Lumbar Canal Stenosis with Instability
Mechanical Low Back Pain due to instability
Revision Spine Surgery
Common symptoms that may lead to surgery include:
Chronic low back pain
Sciatica
Leg pain
Numbness
Tingling sensations
Weakness in the legs
Difficulty walking
Back pain aggravated by standing or movement
Who Is A Suitable Candidate?
You may be a suitable candidate if:
✓ Symptoms persist despite medications and physiotherapy
✓ Conservative treatment has failed
✓ MRI and dynamic X-rays demonstrate instability
✓ Recurrent disc herniation is present
✓ Spondylolisthesis is causing symptoms
✓ Leg pain and back pain significantly affect daily activities
✓ Quality of life is compromised
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
Small skin incisions are made over the affected spinal level.
Step 3
Pedicle screws are inserted using minimally invasive techniques under image guidance.
Step 4
A tubular retractor is used to access the affected side of the spine while minimizing muscle injury.
Step 5
The compressed nerves are carefully decompressed using microscopic techniques.
Step 6
The damaged disc is removed and the disc space is prepared.
Step 7
A cage filled with bone graft is inserted between the vertebrae to restore disc height and promote fusion.
Step 8
Rods are connected to the screws to stabilize the spine.
Step 9
The wounds are closed and sterile dressings are applied.
Most procedures are completed within 2–4 hours depending on complexity and the number of levels involved.
What Are The Advantages?
Potential benefits include:
Smaller incisions
Less blood loss
Reduced muscle damage
Less postoperative pain
Faster recovery
Earlier mobilization
Improved spinal stability
Reduced hospital stay
Faster return to daily activities
High fusion rates
Improved quality of life
Compared to traditional open fusion surgery, MIS TLIF significantly reduces soft tissue disruption while achieving the same surgical objectives.
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 TLIF is performed using high-definition operating microscopes, specialised minimally invasive tubular retractors, modern pedicle screw systems and advanced imaging guidance. These technologies allow accurate decompression, implant placement and fusion while minimizing disruption to surrounding 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
Implant-related complications
Cage migration
Screw malposition
Non-union (failure of fusion)
Persistent symptoms
Adjacent segment degeneration
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
Dynamic X-rays
CT scan (if required)
Blood investigations
Medical fitness assessment
Medication review
Anaesthesia assessment
Patients should inform their doctor regarding:
Blood thinning medications
Diabetes
Heart disease
Osteoporosis
Previous surgeries
Allergies
Smoking history
Smoking cessation is strongly encouraged as it improves fusion rates and healing.
What Happens During Hospital Stay?
Day of Surgery
Hospital admission
Surgery
Recovery room observation
Pain management
Assisted mobilization
First 24–48 Hours
Walking under supervision
Physiotherapy guidance
Wound care
Gradual increase in activities
Discharge
Most patients are discharged within:
2–4 days
depending on recovery and overall medical condition.
Recovery After Surgery
Week 1
Expected symptoms:
Mild wound discomfort
Improvement in leg symptoms
Walking encouraged
Light activities permitted
Weeks 2–6
Progressive walking program
Return to routine activities
Physiotherapy if advised
Follow-up consultation
6 Weeks–3 Months
Bone fusion process continues
Progressive strengthening exercises
Significant improvement in pain and function
Long-Term Recovery
Fusion typically continues over several months. Most patients experience substantial improvement in pain, walking ability and quality of life.
Maintaining spinal fitness, healthy body weight and regular exercise contributes to long-term success.
Frequently Asked Questions
1. Why do I need this surgery?
Because your spine has become unstable or a nerve is being compressed in a way that requires both decompression and stabilization.
2. Are there alternatives to surgery?
Many patients improve with medications, physiotherapy and injections. Surgery is usually considered when symptoms persist despite adequate conservative treatment.
3. Will I have a large scar?
No. MIS TLIF is performed through small incisions using minimally invasive techniques.
4. How long will I stay in hospital?
Most patients remain in hospital for approximately 2–4 days.
5. When can I start walking after surgery?
Most patients are encouraged to walk within a few hours after surgery under supervision.
6. When can I start outdoor walking?
Indoor walking begins immediately after surgery. Outdoor walking usually starts after approximately 1 week.
7. When can I travel after surgery?
Short local travel is generally possible after about 2 weeks. Long-distance travel is usually recommended after 6–8 weeks.
8. When can I return to work?
Typical timelines are:
Work From Home (WFH): Approximately 2–3 weeks
Office-Based Work: Approximately 4–6 weeks
Light Physical Work: Approximately 6–8 weeks
Heavy Manual Labour: Approximately 3–6 months
9. When can I drive, exercise, dance or resume sports?
Driving is usually permitted after approximately 4–6 weeks.
Sports, gym workouts, dancing and high-impact activities are generally resumed after 3–6 months depending on fusion progress and your surgeon’s advice.
10. What is the success rate of MIS TLIF?
When performed for appropriate indications, MIS TLIF has excellent success rates for relieving leg pain, improving spinal stability and enhancing quality of life.
Most patients experience substantial improvement in pain and function, particularly when surgery is performed before severe nerve damage develops.
11. Will the vertebrae permanently fuse together?
Yes. The objective of TLIF surgery is to achieve a solid fusion between the involved vertebrae, creating long-term stability and reducing painful abnormal motion.
Myth vs Fact
Myth:
Fusion surgery means I will not be able to bend or move normally.
Fact:
Most patients return to normal daily activities after recovery. Fusion occurs only at the affected spinal level, while the remaining spine continues to move normally.
Myth:
Spinal implants need to be removed later.
Fact:
In most cases, implants remain permanently and do not require removal unless a specific problem develops.
When Should I Contact My Surgeon After Surgery?
Contact your surgeon if you experience:
Fever
Increasing wound discharge
Severe back or leg pain
Progressive weakness
Difficulty passing urine
New numbness
Persistent headache
Significant wound swelling
