MIS TLIF
Minimally Invasive Transforaminal Lumbar Interbody Fusion — a guide for patients and families
A guide by Dr. Amit Chanduka, Neurosurgeon & Spine Surgeon, explaining MIS TLIF, who it suits, and what to expect before, during, and after surgery.
Book ConsultationWhat Is MIS TLIF?
MIS TLIF stands for Minimally Invasive Transforaminal Lumbar Interbody Fusion. It achieves exactly the same goal as traditional (open) TLIF — removing a damaged disc and fusing two vertebrae into one stable segment — but reaches the spine through a small incision instead of a single long midline cut.
Dr. Chanduka uses a tubular retractor system that gently spreads the muscle fibres apart rather than cutting or peeling them off the bone. This means the same surgery is performed with far less disruption to the surrounding muscle, which is the main reason recovery tends to be quicker and less painful than with the open approach.
Think of it as reaching the same destination through a narrow, dilated tunnel instead of a wide-open path — the surgery itself is just as thorough, but the route there is gentler on the body.
When Is MIS TLIF Recommended?
MIS TLIF is Dr. Chanduka's preferred approach for most straightforward single or two-level fusions, where the anatomy doesn't demand the wider access of open surgery. It is typically considered for:
- Single or two-level disc disease causing nerve compression and leg pain
- Spondylolisthesis (a slipped vertebra) where the instability is confined to one level
- Spinal stenosis with instability, where decompression and fusion are both needed
- Patients who are otherwise good surgical candidates and want the fastest reasonable recovery
- Cases with minimal deformity, prior spine surgery, or complex anatomy at the affected level are usually better suited to open surgery instead
What Happens During the Procedure
- 1You lie face-down on the operating table.
- 2Using X-ray guidance, Dr. Chanduka places a small tubular retractor through a 2–2.5-centimetre incision, dilating the muscle rather than cutting it.
- 3Working through the tube, the damaged disc is removed and the compressed nerve is decompressed.
- 4A spacer (cage) packed with bone graft is placed in the disc space to restore height and support.
- 5Screws and rods are placed through small separate incisions, guided by X-ray, to stabilise the segment.
- 6The tube is removed at the end, leaving only one or two small incisions rather than one long one.
Preparing for Your Surgery
- Blood tests, and an ECG or chest X-ray if advised, to confirm you are fit for anaesthesia
- Some regular medicines (especially blood thinners) may need to be paused — you will get exact instructions
- You will be asked to stop eating and drinking for a set number of hours before surgery
- Arrange for a family member to be with you, and for help at home for the first 1–2 weeks after you return
Recovery: What to Expect
Because the muscle is dilated rather than cut, recovery is generally faster and less painful than open surgery.
Many patients are walking with support within hours of surgery. Pain is typically mild and well controlled with medication. Hospital stay is often just 2–3 days.
Rest at home with regular short walks. Avoid bending, twisting, or lifting anything heavier than about 2–3 kg.
Walking distance increases steadily. Light household and desk-based activity often resumes during this window.
Back strengthening exercises typically begin to rebuild core and back strength.
Bone fusion continues to strengthen, checked with follow-up X-rays. Full activity is guided by how solid the fusion looks and how you feel.
Risks and When to Call Us
MIS TLIF carries the same general risks as any spine fusion — infection, bleeding, nerve irritation, or the fusion taking longer than expected to solidify — but typically with less blood loss and less post-operative muscle pain than the open approach.
Please contact the clinic promptly if, after surgery, you notice:
- Fever, or redness/discharge from any incision
- New or worsening numbness, weakness, or pain in the legs
- Difficulty controlling your bladder or bowel
- Severe pain not relieved by your prescribed medication
