Overview
Transforaminal Lumbar Interbody Fusion (TLIF) replaces a damaged disc and restores structural integrity to the vertebrae of the lumbar spine. Using a minimally invasive posterior approach with lateral entry, the surgeon pushes away muscles and ligaments without cutting them — reducing blood loss, pain and healing times. Tube-like instruments reach the targeted vertebrae to extract disc material, and the damaged disc is replaced with a bone graft, reinforced by screws, plates and rods during healing.
The Procedure
- 1Minimally invasive posterior approach with lateral entry
- 2Muscles and ligaments pushed aside rather than cut
- 3Disc material extracted via tube-like instruments
- 4Foraminal openings expanded for nerve decompression
- 5Damaged disc replaced with bone graft (pelvis, donor or synthetic)
- 6Fusion hardware (screws, plates, rods) reinforces the graft
Benefits
- Smaller incisions
- Reduced pain and external scarring
- Hospital stays of 1–2 days for most patients
- Minimised surrounding tissue damage
- Shortened recovery timeframe
When it May Not Be Suitable
- Infections near the surgical site
- Prior failed fusions
- Severe vertebral instability
Recovery Timeline
Hospital stay
Typically 1–2 days. You'll be helped to stand and walk soon after surgery.
First 2 weeks
Rest with short, frequent walks. Avoid bending, lifting and twisting. A brace may be advised.
6–12 weeks
Progressive return to light activities and work; physiotherapy begins as the fusion settles.
3–6 months
Bony fusion matures; most patients return to full activity with a strong, stable spine.
Minimally Invasive vs Open Surgery
| Factor | Minimally Invasive | Open Surgery |
|---|---|---|
| Incision size | Small (often 8mm–2cm) | Large |
| Muscle damage | Minimal — muscles separated | More — muscles cut |
| Blood loss | Low | Higher |
| Post-op pain | Less | More |
| Hospital stay | Short (day-care to 1–2 days) | Longer |
| Scarring | Minimal | More visible |
| Return to activity | Faster | Slower |
| Infection risk | Lower | Higher |
