MIS-TLIF (Minimally Invasive TLIF)

What the procedure is

MIS-TLIF achieves the same fusion goal as a conventional TLIF, using a smaller, muscle-sparing surgical corridor and image-guided instrumentation to place the interbody cage and pedicle screws.

Why it is performed

It provides the stabilising benefit of fusion while reducing muscle disruption compared with an open approach, in appropriately selected patients.

Who may benefit

• Patients who are candidates for single or two-level fusion and are suitable for a minimally invasive approach
• Patients concerned about muscle-related recovery time after open fusion

When it may not be appropriate

• Complex multi-level deformity correction, which is usually better served by an open approach
• Cases with distorted anatomy from prior surgery that limits minimally invasive access

Alternatives

• Open TLIF
• Decompression alone where instability is not present

How it is performed

Working through small tubular incisions on one or both sides, the surgeon removes the disc, places an interbody cage, and inserts percutaneous pedicle screws under image guidance, minimising disruption to the surrounding paraspinal muscles.

Anaesthesia: General anaesthesia  ·  Typical duration: Approximately 2–3.5 hours per level  ·  Typical hospital stay: 2–4 nights

Recovery

Many patients report less early post-operative pain than with open fusion. A typical course: days 1–3, walking with support and pain managed with medication, often with a light brace; week 1–2, home-based recovery with short walks, wound check around day 14; weeks 3–6, gradual increase in activity and light desk work for many patients, still avoiding bending, twisting or lifting; weeks 6–12, most patients resume normal daily activity and non-strenuous work, with X-rays tracking fusion progress; fusion itself continues maturing for 6–12 months, so activity restrictions ease gradually rather than all at once.

Physiotherapy

Early mobilisation followed by a progressive core-strengthening and conditioning programme.

Risks and complications

• Non-union
• Screw malposition
• Nerve injury
• Infection
• Conversion to an open approach if needed intra-operatively

Expected follow-up

Clinical and X-ray review over the following year to confirm fusion.
