Minimally Invasive Spinal Fusion Surgery
Overview
Minimally invasive spinal fusion is a modern surgical technique that stabilizes the spine while minimizing disruption to surrounding tissues. Using smaller incisions and advanced instrumentation, this approach reduces muscle damage, blood loss, and recovery time compared to traditional open fusion surgery. It is commonly used to treat spinal instability, degenerative disc disease, and other chronic spine conditions.
Indications
Minimally invasive spinal fusion may be appropriate for patients with:
- Degenerative disc disease or disc collapse
- Spondylolisthesis (slipped vertebra)
- Chronic back pain related to spinal instability
- Spinal deformities (e.g., scoliosis)
- Failed previous spine surgeries requiring stabilization
Procedure
The surgery is typically performed under general anesthesia using one of several techniques, such as MIS-TLIF or XLIF:
- Small incisions are made in the back or side of the spine
- Tubular retractors and microscopes allow access to the spine with minimal muscle disruption
- Damaged disc material is removed, and bone grafts or cages are inserted between vertebrae
- Screws and rods are placed through percutaneous (through-the-skin) methods to stabilize the spine
- Incisions are closed with minimal scarring
Risks & Considerations
As with all spinal fusion surgeries, there are potential risks, including:
- Infection or bleeding
- Nerve injury or spinal fluid leak
- Hardware malfunction or nonunion (failure to fuse)
- Continued pain or need for revision surgery
- Limited motion at the fused segment
Recovery & Outcomes
- Shorter hospital stays—many patients go home within 24–48 hours
- Less postoperative pain and quicker return to daily activities
- Light activity can usually resume in 2–4 weeks
- Full fusion and recovery may take 3–6 months
- High success rates for pain reduction and improved spinal stability
