MIS Lumbar Fusion
Spinal fusion through small incisions with significantly less disruption to surrounding muscle and tissue.
MIS Lumbar Fusion
All the stability of spinal fusion — through smaller incisions, with less tissue damage and faster recovery.
Same outcome as open fusion with less blood loss and shorter hospital stay. The fusion itself still takes three to six months to consolidate.
What Is It?
Achieves the same goal as open spinal fusion — stabilising an unstable segment — but through much smaller incisions using specialised retractors and navigation guidance. Less muscle damage means less post-operative pain and faster return to activity.
Before Surgery
MRI, CT, and standing X-rays reviewed. Medical clearance and blood work. Navigation planning performed pre-operatively. Smoking cessation strongly advised — it directly impairs bone fusion.
During Surgery
General anaesthesia. Small incisions, specialised tubular retractors, navigation-guided screw placement. Bone graft placed to promote fusion. Typically 90–150 minutes depending on levels.
After Surgery
Hospital stay: two to four days — shorter than open fusion. Less post-operative pain. Walking with assistance the day after surgery. Brace may be used for six to eight weeks.
Recovery
Desk work: four to eight weeks. Bone fusion takes three to six months regardless of approach. Imaging confirms consolidation at three and six months.
Dr. Viswanath's Approach
MIS approach used where anatomy is suitable and the patient is a good candidate. Medtronic navigation used for all screw placements to ensure accuracy through limited exposure.
