Endoscopic
Lumbar Fusion
Lumbar spinal fusion performed entirely through endoscopic access — combining decompression and stabilisation with the smallest possible incisions.
Endoscopic Lumbar Fusion
The stability of spinal fusion delivered through the least invasive approach currently available.
Same fusion result as MIS-TLIF — with less blood loss, less muscle damage, and faster early recovery. Fusion consolidation still takes three to six months regardless of approach.
What Is It?
Endoscopic lumbar fusion combines the nerve decompression of endoscopic spine surgery with the vertebral stabilisation of spinal fusion — performed through portals of under one centimetre. The disc is removed, the disc space is prepared, an interbody cage and bone graft are inserted, and pedicle screws are placed percutaneously under navigation guidance. Also called Endo-TLIF (Endoscopic Transforaminal Lumbar Interbody Fusion).
Before Surgery
MRI, CT, and standing X-rays reviewed for pre-operative planning. Navigation mapping performed before surgery. Medical clearance, blood work required. Smoking cessation essential — it directly impairs fusion rates regardless of surgical approach.
During Surgery
General anaesthesia. Endoscopic portals under one centimetre. Disc removed and disc space prepared endoscopically. Interbody cage placed through the endoscopic access. Pedicle screws inserted percutaneously under Medtronic navigation guidance. Typically 90–150 minutes per level.
After Surgery
Hospital stay: two to three days — shorter than open fusion. Significantly less post-operative back pain due to minimal muscle disruption. Walking with assistance the same day or the day after surgery.
Recovery
Desk work: four to eight weeks. The fusion itself — bone growing across the treated segment — takes three to six months regardless of surgical approach. Regular imaging at three and six months confirms consolidation. Return to physical activity guided by fusion progress.
Dr. Viswanath's Approach
Endoscopic lumbar fusion is a technically demanding procedure. It is offered for appropriate single or two-level cases where the patient is a suitable candidate and would benefit meaningfully from the reduced approach morbidity. Medtronic navigation is used for all percutaneous screw placements. Complex multi-level or revision cases are managed with conventional MIS or open approaches.
