What is Spinal Fusion?
Spinal fusion is a surgical procedure that permanently joins (fuses) two or more vertebrae together, eliminating motion at that segment. It is performed when the source of pain is an unstable or degenerated spinal segment, and when conservative management has failed to provide adequate relief.
Modern spinal fusion uses interbody cages (packed with bone graft or bone substitutes) placed in the disc space, combined with pedicle screws and connecting rods for immediate rigid fixation. Over 3–12 months, bone grows through the cage creating a solid fusion. Dr. Chugh performs all fusions using minimally invasive (MIS) techniques whenever appropriate, dramatically reducing recovery time.
Fusion Techniques
Indications for Spinal Fusion
- Spondylolisthesis (vertebral slippage) with instability
- Spinal stenosis combined with instability
- Degenerative disc disease causing intractable back and leg pain
- Recurrent disc herniation at the same level
- Spinal fracture instability
- After decompression when structural instability is created
Recovery
Days 1–3
Walking same day or day 1. Discharged day 3–4 for MIS fusion (day 5–7 for open multi-level).
Weeks 2–6
Walking programme. Lumbar brace. Light activities. Work from home possible at week 4–6.
3 Months
Physiotherapy commenced. Early fusion seen on CT/X-ray. Return to active life.
6–12 Months
Solid fusion confirmed. Full return to activities. Ongoing core maintenance exercises.
