What each procedure actually does
Non-surgical decompression uses a computer-controlled table to apply and release a precise distraction force along the axis of the spine. Each cycle creates negative pressure inside the targeted disc, which draws retracted fluid, oxygen and nutrients back in and encourages bulging material to move away from the nerve root. Sessions run 25 to 30 minutes, you stay clothed, and you drive yourself home.
Spinal fusion removes the disc or decompresses the canal surgically, packs bone graft into the space, and fixes the vertebrae together with screws, rods or cages until they knit into one bone. The pain generator is not repaired — it is immobilised. That is the correct answer when movement itself is the problem, and the wrong answer when the disc could still recover.
Recovery time compared
Decompression has no recovery period in the surgical sense. Patients work through their course, typically three sessions a week for six to eight weeks, and most notice referred pain retreating towards the spine within four to six sessions.
Fusion involves two to five days in hospital, six to twelve weeks of restricted bending, lifting and twisting, and six to twelve months before the bone graft is considered solid. Return to desk work is commonly four to six weeks; physical work is often three to six months.
Risk profile of fusion you should discuss with your surgeon
- Adjacent-segment disease — the levels above and below carry the load the fused segment no longer shares
- Permanent loss of movement at the fused level
- Failed fusion (non-union) requiring revision surgery
- Hardware irritation, infection and anaesthetic risk
- Persistent pain despite technically successful surgery
Who is eligible for non-surgical decompression
Decompression suits contained disc bulges and most herniations, discogenic back and neck pain, lumbar or cervical nerve-root pain, degenerative disc disease and mild to moderate stenosis. It is also used after surgery to rehabilitate the segments around a fusion.
It is not appropriate with spinal instability, fracture, tumour, active infection, severe osteoporosis, pregnancy, abdominal aortic aneurysm or existing lumbar hardware at the treated level. In those situations a surgical opinion is the right path, and we will tell you so at assessment.
When fusion is genuinely the right call
Cauda equina syndrome is a surgical emergency — bladder or bowel change, or saddle numbness, means an emergency department today, not a clinic appointment. Progressive motor weakness such as a dropping foot, high-grade spondylolisthesis, unstable fracture, significant deformity and structurally proven instability that has failed a complete conservative course are the other clear indications.
Outside those, the sequence that protects you is straightforward: exhaust reversible, non-destructive care first, then operate with a clear structural target if it fails. Surgery remains available after decompression. Movement at a fused segment does not return.
Cost, in Delhi terms
A full decompression and rehabilitation course at Back2Health costs a small fraction of instrumented fusion in Delhi NCR once implants, hospital stay, anaesthesia and physiotherapy are counted, and it carries no lost-income period of weeks to months. Call the clinic for transparent per-session and package pricing after your MRI is reviewed.
