Neither is simply better, the right choice depends on what’s being treated and how complex it is. Minimally invasive surgery uses small incisions and causes less muscle damage, so recovery is faster and pain is lower. Open surgery gives wider access, which matters for complex deformities, multilevel disease and revisions. For straightforward problems the minimally invasive route usually wins on recovery. For complicated ones, open surgery is often the safer call.
According to Dr. Gurneet Singh Sawhney, a leading spine surgeon in Mumbai, the smaller incision was never the goal, the right operation for the spine in front of me is. A keyhole approach is excellent for the cases that fit it, but forcing it onto a complex deformity helps no one.
Unsure which spine procedure your case needs?
What Makes Minimally Invasive Surgery Appealing?
Minimally invasive techniques reach the spine through small openings that spread muscle rather than cut it.
Muscle: tubular retractors dilate the tissue instead of stripping it off the bone, which is the main reason recovery runs quicker
Blood: a smaller exposure means less bleeding during the operation and a lower chance of needing a transfusion
Recovery: many patients walk within a day and head home in one to three, far sooner than a big open wound allows
Infection: a smaller wound carries a lower infection risk, and that edge matters most in older or higher-risk patients
And for a single disc or a short decompression, the trade is almost all upside. That’s where spine surgery through a keyhole approach really earns its place.
When Does Radiation Make More Sense?
Open surgery stays the standard when the spine needs wide access, correction, or repair across several levels.
Deformity: correcting scoliosis or major curves needs the direct visualisation and reach that only an open exposure provides
Revision: scarred tissue from a previous operation is often safer to navigate through a full open approach
Multilevel: disease spread across several segments can be too much ground for a keyhole technique to cover well
Pain: when stubborn nerve pain isn’t structural, options like spinal cord stimulation can matter more than the size of any incision
So bigger isn’t worse, it’s sometimes exactly what the spine needs. This explainer on minimally invasive spine surgery shows where the keyhole route fits and where it doesn’t.
Why Choose Dr. Gurneet Singh Sawhney?
Dr. Gurneet Singh Sawhney trained in minimally invasive spine surgery through cadaveric and endoscopic fellowships, and has more than 18 years across both keyhole and open techniques. That range means the approach gets matched to the problem, not to a preference.
Patients with a simple herniated disc often go home walking the next day, while complex cases get the full exposure they actually need. The incision was never the point. Fixing the spine properly is.
Frequently Asked Questions
Is minimally invasive spine surgery always better than open surgery?
No, complex deformities and multilevel disease often need an open approach instead.
Does minimally invasive spine surgery mean faster recovery?
Usually yes, less muscle damage means most patients recover and return sooner.
Can every spine condition be treated minimally invasively?
No, severe deformity, revision and multilevel cases often require open surgery.
Is open spine surgery outdated?
No, it remains the safest choice for complex and large-scale spinal procedures.
