Our Philosophy
Many patients don’t need surgery
Being told you need spine surgery is frightening — and often, it isn’t true. The first job is to find out whether you can get better without an operation. Surgery is a last resort, offered only when it’s genuinely the right answer.
That honesty is why patients travel across Chennai for a second opinion — and why so many leave relieved they never needed the operation they feared.
Surgery only when it's truly needed
Most back and neck pain settles without an operation. You'll be told honestly if you don't need one — and what to do instead.
The least invasive option that works
When surgery is needed, it's done through an 8 mm keyhole where possible — less pain, less blood loss, a much smaller scar.
Home and walking sooner
Many patients walk the same day and go home within 24 hours, instead of a long hospital stay and weeks of recovery.
Your spine keeps moving
Disc replacement and non-fusion scoliosis correction preserve movement, so your spine isn't permanently locked stiff.

Patient Stories
Trusted by patients across Chennai
“For 16 months I suffered immensely from low back pain. I saw countless doctors, had multiple MRI scans, physiotherapy, acupuncture — I tried everything. Every doctor blamed an L4-L5 disc bulge. Dr. Sasidharan carefully assessed my symptoms, concluded they did not fit that at all, and found the real cause. He suggested a targeted injection. Today I am 80% better and back to my daily activities. He saved me from unnecessary surgery, and from ineffective treatments based on mere assumptions.”

“I came to Dr. Sasidharan after six months of severe back ache with radiating sciatica. I had consulted ortho and neuro doctors and tried varma, ayurveda and acupuncture — none of it worked. He gave me a clear picture of the problem and the right solution. I had an endoscopic day-care procedure and was able to walk three hours after surgery, without the radiating pain. Seven days on, I sleep without pain.”

“Words are not enough to thank you for the care and expertise you showed during my daughter's spine surgery. As a parent it was a very stressful and emotional time, but your confidence, clear guidance and reassuring words gave us great comfort. Because of you, my daughter now has a hopeful path toward recovery and a healthier future.”
