Research & Innovation
Signature Techniques
Named techniques and classifications developed or refined by Dr. Garg and his colleagues — each backed by published evidence.
Surgical innovation, in practice, means refining a difficult operation until it is safer and more reproducible — and naming the result so others can learn it.
- 01
Modified Posterior Vertebral Column Resection Modified PVCR
A refined approach to one of the most complex spine procedures, for severe and rigid spinal deformity — developed and refined at AIIMS over roughly seven years.
Published in The Spine Journal (2020); now drawing international recognition.

Active Apex Correction APC
A technique for Early-Onset Scoliosis (EOS) that actively corrects the deformity at its apex.
Multicentre evidence in Global Spine Journal (2024, Best Paper Award) and NASSJ (2025).
