Deepak Kumar on Instagram: "Halo-gravity traction is a medical procedure for kids with severe scoliosis or kyphosis. A halo ring is attached to the skull with pins, connected to a pulley system with weights. This gently stretches the spine over weeks, reducing curvature before surgery. The video shows a child in traction, able to play while the device provides upward pull. It's supervised by doctors to improve alignment safely. #science #viral #reels #technology #innovation"
