Treated: a 4-year-old California boy with VATER syndrome, a condition resulting in fused ribs, which caused a bump on his chest and a spinal curvature that leaves his head tilted and his back shaped like a question mark.

The procedure planned for her is electrical stimulation of her brain, while a titanium rod is implanted in the boy's ribs.
