A 15-year-old boy has three extra vertebrae in his neck - a condition known as supernumerary vertebra along with congenital scoliosis - causing pain, stress on his nerves, and making it difficult for him to walk. The extra vertebrae press on his nerves in his neck and make it difficult for him to walk. Currently, he doesn’t like to go out anymore because his condition attracts attention from strangers as he struggles to walk. The Chinese teen is expected to undergo a surgical procedure that may include spinal fusion and hemivertebra removal. In spinal fusion, the abnormal curved vertebrae are fused together so that they heal into a single, solid bone. This is able to stop the growth in the abnormal part of the spine, preventing the curve from getting worse. In hemivertebra removal, a single hemivertbra can be surgically removed, and then doctors use metal implants to correct the curve.
