Scoliosis, a condition that causes the spine to curve too much in the wrong direction, affects about 6 million people in the United States. Scoliosis develops gradually and often is not detected until a child is between 10 and 14 years old. In their Keeping Kids Healthy column, UTMB Drs. Sally Robinson and Keith Bly wrote about the signs and symptoms of scoliosis, which include uneven shoulders, one shoulder blade that sticks out further than the other, uneven waist, one hip higher than the other and leaning to one side. Several risk factors can affect the chance that a scoliosis curve will get worse.
