Spinal deformity occurs when the curves of the spine differ from the normal, gentle S-shape seen from the side, or the straight line down the back of a normal spine. Spinal deformities, including scoliosis, may lead to symptoms that include pain, weakness, numbness, tingling, loss of function, and pulmonary and cardiac problems. The experts at Och Spine at NewYork-Presbyterian/Weill Cornell Medical Center create individual treatment plans based on each patient's needs.
