This is an posterior-to-anterior X-ray of a case of adolescent idiopathic scoliosis – specifically, my spine. There is a thoracic curve of 30° and a lumbar curve of 53° (Cobb angle – see scoliosis). This was taken at the Royal National Orthopaedic Hospital. The largest curve (53°) is of a magnitude typically near the lower surgery boundary, although many factors decide whether surgery is necessary on a scoliosis case. | Silverjonny – http://en.wikipedia.org/wiki/Image:Wiki_pre-op.jpg, Public Domain, https://commons.wikimedia.org/w/index.php?curid=1493715
