    • changes in the vertebrae as they rotate and move
    • Congenital
    • When curvature reaches 60* cardiopulmonary compromise results (life threatening)
    • Spinal Instability at 50* (needs surgery)
  55. Scoliosis is frequent in
  56. Surgical for scoliosis
    • <50 curvature indicates conservative treatment

  60. hyperparathyroid causes
    calcium  to be released from the bone into the blood
