• Surgery with posterior spinal fusion is indicated when the degree of the curve (known as the Cobb angle) is greater than 20° in boys who have not yet stopped growing and who are not taking steroids. The aim of surgery is to preserve the best possible posture for comfort and function. When boys are taking steroids, there is less risk of deterioration and the decision to proceed to surgery can be left until the Cobb angle is greater than 40°.
  • It is important to discuss what type of operation is needed with your surgeon and express any concerns you may have.
