Steroid treatment is known to add to the risk of low bone density and is also associated with the risk of fractures of the spinal vertebrae. Fractures of the vertebrae are not usually seen in non-steroid treated boys. Bone density may need to be assessed with blood tests, bone scans and other X-rays (see bone health management). This is an area where further research is needed to establish the parameters for best practice.
