 The optional, interventional arm of this study will assess bone quality in the proximal humerus of a fracture patient population. DXA is not particularly effective at identifying individuals who are at risk of suffering a fracture. Yet, there is a growing population of diabetics and elderly individuals prone to fragility fractures. In effect, the age-related and diabetes-related increase in fracture risk is independent of a persons aBMD. These findings stress the urgency in developing diagnostic tools that can improve fracture risk prediction so that patients can be treated with the appropriate anti-fracture therapies.
