We know that fracture is quite common in the community. We also know that fracture increases the risk of death. Our latest work suggests that multimorbidity can explain why patients with a fracture have higher risk of death. A few years ago my 70-year old neighbour broke his hip after…

I am incredibly honored and humbled to be appointed as a Member of the Order of Australia (AM). It came with a total surprise. …

In a previous blog, I discussed the implication of communicating mortality risk to patients with a fracture. In this article, we put forward the new concept of “skeletal age” to quantify the impact of fracture on mortality. It is easy to determine the chronological age of an individual. The number…
