Our group studies the outcomes of many important orthopaedic conditions. We are using large clinical databases to study rare femur fractures, uncommon hip infections, and novel fracture treatments. The goal is to provide clinical insight into conditions which could not be studied in traditional clinical studies.

We are also interested in atypical fractures of the femur. We are currently recruiting for a clinical trial in which we screen long-term bisphosphonate users for the radiographic markers of atypical femur fractures. The study is designed to determine who is at risk and to further our understanding of the biology of these rare fractures. For further details on this study please click here.
