In orthopaedics, focus is often placed on increasing bone formation by an anabolic drug like the recombinant human bone morphogenetic protein (rhBMP). However, premature or excessive bone resorption, due to stress-shielding, instability or infection/inflammation can lead to poor, delayed, or absent bone union. Anti-catabolic drugs such as bisphosphonates have therefore been explored to improve bone repair. This short review discusses the current literature underlying the anabolic-catabolic paradigm for bone repair with a focus on BMP and bisphosphonate combination approaches.
