Technology behind augmenting fracture healing

Despite bone's robust regenerative capacity, complications such as delayed union and nonunion affect 5-10% of fractures, with significant clinical and economic burdens. The rising incidence of fractures, particularly in an aging population, highlights the importance of optimizing fracture healing strategies. This review explores current therapies aimed at enhancing bone regeneration, focusing on 2 main categories: local biologic therapies and mechanical therapies. Local biologic treatments, including concentrated bone marrow aspirate, platelet-rich plasma, bone morphogenetic proteins, and platelet-derived growth factor, aim to stimulate osteogenesis at the fracture site. Therapies, such as electrical stimulation, low-intensity pulsed ultrasound, and extracorporeal shockwave therapy, are theorized to modify the mechanical environment to promote healing. Although these therapies show promise, variability in clinical outcomes emphasizes the need for further research to standardize protocols and refine treatment strategies. Overall, advancing our understanding of bone healing mechanisms will continue to drive innovation in fracture management, improving patient outcomes and reducing health care costs.
