title: Orthopaedic surgeons' strategies in pharmacological treatment of fragility fractures.
abstract: Fragility fractures are the most severe complications of osteoporosis and the poor mechanical properties of bone can make fixation and healing of these fracture extremely difficult. The role of orthopaedic surgeons does not end in skillful fixation of the fractures, but they have the unique opportunity to prevent complications which can negatively affect the patient's quality of life. The best practice for preventing the risk of further fractures in patients presenting fragility fractures includes fall prevention, investigation of possible causes underlying osteoporosis, attention to exercise, calcium and vitamin D supplementation as well as prescription of drugs. Actually two classes of agents can be used for their effect on fracture prevention: antiresorptive and bone forming agents. Systemic therapy reduces the risk of vertebral (30-70%) and non-vertebral fractures (12-53%), depending on agents and patients' compliance. Preclinical and clinical studies have shown that pharmacological agents involved in osteoporosis can also influence the phases of fracture repair. Preclinical studies and evidences from case reports showed a positive effect of anabolic drugs on bone healing and implant osseointegration. The interventions in the process of fracture healing had evolved from a diamond to a pentagon concept, with interactions between the mechanical environment, the local therapies, the vascularity of the fracture site, the biology of the host and the systemic therapy which has the potential to represent the fifth interaction factor. The orthopaedic surgeon plays a central role in clinical setting to evaluate the efficacy of systemic anti-fracture drugs for improving fracture repair and preventing complications.
