Background: For the treatment of disturbed fracture healing, drugs could be given in addition to surgical procedures. Specific osteoporosis drugs affect the bone metabolism and are used to treat osteoporosis, particularly after a fragility fracture has occurred. Therefore, their use would be conceivable to improve a disturbed fracture healing.
Objective: This article presents the available and upcoming specific osteoporosis drugs and investigates whether these substances affect fracture healing in the context of osteoporosis. Furthermore, it is discussed whether disturbed fracture healing can be improved by the use of these substances.
Material and methods: A literature search (PubMed) was conducted using key terms. Preclinical studies, clinical studies, reviews and meta-analyses were considered in order to present the current knowledge in a clinically relevant context.
Results: Preclinical and clinical studies show that specific osteoporosis drugs have no relevant negative impact on the healing of fragility fractures. A tendency to improve a disturbed fracture healing was attributed to bone anabolic substances; however, studies are inconsistent and there is no approval for this application.
Conclusion: Following a fragility fracture, osteoporosis should be diagnosed according to the guidelines and, if necessary, treated with specific osteoporosis drugs, since in principle they do not impair fracture healing but significantly reduce the risk of subsequent fractures. Approval to improve fracture healing requires further investigations.
