IntroductionThe improvement and acceleration of fracture healing has been a component of medical practice since fractures have been treated. The aim is not only to fulfill the basic principles of fracture healing, such as reduction, retention, soft tissue coverage and infection prevention but also to reduce negative influences on fracture healing and promote positive factors. Nicotine, alcohol, diabetes and malnutrition can negatively affect fracture healing and should be appropriately controlled during fracture treatment; however, it is far more difficult to develop medicinal treatment strategies that lead to improvement and acceleration of fracture healing.AimThis article provides an overview of pharmacological factors influencing fracture healing. In addition, substances frequently used in clinical practice will be evaluated in terms of the effects on fracture healing processes.Material And MethodsAn extensive literature search was conducted in PubMed based on thematic keywords. The selection of studies and scientific publications focused mainly on results from clinical trials in order to provide practically relevant information.ResultsIn this context, preclinical studies have identified several drugs that lead to the acceleration of fracture healing; however, only a very limited number of clinical trials have confirmed this positive effect. Most of these studies dealt with drugs developed for the treatment of osteoporosis, as osteoporotic fractures are common and a positive or negative influence of such drugs are of particular interest in this field. In the field of osteoporosis medication a certain degree of positive effect of parathyroid hormone 1-34 (PTH) on fracture healing has been shown in clinical trials. For other osteoporosis medications no negative influence on fracture healing in clinical settings has been reported; however, there seems to be a positive effect in terms of better implant fixation for patients receiving oral bisphosphonate therapy.DiscussionSystemic medication to improve fracture healing will not be part of the clinical routine in the foreseeable future as the available data for already approved drugs and drugs under development do not currently justify routine administration. However, the currently known data should encourage the potential of known medications to be completely exhausted in fracture healing studies as well as novel therapy options in the sense of positive effects on fracture healing in order to improve patient care.
