Abstract
Bone non-union following fracture is a major cause of morbidity in combat casualties.
The various clinical treatments used to prevent or treat non-union remain of limited efficacy. Research therefore continues in pre-clinical animal models in an attempt to identify an effective clinical treatment. The aim of this study was to systematically evaluate emerging pre-clinical therapies in order to rationalise priorities for translational research.
The methodological protocol of this study was registered with the Collaborative Approach to Meta Analysis and Review of Animal Data from Experimental Studies (CAMARADES) and published.
The review identified 3251 animal studies, 851 of which fulfilled the criteria for inclusion as detailed in the protocol. Of these, 702 of the studies described therapies that had progressed to clinical trials and were therefore excluded. The remaining 149 papers described eighteen categories of therapy that represent novel therapies yet to translate to clinical trials. These studies used a range of animal models, with heterogeneity that precluded formal synthesis and meta-analysis.
This study provides a systematic evaluation of novel therapies with potential to prevent or treat non-union. It also represents a novel application of an emerging epidemiological technique to address a key priority in Combat Casualty Care research.
