miRNA analysis to discover fracture related biomarkers 2 (miDiag2)

Background

Biomarkers predictive of fracture healing outcomes would provide a useful tool to allow surgeons to proactively make patient based clinical decisions. Currently, even in high risk groups, there are no accurate ways to determine the potential of a particular patients risk of delayed or non-union. Development of a predictive tool would enable more reliable patient stratification, thus allowing for earlier diagnosis and increasing the potential success of additional early interventions by the surgeon.

 

 

Goal

In a previous AOTrauma project (MiDiag) we investigated and correlated changes in small non-coding RNA profiles in fracture patients and during osteogenic differentiation.  A panel of prospective markers were identified, and this now requires further validation. In addition, we aim to use the methods developed, and the database of patient serum non-coding RNA created, to further investigate markers that are mechanically regulated and would be associated with secondary bone healing.
