Currently the measurement of serum or synovial biomarkers does not have a role in diagnosis or monitoring of injury severity in young patients with recurrent anterior shoulder instability. The purpose of this study was to compare gene expression differences in the peripheral blood and tissue of young patients with recurrent anterior shoulder instability with and without significant glenoid bone loss (GBL). Additionally, we sought to determine a peripheral blood transcriptomic biomarker for the reliable delineation of the severity of GBL in anterior shoulder instability patients.

There are significant gene expression differences in the peripheral blood of anterior shoulder instability patients with and without significant (≥10%) GBL. The differential expression of 5 genes allowed development of an accurate predictive model and transcriptomic classifier to predict the severity of GBL. This novel peripheral blood transcriptomic biomarker may assist in tracking glenoid bone loss and injury severity and progression in young patients with recurrent anterior shoulder instability.
