Editorial Commentary: Bone Loss in Shoulder Instability Occurs in 3 Dimensions

The continued debate regarding the appropriate threshold to consider performing bony stabilization procedures in the treatment of shoulder instability has contributed to a recent boom of new research in this area. The contribution of both glenoid bone loss and version in predicting potential clinical failure after soft tissue stabilization is one of those topics. The authors of the featured study demonstrate the relationship between measured glenoid version and bone loss, which can assist us in our clinical decision making. To date, most measures of glenoid version have been reported based on analysis of 2 dimensions. However, with 2-dimensional analysis, bone loss may result in potentially errant measurement of version and require subsequent correction. Moreover, 3-dimensional analysis could result in a more nuanced understanding of the complexities of glenoid pathologic study in patients with shoulder instability.
