Automatic Glenoid Bone Loss Detection and Quantification in Shoulder CT Scans

Estimation of glenoid bone loss following shoulder dislocation in a CT scan is often required to determine the appropriate surgery needed to restore shoulder stability [1]. Currently, the best method for measuring glenoid bone loss has not been universally defined, so various methods have been proposed [2,3]. They can be grouped into linear-based (most methods) and area-based measurement methods, without (standalone) or with a comparison with the healthy contralateral glenoid, which is not always included in the CT scan. In all cases, the measurements are performed manually, which is time-consuming, requires expertise, and is subject to observer variability. This paper presents a novel automatic standalone linear-based method for glenoid bone loss quantification in shoulder CT scans.
