The Coraco-Gleno-Scapular Line: A Simple Novel Tool for Assessing Glenoid Bone Defects.

Background: Treatment decisions for shoulder instability often necessitate surgical intervention, with glenoid bone loss being a key factor. Currently, various techniques exist to identify glenoid bone loss, each with its own advantages and disadvantages. This study introduces the Coraco-Gleno-Scapular (CGS) line as a tool for assessing critical glenoid bone defects.
