Relationship between coracoid apex position and anterior shoulder instability

Lower scGCA values, which indicate a more superior position of the coracoid apex relative to the glenoid center, are associated with ASI independently of other parameters. scGCA values below 34.5°, indicating a superiorly positioned coracoid apex, showed an 85.7% sensitivity and 73.3% specificity for ASI. Level of evidence: III.

Abstract

Lower scGCA values, which indicate a more superior position of the coracoid apex relative to the glenoid center, are associated with ASI independently of other parameters. scGCA values below 34.5°, indicating a superiorly positioned coracoid apex, showed an 85.7% sensitivity and 73.3% specificity for ASI. Level of evidence: III.
