Location of the Optimized Centerline of the Glenoid Vault: A Comparison of Two Operative Techniques with Use of Three-Dimensional Computer Modeling

Abstract

The normal glenoid vault centerline is directed from lateral-posterior to medial-anterior, and it crosses, on the average, close to the glenoid face center. The neutralization direction, on the average, anteverts the glenoid relative to the vault centerline and the face plane perpendicular. Relationships between these directions vary across the subjects.
