Which statement is true when comparing standard glenoid components with Vaultlock?

• A. The Radius of curvature are different for vaultlock
• B. The Standard wire goes through central peg
• C. Trial components for standard glenoid and vaultlock are the same
• D. All of the above

Answer: (A)

The key idea here is that the glenoid’s curvature is a fundamental geometric detail that affects how the implant seats and articulates. Vaultlock glenoids are designed with a different radius of curvature than standard glenoid components to accommodate its locking mechanism and to maintain proper contact with the humeral head. This change in curvature helps ensure the insert seats correctly, distributes load more evenly, and supports stable fixation with the Vaultlock design.

The other statements don’t hold because the Vaultlock system uses its own distinct trial geometry and locking features, not identical to the standard glenoid. The notion of a wire passing through a central peg isn’t a defining or universal aspect of Vaultlock, and the trial components for the two designs are not the same, given the differing curvature and locking geometry.
