Are all Univers Revers Glenosphere sizes available in concentric, 3.5 inferior, and +4 offset?

Are all Univers Revers Glenosphere sizes available in concentric, 3.5 inferior, and +4 offset?

• A. True
• B. False
• C. Not all sizes have these offsets
• D. Only some sizes offer +4 offset

Answer: (A)

In reverse shoulder arthroplasty, offset options change where the center of rotation sits relative to the baseplate, which affects deltoid tension, ROM, and potential impingement. The Univers Revers Glenosphere line is designed so that every diameter size is available with all three offset configurations: concentric (no offset), a 3.5 mm inferior offset (lowering the center of rotation to improve inferior overhang and reduce scapular notching), and a +4 mm offset (lateralizing the center to tweak tension and ROM). Because these offsets are offered across the entire size range, any glenosphere size can be chosen with any of these offsets. That’s why the statement is true.
