All Univers Revers Glenosphere sizes are available in concentric, 3.5 inferior, and +4 offset.

All Univers Revers Glenosphere sizes are 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)

Univers Revers Glenosphere sizing is designed so that every size can be obtained with the same three offset configurations: concentric (centered), inferior offset of 3.5 mm, and +4 mm offset. This setup lets the surgeon tailor the center of rotation and deltoid tension to the patient’s anatomy across the entire size range. The concentric option keeps the glenosphere aligned directly with the baseplate, providing standard biomechanics. The inferior offset of 3.5 mm lowers the center of rotation a bit, which can improve inferior stability and help reduce impingement or notching. The +4 mm offset lateralizes the glenosphere, increasing deltoid wrapping and stability, often enhancing range of motion while maintaining clearance. Because these offsets are available for every size, intraoperative customization is possible without being limited by size.
