What size revision stems are available for Univers Revers?

• A. 4, 8, and 12
• B. 5, 7, and 11
• C. 6, 9, and 12
• D. 7, 10, and 14

Answer: (C)

The question is about what revision stem sizes are available for the Univers Revers system. In revision shoulder arthroplasty, the stem needs to fit the humeral canal securely and accommodate varying bone stock and anatomy. Univers Revers provides three revision stem options to cover a range of canal sizes and achieve stable fixation, specifically sizes 6, 9, and 12. These three choices give the surgeon the ability to select a stem that achieves good centralization, proper seating, and appropriate limb alignment during revision. The other size triplets don’t reflect the actual revision stem lineup for this system, so they aren’t correct.
