After placing the glenosphere with Univers Revers, which tool verifies Morse taper engagement?

• A. Torque wrench
• B. Glenosphere forceps with a linear pull
• C. Pliers
• D. Calipers

Answer: (B)

Morse taper engagement is confirmed by a deliberate axial seating check: you need to apply an axial pull to verify the glenosphere is fully seated onto the baseplate taper so there’s no remaining gap and the component cannot be removed with a gentle pull. The instrument designed for this step in the Univers Revers system is the glenosphere forceps with a linear pull, which provides a controlled, straight-line force to test true engagement without introducing rotational torque or damage. A torque wrench tests rotational fixation, not taper seating; pliers risk damaging the taper, and calipers cannot assess whether the taper is fully seated.
