Which instrument ensures proper Morse taper engagement of the glenosphere?

• A. Suture Forceps
• B. Plate Graspers
• C. Humeral Inserter
• D. Glenosphere Forceps

Answer: (D)

Engaging a Morse taper requires precise alignment and a deliberate, axial push to slide the tapered male into the female until seating is complete. The glenosphere forceps are built to hold the glenosphere firmly and allow controlled guidance onto the taper, delivering the appropriate axial force without slipping or tilting. This ensures the taper engages fully and the glenosphere sits flush against the baseplate. Other tools listed serve different tasks—suture forceps for soft tissue suturing, plate graspers for handling plates, and the humeral inserter for the humeral component—not for seating the glenosphere onto its Morse taper. Using the dedicated glenosphere forceps minimizes risk of misalignment or incomplete engagement, which is essential for the stability of the reverse shoulder construct.
