PRIMA Stem Surgical technique
Insertion of final PRIMA reverse insert
Open the packaging of the reverse insert that was selected during the trial reduction. Clean the PRIMA Stem and impact the insert on the stem by means of the reverse insert pusher assembled to the handle (Figure 46). If a 7° or an offset reverse insert is chosen, make sure to align the marking on the insert to the marking performed during trialing phase (Figure 47). Make sure that the contact surfaces are perfectly clean and that the insert does not contact the bone, as this could compromise the stability of the morse taper coupling. The shoulder joint may then be reduced with gentle manipulation, with or without use of the Namba slide.
