JSES published "Polyethylene wear in retrieved reverse total shoulder components".
In seven reverse total shoulders requiring revision, all seven polyethylene components showed evidence of rim wear, which may arise from contact of the poly with lateral glenoid bone or the glenoid fixation screws. This topic is discussed the other post from today and from earlier.
Because of concern for polyethylene wear, it may be worthwhile considering a reverse total shoulder technique that offsets the glenoid center from the glenoid bone.
