Long-term Reverse Total Shoulder Arthroplasty Outcomes: The Effect of the Inferior Shifting of Glenoid Component Fixation
Abstract
fective treatment option for a wide assortment of shoulder pathologies. The Grammont design, with a neck-shaft angle of 155° and a medialized center of rotation, has a long track record in terms of both pain relief, as well as improved range of motion (ROM). Long-term followup has revealed issues, however, with scapular notching and progressively worsening clinical outcomes. In an attempt to reduce the notching rate, a variety of implant designs and surgical techniques have been employed. Nyffeler et al. placed a 29-mm baseplate precisely at the inferior rim with a 36-mm sphere, which allows an inferior glenoid component overhang (IGO) of 3.5 mm.
