Medialized designs have historically decreased glenosphere loosening but increase scapular notching, and lateralized designs decrease notching and improve range of motion but historically have resulted in increased baseplate failure. As such, a concrete conclusion with regard to medialization or lateralization of the glenosphere cannot be made at this time.<\/jats:p>\n                      <\/jats:list-item>\n                      <jats:list-item>\n                        <jats:p>\u27a2 Caudal, inferior placement of the glenosphere increases internal rotation, external rotation, abduction, and adduction while reducing notching. Superior baseplate positioning and tilt are correlated with baseplate failure and therefore should be avoided. It remains unclear whether neutral or slightly inferior tilt is preferred.<\/jats:p>\n                      <\/jats:list-item>\n                      <jats:list-item>\n                        <jats:p>\u27a2 The ideal humerosocket inclination angle remains unclear. The 135\u00b0 designs appear to have a lower rate of scapular notching than the Grammont-style 155\u00b0 humerosockets. The implications of this angle for instability remain unclear as, to our knowledge, there have been no randomized comparisons and the largest meta-analysis was confounded by other implant variables.<\/jats:p>\n                      <\/jats:list-item>\n                    <\/jats:list>\n                  <\/jats:p>","DOI":"10.2106\/jbjs.rvw.15.00070","type":"journal-article","created":{"date-parts":[[2016,6,15]],"date-time":"2016-06-15T09:26:32Z","timestamp":1465982792000},"source":"Crossref","is-referenced-by-count":20,"title":["Current Controversies in Reverse Total Shoulder Arthroplasty"],"prefix":"10.2106","volume":"4","author":[{"given":"Jessica L.","family":"Churchill","sequence":"first","affiliation":[{"name":"Eastern Virginia Medical School, Norfolk, Virginia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Grant E.","family":"Garrigues","sequence":"additional","affiliation":[{"name":"Division of Sports Medicine and Shoulder Surgery, Department of Orthopaedic Surgery, Duke University Medical Center, Durham, North Carolina"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"issue":"Suppl 1","key":"r1-20230812","first-page":"112","article-title":"[Results of Grammont\u2019s inverted prosthesis in omarthritis associated with major cuff destruction.
