An overall humeral complication rate of 1.9% was identified, whereas short stems reported no humeral fractures or stem loosening. Infections (1.3%) proved to be the most common reason for component revision, and instability had a complication rate of 0.8%.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Level of evidence<\/jats:title>\n                <jats:p>Systematic review IV<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s10195-021-00592-w","type":"journal-article","created":{"date-parts":[[2021,7,8]],"date-time":"2021-07-08T07:03:14Z","timestamp":1625727794000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Problems, complications, and reinterventions in 4893 onlay humeral lateralized reverse shoulder arthroplasties: a systematic review (part I\u2014complications)"],"prefix":"10.1186","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7874-4531","authenticated-orcid":false,"given":"Francesco","family":"Ascione","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alfredo","family":"Schiavone Panni","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adriano","family":"Braile","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katia","family":"Corona","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giuseppe","family":"Toro","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicola","family":"Capuano","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alfonso M.","family":"Romano","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2021,7,8]]},"reference":[{"key":"592_CR1","doi-asserted-by":"publisher","first-page":"S147","DOI":"10.1016\/j.jse.2004.10.006","volume":"14","author":"P Boileau","year":"2005","unstructured":"Boileau P, Watkinson DJ, Hatzidakis AM, Balg F (2005) Grammont reverse prosthesis: design, rationale, and biomechanics.
