They concern about 4 to 5% of the patients and always result in a significant deterioration of shoulder function. Different causes have been taken into consideration, particularly stress or fatigue fractures. The purpose of the present study was to analyse our own cases and to discuss the causes reported in the literature.<\/jats:p>\n<\/jats:sec><jats:sec>\n<jats:title>Methods<\/jats:title>\n<jats:p>We reviewed our shoulder arthroplasty registry and the consultation reports of the last ten\u00a0years. The charts and radiographs of all patients who had a post-operative fracture of the acromion or the scapular spine were carefully examined and the results were compared with those of an age- and gender-matched control group.<\/jats:p>\n<\/jats:sec><jats:sec>\n<jats:title>Results<\/jats:title>\n<jats:p>Twelve patients with an average age of 79\u00a0years sustained a fracture of the acromion (<jats:italic>n<\/jats:italic>\u2009=\u20096) or the scapular spine (<jats:italic>n<\/jats:italic>\u2009=\u20096). The time interval between the operation and the fracture averaged 26\u00a0months and ranged from three\u00a0weeks to 70\u00a0months. Eight patients (67%) had a trauma. Seven of them reported a fall on the corresponding shoulder and one a heavy blow on the acromion. The four non-traumatic fractures were attributed to poor bone quality. All 12 patients had immediate pain and difficulty to actively elevate the affected arm. The time interval between the fracture and its diagnosis averaged ten\u00a0weeks (0 to 10\u00a0months). At final follow-up, all patients could reach their face and refused further surgery. Two patients rated their result as good, six as acceptable and four as poor.<\/jats:p>\n<\/jats:sec><jats:sec>\n<jats:title>Conclusions<\/jats:title>\n<jats:p>Our study cannot support the hypothesis that most acromion and scapular spine fractures after RSA are the result of increased tension in the deltoid or stress fractures. In our series, the majority of the fractures were related to a fall. Implantation of a reverse prosthesis exposes the acromion and makes it more vulnerable to direct trauma. Non-traumatic fractures were associated with poor bone quality.<\/jats:p>\n<\/jats:sec>","DOI":"10.1007\/s00264-020-04813-5","type":"journal-article","created":{"date-parts":[[2020,9,29]],"date-time":"2020-09-29T20:03:00Z","timestamp":1601409780000},"page":"2673-2681","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":35,"title":["Causes of acromion and scapular spine fractures following reverse shoulder arthroplasty: a retrospective analysis and literature review"],"prefix":"10.1007","volume":"44","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0376-5650","authenticated-orcid":false,"given":"Richard W.","family":"Nyffeler","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bartu","family":"Altioklar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philipp","family":"Bissig","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2020,9,29]]},"reference":[{"key":"4813_CR1","doi-asserted-by":"crossref","first-page":"527","DOI":"10.1016\/j.jse.2006.01.003","volume":"15","author":"P Boileau","year":"2006","unstructured":"Boileau P, Watkinson D, Hatzidakis AM, Hovorka I (2006) Neer Award 2005: the Grammont reverse shoulder prosthesis: results in cuff tear arthritis, fracture sequelae, and revision arthroplasty.
