The failure has been in the form of corrosion, metallosis, fretting and trunnion fracture. This paper explores 10 cases with trunnion failure.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>A retrospective retrieval analysis of ten femoral stems retrieved at four different centres across Western Australia over a 3-year time frame.

Average in situ time was 8.9\u2009years. The hips were revised for either trunnion dislocation (6 cases) or trunnion fracture (4 cases). A characteristic destructive wear pattern of the femoral taper (trunnion) a \u201cbird beak\u201d appearance was present in all stems. This wear pattern created excessive movement and loosening resulting in a trunnion\/head dislocation or brittle fracture of the trunnion.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Catastrophic femoral neck fracture was likely due to a combination of material composition mismatch and mechanically assisted fretting corrosion at the head-neck junction leading to gross metallosis and failure. We suggest a recall on patients with an Accolade 1 stems in combination with a 36-mm or above LFIT or MITCH head, and for these patients to have clinical and radiological review.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/1120700020919665","type":"journal-article","created":{"date-parts":[[2020,4,23]],"date-time":"2020-04-23T06:46:40Z","timestamp":1587624400000},"page":"481-487","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":17,"title":["Catastrophic failure of the Accolade I hip arthroplasty stem: a retrieval analysis study"],"prefix":"10.1177","volume":"30","author":[{"given":"Christopher W","family":"Wylde","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Fremantle Hospital and Health Service, Palmyra, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elizabeth","family":"Jenkins","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Fremantle Hospital and Health Service, Palmyra, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Moreica","family":"Pabbruwe","sequence":"additional","affiliation":[{"name":"Centre for Implant Technology and Retrieval Analysis, Department of Medical Engineering and Physics, Royal Perth Hospital, Perth, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Bucher","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Fiona Stanley Hospital, Murdoch, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2020,4,23]]},"reference":[{"key":"bibr1-1120700020919665","doi-asserted-by":"publisher","DOI":"10.5435\/JAAOS-20-04-214"},{"key":"bibr2-1120700020919665","doi-asserted-by":"publisher","DOI":"10.3928\/01477447-20140528-62"},{"key":"bibr3-1120700020919665","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-015-4438-z"},{"key":"bibr4-1120700020919665","doi-asserted-by":"publisher","DOI":"10.1016\/j.arth.2014.11.023"},{"key":"bibr5-1120700020919665","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.CC.N.00179"},{"key":"bibr6-1120700020919665","unstructured":"Australian Orthopaedic Association National Joint Replacement Registry.
