Other diagnoses, including non-specified reasons for THA revision in the chosen studies, accounted for 9.2% (127\/1,386). The total mean was a union rate of 95.2%, an infection eradication rate of 91.6%, a femoral stem subsidence rate of 16.6%, with the rate of subsidence more than 5\u00a0mm being 10.7%. ETO proximal migration was reported in 7.8% of ETOs; however, it rarely required re-attachment (0.9%). Intraoperative fracture during revision THA with ETO was reported to be at a rate of 5%; while postoperative femoral fracture rate was at 7.8%.<\/jats:p>\n                <jats:p>(2) All 24 cases had radiographic union at 3 to 6\u00a0months and there was no reported femoral stem subsidence.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>The overall outcome of this literature review provides moderate-quality evidence indicating that ETO provides safe outcome for revision THAs in single and 2-stage revision surgeries with low ETO non-union, femoral stem subsidence, greater trochanter (GT) proximal migration and fracture rates in the different diagnoses groups of revision THA at over 2-year follow up. In the case series group, there was radiographic union of all ETOs with no reported femoral stem subsidence or periprosthetic fractures.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s42836-022-00115-w","type":"journal-article","created":{"date-parts":[[2022,4,3]],"date-time":"2022-04-03T00:03:37Z","timestamp":1648944217000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Extended trochanteric osteotomy in revision hip arthroplasty: a case series study and systematic literature review"],"prefix":"10.1186","volume":"4","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5603-0706","authenticated-orcid":false,"given":"Khalid","family":"Hamad","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sujith","family":"Konan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2022,4,3]]},"reference":[{"issue":"2","key":"115_CR1","first-page":"94","volume":"29","author":"V.
