Material analysis revealed a superficial abnormality on the upper neck surface caused by local melting with electrocautery probably acting as a stress amplifier. This lesion presumably was the trigger of a fatigue fracture with typical features on the fracture surface. Electrocautery should therefore be avoided in case of revision THA or used with utmost care to avoid contact with the femoral stem<\/jats:p>","DOI":"10.1136\/bcr-2021-247293","type":"journal-article","created":{"date-parts":[[2022,5,23]],"date-time":"2022-05-23T12:51:43Z","timestamp":1653310303000},"page":"e247293","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Fracture of a titanium femoral neck after revision total hip arthroplasty"],"prefix":"10.1136","volume":"15","author":[{"given":"Alexander","family":"Zimmerer","sequence":"first","affiliation":[{"name":"Department of Orthopaedics, ARCUS Kliniken, Pforzheim, Germany"},{"name":"Department of Orthopaedics and Orthopaedic Surgery, University Medicine Greifswald, Greifswald, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philips","family":"Ogunleye","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, ARCUS Kliniken, Pforzheim, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luis","family":"Navas","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, ARCUS Kliniken, Pforzheim, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matthias","family":"Hauschild","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, ARCUS Kliniken, Pforzheim, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2022,5,10]]},"reference":[{"key":"2025082712550231000_15.5.e247293.1","doi-asserted-by":"crossref","first-page":"173","DOI":"10.1055\/a-1028-7822","article-title":"Trends in total hip arthroplasty in Germany from 2007 to 2016: what has changed and where are we now?","volume":"159","author":"Klug","year":"2021","journal-title":"Z Orthop Unfall"},{"key":"2025082712550231000_15.5.e247293.2","unstructured":"Depuy.
