Aim of our study was to review the characteristics of atypically located OO, course of symptoms and therapy, as well as clinical outcome, safety, and patient satisfaction of radiofrequency ablation (RFA).<\/jats:p><jats:p>\n            Materials and methods\u2002In the period from 04\/01 to 07\/13, 33 patients were treated using thermal ablation (RFA or laser), partly with low temperature and short duration technique. Clinical records were analyzed. Additionally, 23 patients were interviewed via telephone. Primary endpoints were technical success, clinical success (recurrence rates), and adverse events. Secondary endpoints were course of symptoms and therapy as well as patient satisfaction.<\/jats:p><jats:p>\n            Results\u2002Mean follow-up was 22.1\u200a\u00b1\u200a21.5 months. Average patient age was 31.7\u200a\u00b1\u200a16.3 years. Localization: Most atypical OO (61\u200a%) were located in the lower extremity, followed by axial skeleton (26\u200a%) and upper extremity (13\u200a%). Pain anamnesis: 74\u200a% of patients stated that their pain occured predominantly at night and responded to NSAID, as typical for OO. Diagnostics: Patients consulted on average 4 different doctors and in 52\u200a% patients, \u2265\u200a3 different radiologic imaging techniques where used before the diagnosis \u201cOO\u201d was made. Outcome: Technical success of thermal ablation was 100\u200a%. Primary clinical success was 91\u200a%. Patient satisfaction was 100\u200a%. No major complications occurred.<\/jats:p><jats:p>\n            Conclusion\u2002In \u00bc of cases, atypical OO did not show the typical pain characteristics of OO. Image-guided thermal ablation is a promising and safe therapy also for patients with atypical OO.<\/jats:p><jats:p>\n            Key points:\u2002<\/jats:p><jats:p>\n            Citation Format\n          <\/jats:p>","DOI":"10.1055\/a-1012-2143","type":"journal-article","created":{"date-parts":[[2019,11,20]],"date-time":"2019-11-20T23:49:19Z","timestamp":1574293759000},"page":"335-342","source":"Crossref","is-referenced-by-count":5,"title":["Atypically Located Osteoid Osteoma: Characteristics and Therapeutic\u00a0Success After Image-Guided Thermal Ablation"],"prefix":"10.1055","volume":"192","author":[{"given":"Ricarda Johanna","family":"Seemann","sequence":"additional","affiliation":[{"name":"Center for Muskuloskeletal Surgery, Charit\u00e9 \u2013 University Medicine Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sven","family":"M\u00e4rdian","sequence":"additional","affiliation":[{"name":"Center for Muskuloskeletal Surgery, Charit\u00e9 \u2013 University Medicine Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philipp","family":"Schwabe","sequence":"additional","affiliation":[{"name":"Department for Trauma and Orthopaedic Surgery, Vivantes-Hospital Spandau, Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Florian","family":"Streitparth","sequence":"additional","affiliation":[{"name":"Department of Radiology, Ludwig-Maximilians-University Munich, M\u00fcnchen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2019,11,20]]},"container-title":["R\u00f6Fo - Fortschritte auf dem Gebiet der R\u00f6ntgenstrahlen und der bildgebenden Verfahren"],"original-title":[],"language":"de","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/a-1012-2143.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,3,18]],"date-time":"2020-03-18T23:34:25Z","timestamp":1584574465000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/a-1012-2143"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,11,20]]},"references-count":0,"journal-issue":{"issue":"04","published-online":{"date-parts":[[2020,3,18]]},"published-print":{"date-parts":[[2020,4]]}},"URL":"https:\/\/doi.org\/10.1055\/a-1012-2143","relation":{},"ISSN":["1438-9029","1438-9010"],"issn-type":[{"value":"1438-9029","type":"print"},{"value":"1438-9010","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,11,20]]}}}
