Contemporary treatment for this condition has shifted toward the use of percutaneous ablation techniques. In this study, we aimed to evaluate the efficacy and safety of microwave ablation in patients with osteoid osteoma.\n\nMaterials and Methods: This retrospective study analysed 35 patients with osteoid osteoma treated using microwave ablation between June 2019 and June 2025. Patient demographics and clinical characteristics, such as tumour location, pain levels (assessed using the Visual Analogue Scale [VAS]), complications, and hospital stay, were recorded and analysed using descriptive statistics.\n\nResults: The average patient age was 18.08 \u00b1 8.6 years, and the proximal femur was the most commonly affected site (9\/35 patients [27%]). Microwave ablation significantly reduced pain in 34 of 35 patients (97.1%), with average VAS scores decreasing from 7.4 \u00b1 0.94 to 1.9 \u00b1 0.7 after the procedure. Complications occurred in 5 of 35 patients (14.3%), and the average hospital stay was 3 days.\n\nConclusion: Our retrospective analysis showed that microwave ablation helped achieve significant pain reduction in patients with osteoid osteoma. While the procedure demonstrates efficacy, caution is necessary to minimise the risk of thermal injury to surrounding non-target tissues.\n\nKeywords: Bone cancer, osteoid osteoma, radiofrequency ablation, microwave radiation.<\/jats:p>","DOI":"10.13107\/jocr.2026.v16.i06.7400","type":"journal-article","created":{"date-parts":[[2026,6,9]],"date-time":"2026-06-09T15:16:19Z","timestamp":1781018179000},"page":"122-127","source":"Crossref","is-referenced-by-count":0,"title":["Efficacy and Safety of Microwave Ablation for Osteoid Osteoma: A Retrospective Analysis of 35 Cases"],"prefix":"10.13107","volume":"16","author":[{"given":"Dijoe","family":"Davis","sequence":"first","affiliation":[{"name":"Department of Orthopaedics, Amala Institute of Medical Sciences, Thrissur, Kerala, India,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jijoe","family":"John","sequence":"additional","affiliation":[{"name":"Department of Radiodiagnosis, Amala Institute of Medical Sciences, Thrissur, Kerala, India."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ajith","family":"John","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Amala Institute of Medical Sciences, Thrissur, Kerala, India,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K Dominic","family":"Puthur","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Amala Institute of Medical Sciences, Thrissur, Kerala, India,"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"5271","published-online":{"date-parts":[[2026]]},"container-title":["Journal of Orthopaedic Case Reports"],"original-title":[],"deposited":{"date-parts":[[2026,6,9]],"date-time":"2026-06-09T15:16:20Z","timestamp":1781018180000},"score":1,"resource":{"primary":{"URL":"https:\/\/jocr.co.in\/wp\/2026\/06\/efficacy-and-safety-of-microwave-ablation-for-osteoid-osteoma-a-retrospective-analysis-of-35-cases\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026]]},"references-count":0,"journal-issue":{"issue":"6","published-online":{"date-parts":[[2026]]},"published-print":{"date-parts":[[2026]]}},"URL":"https:\/\/doi.org\/10.13107\/jocr.2026.v16.i06.7400","relation":{},"ISSN":["2321-3817"],"issn-type":[{"value":"2321-3817","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026]]}}}
