We present a case of MO involving the thenar eminence, initially suspected and managed as an accessory trapezium fracture.\n\nCase Report:\nA 66-year-old male presented with acute pain and swelling in the base of his left thumb. Initial imaging suggested a possible accessory trapezium fracture, prompting immobilization and conservative management. Subsequent clinical course and imaging over weeks revealed resorption of the calcification on follow-up radiographs, consistent with MO rather than a fracture.\n\nDiscussion:\nThis case highlights the diagnostic challenges posed by MO in the upper extremities and underscores the importance of serial imaging and clinical correlation in distinguishing it from other conditions, particularly fractures, to guide appropriate management.\n\nConclusion:\nPhysicians are encouraged to consider MO as a possible diagnosis for soft-tissue swelling of the hand.\n\nKeywords:\nMyositis ossificans , Thenar eminence , trapezium , accessory bone<\/jats:p>","DOI":"10.13107\/jocr.2026.v16.i10.8196","type":"journal-article","created":{"date-parts":[[2026,10,7]],"date-time":"2026-10-07T09:18:02Z","timestamp":1791364682000},"page":"86-89","source":"Crossref","is-referenced-by-count":0,"title":["Myositis Ossificans of the Thenar Eminence mimicking a Fracture of an Accessory Trapezium: A Case Report"],"prefix":"10.13107","volume":"16","author":[{"given":"Wendy","family":"Ghanem","sequence":"first","affiliation":[{"name":"Department of Orthopedics and Traumatology, Faculty of Medicine, University of Balamand, Beirut, Lebanon"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fouad","family":"Jabbour","sequence":"additional","affiliation":[{"name":"Department of Orthopedics and Traumatology, Saint George Hospital University Medical Center, Beirut, Lebanon"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hicham","family":"AbdelNour","sequence":"additional","affiliation":[{"name":"Department of Orthopedics and Traumatology, Saint George Hospital University Medical Center, Beirut, Lebanon"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hady","family":"Ezzeddine","sequence":"additional","affiliation":[{"name":"Department of Orthopedics and Traumatology, Faculty of Medicine, University of Balamand, Beirut, Lebanon"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sami","family":"Faddoul","sequence":"additional","affiliation":[{"name":"Department of Radiology, Faculty of Medicine, University of Balamand, Beirut, Lebanon"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ramzi","family":"Moucharafieh","sequence":"additional","affiliation":[{"name":"Department of Orthopedics and Traumatology, Faculty of Medicine, University of Balamand, Beirut, Lebanon 4 Department of Orthopedics and Traumatology, Clemenceau Medical Center, Beirut, Lebanon"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"5271","published-online":{"date-parts":[[2026]]},"container-title":["Journal of Orthopaedic Case Reports"],"original-title":[],"deposited":{"date-parts":[[2026,10,7]],"date-time":"2026-10-07T09:18:03Z","timestamp":1791364683000},"score":1,"resource":{"primary":{"URL":"https:\/\/jocr.co.in\/wp\/2026\/10\/myositis-ossificans-of-the-thenar-eminence-mimicking-a-fracture-of-an-accessory-trapezium-a-case-report\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026]]},"references-count":0,"journal-issue":{"issue":"10","published-online":{"date-parts":[[2026]]},"published-print":{"date-parts":[[2026]]}},"URL":"https:\/\/doi.org\/10.13107\/jocr.2026.v16.i10.8196","relation":{},"ISSN":["2321-3817"],"issn-type":[{"value":"2321-3817","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026]]}}}
