While three-dimensional (3D) printing has shown promise in upper extremity deformity correction, its application in chronic Monteggia lesions remains limited.\n\nCase Report:\nWe report the case of a 24-year-old male presenting with a 1-year history of forearm pain following failed surgical management of a Monteggia fracture. Radiographs revealed a Bado type I chronic Monteggia fracture-dislocation. A personalized 3D-printed osteotomy guide was designed from pre-operative computed tomography data to assist in corrective ulnar osteotomy. The surgical plan included implant removal, corrective osteotomy using a customized surgical guide, bone grafting, and annular ligament reconstruction if unstable radiocapitellar joint after correction. Postoperatively, the patient initially regained functional elbow motion but later developed oligotrophic non-union. Revision surgery with repeat bone grafting resulted in solid union and complete functional recovery.\n\nConclusion:\nThis case highlights the potential of 3D-assisted pre-operative planning and patient-specific guides in managing chronic Monteggia deformities. It contributes to the growing evidence supporting personalized surgical technologies in complex upper-limb reconstruction.\n\nKeywords:\nChronic Monteggia fracture-dislocations , corrective osteotomy , three-dimensional printing , surgical guide , customized plate<\/jats:p>","DOI":"10.13107\/jocr.2026.v16.i09.8078","type":"journal-article","created":{"date-parts":[[2026,9,8]],"date-time":"2026-09-08T08:22:15Z","timestamp":1788855735000},"page":"319-323","update-policy":"https:\/\/doi.org\/10.13107\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Three-Dimensional Surgical Planning and Patient-Specific Osteotomy Guide in the Management of Chronic Monteggia Fracture: A Case Report"],"prefix":"10.13107","volume":"16","author":[{"given":"Abhishet","family":"Varama","sequence":"first","affiliation":[{"name":"Department of Orthopedic Surgery, Faculty of Medicine, Chulalongkorn University, King Chulalongkorn Memorial Hospital, Bangkok, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chittawee","family":"Jiamton","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Queen Savang Vadhana Memorial Hospital, Chonburi, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Natthaphat","family":"Viriya","sequence":"additional","affiliation":[{"name":"Biomechanics Research Center, Chulalongkorn University, Bangkok, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chedtha","family":"Puncreobutr","sequence":"additional","affiliation":[{"name":"Department of Metallurgical Engineering, Faculty of Engineering, Chulalongkorn University, Bangkok, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Boonrat","family":"Lohwongwatana","sequence":"additional","affiliation":[{"name":"Department of Metallurgical Engineering, Faculty of Engineering, Chulalongkorn University, Bangkok, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"5271","published-online":{"date-parts":[[2026]]},"container-title":["Journal of Orthopaedic Case Reports"],"original-title":[],"deposited":{"date-parts":[[2026,9,13]],"date-time":"2026-09-13T08:45:23Z","timestamp":1789289123000},"score":1,"resource":{"primary":{"URL":"https:\/\/jocr.co.in\/wp\/2026\/09\/three-dimensional-surgical-planning-and-patient-specific-osteotomy-guide-in-the-management-of-chronic-monteggia-fracture-a-case-report\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026]]},"references-count":0,"journal-issue":{"issue":"9","published-online":{"date-parts":[[2026]]},"published-print":{"date-parts":[[2026]]}},"URL":"https:\/\/doi.org\/10.13107\/jocr.2026.v16.i09.8078","relation":{},"ISSN":["2321-3817"],"issn-type":[{"value":"2321-3817","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026]]},"assertion":[{"value":"Research Article","name":"content_type","label":"Content Type"},{"value":"Yes","name":"crosschecked","label":"CrossChecked"},{"value":"Yes","name":"peer_reviewed","label":"Peer Reviewed"},{"value":"10.13107\/jocr.2026.v16.i09.8078","name":"published","label":"Published"},{"value":"Creative Commons Attribution","name":"license","label":"License","explanation":{"URL":"https:\/\/creativecommons.org\/licenses\/by\/4.0"},"group":{"name":"rights","label":"Rights"}}]}}
