Methods: The surgical treatment of a huge multi-level chordoma of the thoracic spine with unusual extension is reported. Anteriorly, the tumor widely invaded the mediastinum and displaced the aorta; on the left side, it expanded in the subpleuric region; posteriorly, it was uncommonly distant 13 mm from the posterior wall. Results: EnBloc resection is largely performed for primary bone tumors of the spine and many reports have been published concerning brilliant solutions to difficult issues of surgical anatomy. One of the major challenges is still the compatibility between oncological and functional requirements. Conclusions: Oncological staging, careful imaging analysis, a multidisciplinary surgical team, and utilization of the most recent technologies like navigation and robotics have made an oncologically appropriate EnBloc resection of a multi-level chordoma of the thoracic spine possible without affecting the continuity of the spinal canal and without any involvement of its content by an original \u201cL\u201d-shaped osteotomy.<\/jats:p>","DOI":"10.3390\/jcm14020349","type":"journal-article","created":{"date-parts":[[2025,1,8]],"date-time":"2025-01-08T11:56:22Z","timestamp":1736337382000},"page":"349","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["EnBloc Resection of a Chordoma of the Thoracic Spine by \u201cL\u201d-Shaped Osteotomy for Spinal Canal Preservation"],"prefix":"10.3390","volume":"14","author":[{"given":"Alessandro","family":"Gasbarrini","sequence":"first","affiliation":[{"name":"Spine Surgery Department, IRCCS Istituto Ortopedico Rizzoli, 40136 Bologna, Italy"},{"name":"Department of Biomedical and Neuromotor Sciences, Alma Mater Studiorum University of Bologna, 40126 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5831-5430","authenticated-orcid":false,"given":"Stefano","family":"Pasini","sequence":"additional","affiliation":[{"name":"Spine Surgery Department, IRCCS Istituto Ortopedico Rizzoli, 40136 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhaozong","family":"Fu","sequence":"additional","affiliation":[{"name":"Department of Spine Surgery, Jiangmen Central Hospital, Jiangmen 529030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Riccardo","family":"Ghermandi","sequence":"additional","affiliation":[{"name":"Spine Surgery Department, IRCCS Istituto Ortopedico Rizzoli, 40136 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Valerio","family":"Pipola","sequence":"additional","affiliation":[{"name":"Spine Surgery Department, IRCCS Istituto Ortopedico Rizzoli, 40136 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mauro","family":"Gargiulo","sequence":"additional","affiliation":[{"name":"Vascular Surgery Department, IRCCS Policlinico di Sant\u2019Orsola, 40138 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marco","family":"Innocenti","sequence":"additional","affiliation":[{"name":"Orthoplasty Department, IRCCS Istituto Ortopedico Rizzoli, 40136 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stefano","family":"Boriani","sequence":"additional","affiliation":[{"name":"Alma Mater Studiorum University of Bologna, 40126 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"106","DOI":"10.1097\/00003086-198011000-00013","article-title":"A system for the surgical staging of musculoskeletal neoplasms","volume":"153","author":"Enneking","year":"1980","journal-title":"Clin.
