Despite incomplete resection initially, this case represents an example for reconsidering salvage surgery in an interdisciplinary setting and center of expertise even for cases with residual tumor burden.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>LESSONS<\/jats:title>\n                    <jats:p>By highlighting the current literature and setting this clinical case in this context, the authors present a case with a 10-year long-term follow-up, showing that surgical salvage therapy is a possible treatment path with predictable surgery-related morbidity in patients with spinal chondrosarcomas.<\/jats:p>\n                    <jats:p>\n                      <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"uri\" xlink:href=\"https:\/\/thejns.org\/doi\/10.3171\/CASE25317\">https:\/\/thejns.org\/doi\/10.3171\/CASE25317<\/jats:ext-link>\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/case25317","type":"journal-article","created":{"date-parts":[[2025,9,1]],"date-time":"2025-09-01T23:49:18Z","timestamp":1756770558000},"source":"Crossref","is-referenced-by-count":0,"title":["Long-term follow-up after cervical en bloc resection as salvage surgery of spinal chondrosarcoma: illustrative case"],"prefix":"10.3171","volume":"10","author":[{"given":"Stefanie","family":"Ott","sequence":"first","affiliation":[{"name":"Department of Spine Surgery, Orthocentrum Hamburg, Hamburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Malte","family":"Schroeder","sequence":"additional","affiliation":[{"name":"Department of Trauma and Orthopaedic Surgery, University Medical Center Hamburg-Eppendorf, Hamburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karl-Heinz","family":"Frosch","sequence":"additional","affiliation":[{"name":"Department of Trauma and Orthopaedic Surgery, University Medical Center Hamburg-Eppendorf, Hamburg, Germany"},{"name":"Department of Trauma and Orthopaedic Surgery, BG Klinikum Hamburg, Hamburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nils","family":"Hansen-Algenstaedt","sequence":"additional","affiliation":[{"name":"Department of Spine Surgery, Orthocentrum Hamburg, Hamburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"issue":"8","key":"bib1","series-title":"Spine (Phila Pa 1976)","first-page":"678","article-title":"Surgical management of spinal chondrosarcomas","volume":"41","author":"Fisher","year":"2016","unstructured":"Fisher CGVersteeg ALDea NSurgical management of spinal chondrosarcomas.
