With this emerging opportunity arises a necessity to undertake a thorough assessment of the manufactured tools employed in clinical practice. The objectives of this article are to describe the pathway of in-house printing and evaluate the accuracy of 3D-printed specific instruments.\n\nCase Report: A case is reported along with the workflow for creating a patient model and cutting guide. The patient is a 76-year-old Caucasian woman with bone metastasis from a known renal cancer located in the pelvis. The model was used preoperatively, while the guide was used during surgery. Following this, the guide underwent computed tomography (CT) scanning, and a 3D digital model was reconstructed. Two dimensions, labeled A and B, were established. We compared pre-operative measurements, respectively, with measurements from the printed physical guide and from the rescanned post-operative digital model. Finally, A and B were measured on the bone defect on the patient\u2019s post-operative CT. Variation in axis A value between the mean of the first two groups was 0.5 mm and in axis B was 0.7 mm. On the printed physical guide, the mean of axis A was 73.5 mm, and the mean of axis B was 71.8 mm. Variation in A value between the mean of this group and the pre-operative was 1.7 mm and in B value was 0.5 mm.\n\nConclusion: The workflow used at our hospital was described with an example of how to evaluate the accuracy of in-house 3D printing. Results showed high accuracy of the printing method, a reliable correlation between desired and actual outcomes, and a short lead time.\n\nKeywords: 3D printing, cutting guide, in-house printing.<\/jats:p>","DOI":"10.13107\/jocr.2025.v15.i01.5142","type":"journal-article","created":{"date-parts":[[2025,1,8]],"date-time":"2025-01-08T16:31:46Z","timestamp":1736353906000},"page":"103-108","source":"Crossref","is-referenced-by-count":2,"title":["3D-Printed Cutting Guide in Oncological Pelvic Surgery: A Case Report and Proof of Concept Validation of Cutting Guide Accuracy"],"prefix":"10.13107","volume":"15","author":[{"name":"Department of Orthopaedic Oncology, Aarhus University Hospital, Aarhus N, Denmark","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna Bertoli","family":"Borgognoni","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arne Oliver","family":"L\u00fccke","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Department of Radiology, Aarhus University Hospital, Aarhus N, Denmark,","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katerina","family":"Znacko","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Department of Orthopaedic Surgery, Zealand University Hospital, Aarhus N, Denmark,","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karen Eich","family":"Hammer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Department of Innovation and International Affairs, Aarhus University Hospital, Aarhus N, Denmark.","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Baad-Hansen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Department of Orthopaedic Oncology, Aarhus University Hospital, Aarhus N, Denmark","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"5271","published-online":{"date-parts":[[2025]]},"container-title":["Journal of Orthopaedic Case Reports"],"original-title":[],"deposited":{"date-parts":[[2025,1,8]],"date-time":"2025-01-08T16:31:51Z","timestamp":1736353911000},"score":1,"resource":{"primary":{"URL":"https:\/\/jocr.co.in\/wp\/2025\/01\/01\/3d-printed-cutting-guide-in-oncological-pelvic-surgery-a-case-report-and-proof-of-concept-validation-of-cutting-guide-accuracy\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2025]]},"published-print":{"date-parts":[[2025]]}},"URL":"https:\/\/doi.org\/10.13107\/jocr.2025.v15.i01.5142","relation":{},"ISSN":["2321-3817"],"issn-type":[{"value":"2321-3817","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025]]}}}
