This case report describes the innovative creation of an anatomical calcaneum using a 3D printer. A patient presented with a recurrent aggressive stage of calcaneal giant cell tumor, which necessitated a complete resection, leaving a large void that required reconstruction. This paper outlines the 3D printing methodology used from pre-operative printing of the prototype, through the surgical procedure, to post-operative care. 3D images of the calcaneum were extracted from a CT scan and edited using 3D modelling software to print a hollow-shelled calcaneum. The printed prototype was created in two halves and sent for gas sterilization. After resecting the diseased calcaneum, the mold was filled with bone cement and clasped together with a proline mesh in between, for soft tissue attachment. Once the cement set, the shell was removed, and the shaped bone cement calcaneum was implanted into the patient with screws. The surrounding soft tissues and Achilles tendon were sutured to the mesh. Post-operatively, the patient was kept in a plaster dorsal slab for six weeks to allow for soft tissue incorporation. Six weeks after surgery, the patient began weight-bearing activities with an aesthetically shaped foot. This method for bone reconstruction is efficient, economical, and reproducible.<\/jats:p>","DOI":"10.1055\/s-0045-1809420","type":"journal-article","created":{"date-parts":[[2025,7,2]],"date-time":"2025-07-02T00:43:21Z","timestamp":1751417001000},"page":"001-008","source":"Crossref","is-referenced-by-count":0,"title":["A Novel Invention of a 3D Printed Mould for Calcaneum Replacement Post Total Calcanectomy for a Recurrent Aggressive GCT of the Calcaneum"],"prefix":"10.1055","volume":"60","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1499-8679","authenticated-orcid":false,"given":"Goh Boay Heong","family":"Eyrique","sequence":"additional","affiliation":[{"name":"Orthopedic Oncology Unit, Orthopedic and Traumatology Hospital Queen Elizabeth I and II Sabah, Kuala Lumpur, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5877-9905","authenticated-orcid":false,"given":"Tee Kok","family":"Keat","sequence":"additional","affiliation":[{"name":"Orthopedic Oncology Unit, Orthopedic and Traumatology Hospital Queen Elizabeth I and II Sabah, Kuala Lumpur, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aaron Gerarde","family":"Paul","sequence":"additional","affiliation":[{"name":"Orthopedic Oncology Unit, Orthopedic and Traumatology Hospital Queen Elizabeth I and II Sabah, Kuala Lumpur, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2025,7,1]]},"reference":[{"issue":"04","key":"ref1","first-page":"00230","article-title":"Three-dimensional Printing in Orthopaedic Surgery: Current Applications and Future Developments","volume":"5","author":"C M Wixted","year":"2021","journal-title":"J Am Acad Orthop Surg Glob Res Rev"},{"key":"ref2","doi-asserted-by":"crossref","first-page":"7940242","DOI":"10.1155\/2021\/7940242","article-title":"Preoperative Planning Using 3D Printing Technology in Orthopedic Surgery","volume":"2021","author":"D G Alemayehu","year":"2021","journal-title":"BioMed Res Int"},{"issue":"03","key":"ref3","doi-asserted-by":"crossref","first-page":"647","DOI":"10.2214\/AJR.11.7286","article-title":"Imaging of limb salvage surgery","volume":"198","author":"J Fritz","year":"2012","journal-title":"AJR Am J Roentgenol"},{"issue":"03","key":"ref5","doi-asserted-by":"crossref","first-page":"635","DOI":"10.1002\/ijc.33570","article-title":"Novel imaging techniques for intraoperative margin assessment in surgical oncology: A systematic review","volume":"149","author":"J Heidkamp","year":"2021","journal-title":"Int J Cancer"},{"issue":"51","key":"ref6","doi-asserted-by":"crossref","first-page":"e31578","DOI":"10.1097\/MD.0000000000031578","article-title":"Limb salvage surgery for calcaneal chondrosarcoma: A case report","volume":"101","author":"J Wang","year":"2022","journal-title":"Medicine (Baltimore)"},{"issue":"02","key":"ref7","doi-asserted-by":"crossref","first-page":"201","DOI":"10.1007\/s12306-024-00815-3","article-title":"The Musculoskeletal Tumor Society Scoring system is a valid subjective and objective tool to evaluate outcomes of surgical treatment of patients affected by upper and lower extremity tumors","volume":"108","author":"A Rizzo","year":"2024","journal-title":"Musculoskelet Surg"},{"issue":"02","key":"ref8","doi-asserted-by":"crossref","first-page":"187","DOI":"10.1007\/s003300050132","article-title":"Rapid prototyping (stereolithography) in the management of intra-articular calcaneal fractures","volume":"7","author":"G M Kacl","year":"1997","journal-title":"Eur Radiol"},{"issue":"03","key":"ref9","doi-asserted-by":"crossref","first-page":"100051","DOI":"10.1016\/j.fastrc.2021.100051","article-title":"Novel Utilization of 3D Printing Technology for a Chronic Malunited Calcaneum Fracture- A Case Report","volume":"1","author":"J Y Lee","year":"2021","journal-title":"Foot & Ankle Surgery Techniques, Reports & Cases"}],"container-title":["Revista Brasileira de Ortopedia"],"original-title":[],"language":"pt","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/s-0045-1809420.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,7,2]],"date-time":"2025-07-02T00:43:24Z","timestamp":1751417004000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/s-0045-1809420"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,4]]},"references-count":8,"journal-issue":{"issue":"02","published-online":{"date-parts":[[2025,6,14]]},"published-print":{"date-parts":[[2025,4]]}},"alternative-id":["s00451809420"],"URL":"https:\/\/doi.org\/10.1055\/s-0045-1809420","archive":["Portico","CLOCKSS"],"relation":{},"ISSN":["0102-3616","1982-4378"],"issn-type":[{"value":"0102-3616","type":"print"},{"value":"1982-4378","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,4]]}}}
