In early stages, curettage is preferred, but in case of local recurrence or voluminous lesions in the periacetabular region, wide resection and reconstruction are recommended. The purpose of this article is to increase clinicians\u2019 awareness of the importance of the follow-up of these patients and to describe a case of a voluminous recurrence of a giant-cell tumour in the pelvis. We present a 25-year-old female who underwent internal hemipelvectomy assisted by 3D cutting-guides and reconstruction with a custom-made 3D-printed pelvic prosthesis, hip arthroplasty and ilio-sacral arthrodesis. No postoperative complications occurred and, at long-term follow-up, the patient had a stable and painless hip joint, good bone-implant osteointegration, with an excellent functional outcome. In spite of all available reconstructive techniques, in well-selected patients with voluminous pelvic resections, custom-made 3D-printed implants allow patients to have a good mechanical outcome.<\/jats:p>","DOI":"10.3390\/diagnostics13030485","type":"journal-article","created":{"date-parts":[[2023,1,30]],"date-time":"2023-01-30T08:28:23Z","timestamp":1675067303000},"page":"485","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Custom-Made 3D-Printed Prosthesis after Resection of a Voluminous Giant Cell Tumour Recurrence in Pelvis"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2089-4876","authenticated-orcid":false,"given":"Adyb-Adrian","family":"KHAL","sequence":"first","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Iuliu Hatieganu University of Medicine and Pharmacy, 400000 Cluj-Napoca, Romania"},{"name":"Department of Paediatric Orthopaedics, AP-HM Timone Enfants, 13005 Marseille, France"},{"name":"Regina Maria Private Health Care Network, 400117 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9046-9432","authenticated-orcid":false,"given":"Dragos","family":"APOSTU","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Iuliu Hatieganu University of Medicine and Pharmacy, 400000 Cluj-Napoca, Romania"},{"name":"Regina Maria Private Health Care Network, 400117 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Calin","family":"SCHIAU","sequence":"additional","affiliation":[{"name":"Regina Maria Private Health Care Network, 400117 Cluj-Napoca, Romania"},{"name":"Department of Radiology, Iuliu Hatieganu University of Medicine and Pharmacy, 400000 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7531-6075","authenticated-orcid":false,"given":"Nona","family":"BEJINARIU","sequence":"additional","affiliation":[{"name":"Regina Maria Private Health Care Network, 400117 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2230-2811","authenticated-orcid":false,"given":"Sebastien","family":"PESENTI","sequence":"additional","affiliation":[{"name":"Department of Paediatric Orthopaedics, AP-HM Timone Enfants, 13005 Marseille, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean-Luc","family":"JOUVE","sequence":"additional","affiliation":[{"name":"Department of Paediatric Orthopaedics, AP-HM Timone Enfants, 13005 Marseille, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,29]]},"reference":[{"key":"ref_1","unstructured":"Manfrini, M.
