Abstract: Chondrosarcoma is a malignant bone tumor with a high risk of local recurrence and distant metastasis, particularly to the lungs. Its management poses significant surgical challenges, especially in cases with multiple recurrences and the need for complex reconstructions. These situations demand highly individualized approaches and are associated with a high risk of complications, particularly infection. Achieving both oncological control and functional restoration is essential. This case report describes a patient who underwent hemipelvectomy with reconstruction using patient-specific, custom-made prosthesis created through three-dimensional printing technology. During mid-term follow-up, the patient presented broken sacral screws and the required revision included a new custom-made prosthesis with spinopelvic fixation. The integration of advanced imaging and three-dimensional printing has marked a significant milestone in orthopedic oncology, enabling precise, anatomically matched implants. These porous, custom-designed prostheses improve biological integration and allow optimal load distribution, contributing to better functional outcomes and complication control, even in the setting of revision surgeries. The spinopelvic fixation for hemipelvectomy reconstructions and the advantages of the pelvic ring reconstruction are questions to answer in the near future in order to optimize these patients’ treatment and functional outcomes.
