Orthopedic oncology has begun to use three-dimensional-printing technology, which is expected to improve the accuracy of osteotomies, ensure a safe margin, and facilitate precise surgery. However, several difficulties should be considered. Cadaver and clinical studies have reported more accurate osteotomies for bone-tumor resection using patient-specific cutting guides, especially in challenging areas such as the sacrum and pelvis, compared to manual osteotomies. Patient-specific cutting guides can help surgeons achieve resection with negative margins and reduce blood loss and operating time. Furthermore, this patient-specific cutting guide could be combined with more precise reconstruction using patient-specific implants or massive bone allografts. This review provides an overview of the basic technologies used in the production of patient-specific cutting guides and discusses their current status, advantages, and limitations. Moreover, we summarize cadaveric and clinical studies on the use of these guides in orthopedic oncology.
骨科肿瘤学开始使用三维打印技术，这有望提高截骨的准确性，确保安全边界，并便于精确手术。但是，应该考虑到几个难点。与手工截骨相比，尸体和临床研究报告称，使用患者特异性切割导板进行骨肿瘤切除的截骨更精确，特别是在骶骨和骨盆等具有挑战性的区域。患者特异性切割导板可以帮助外科医生实现阴性切缘的切除，并减少失血量和手术时间。此外，这种患者特异性切割导板可以与使用患者特异性植入物或大段同种异体骨进行的更精确的重建相结合。这篇综述介绍了用于制作患者特异性切割导板的基本技术，并讨论了它们的现状、优势和局限性。此外，我们总结了这些导板在骨科肿瘤学中的应用的尸体和临床研究。
