Three-dimensional Printing Technology and Role for Custom Implants in Orthopedic Oncology

Three-dimensional (3D) printing is an evolving technology that involves the sequential application of material to a flat surface to gradually build structures from the base up. This technique of "additive manufacturing" has a broad range of applications in the medical field and has significant potential to improve current clinical practice. Orthopedic surgery is at the forefront of these advancements and has incorporated the use of this technology in various ways. 3D-printed surgical applications include surgical planning, custom manufacturing of cutting guides and jigs, patient-matched implants, and 3D-printed biotechnology. This article introduces the current uses of 3D printing technology in orthopedic oncology, as well as the future potential for biological applications.
