“…One of the most important advantages of PSGs is the achievement of an accurate resection of bone tumors with safe margins [ 11 , 18 , 19 ]. From previous cadaver studies, manual resection can result in inaccuracies of up to 5–15 mm, which might lead to unexpected intralesional resection [ 20 , 21 , 22 , 23 ].…”

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.

“…Implants can not only focus on filling bone defects but attempt functional reconstruction. 53 Additional 3D printed implants on the skeleton include 3D printed polyetherketoneketone (PEKK) skull implants where no shaving is necessary as the implant is a customized design and fit. 52 There are also maxillofacial, spinal, and dental implants.…”

3D printing has been applied to multiple areas since 1980. Biomedical applications have grown significantly and become the mainstream of 3D printing applications. In this review, we elucidated the publication distribution of biomedical 3D printing using the CAS Content Collection. From 2010 to 2021, journal and patent publications grew steadily, except for the decline in patent publications in 2021. In general, journal publications are higher than patents. There are approximately 90 countries participating in the 3D printing application in this field. We are reporting the publication distributions related to the following categories: (1) four major techniques: powder bed fusion, extrusion, jetting, and photopolymerization; (2) substances: polymers and inorganic substances; (3) biomedical fields: tissue/organs, orthopedic/prosthetic, pharmaceutical, and others. We investigated the correlation between these search terms and revealed the co-occurrence of the concepts appearing in publications related to 3D printing in biomedical applications. This review provides an overview of the current advancement and trends of 3D printing applications in the biomedical area.

“…Among them, orthopedic oncology is the one using it most actively. Bones and their defects and tumors are modeled for surgical planning, personalized surgical tools for personalized surgical instruments, and implant manufacturing, which are currently the most typical applications [ 15 , 16 , 17 , 18 ].…”

The application of 3D printing in bone grafts is gaining in importance and is becoming more and more popular. The choice of the method has a direct impact on the preparation of the patient for surgery, the probability of rejection of the transplant, and many other complications. The aim of the article is to discuss methods of bone grafting and to compare these methods. This review of literature is based on a selective literature search of the PubMed and Web of Science databases from 2001 to 2022 using the search terms “bone graft”, “bone transplant”, and “3D printing”. In addition, we also reviewed non-medical literature related to materials used for 3D printing. There are several methods of bone grafting, such as a demineralized bone matrix, cancellous allograft, nonvascular cortical allograft, osteoarticular allograft, osteochondral allograft, vascularized allograft, and an autogenic transplant using a bone substitute. Currently, autogenous grafting, which involves removing the patient’s bone from an area of low aesthetic importance, is referred to as the gold standard. 3D printing enables using a variety of materials. 3D technology is being applied to bone tissue engineering much more often. It allows for the treatment of bone defects thanks to the creation of a porous scaffold with adequate mechanical strength and favorable macro- and microstructures. Bone tissue engineering is an innovative approach that can be used to repair multiple bone defects in the process of transplantation. In this process, biomaterials are a very important factor in supporting regenerative cells and the regeneration of tissue. We have years of research ahead of us; however, it is certain that 3D printing is the future of transplant medicine.
