“…Guides serve two purposes intraoperatively: improving resection precision and fashioning a reciprocal allograft or metal implant for reconstruction. Patient-specific guides have demonstrated improved resection accuracy, high rates of R0 resection, and lower rates of LR at short-term followup [90][91][92][93] . These guides also have the potential to decrease operative time by allowing for a more preplanned resection technique in the context of complex and distorted anatomy.…”

» Negative margin resection of musculoskeletal sarcomas is associated with reduced risk of local recurrence.» There is limited evidence to support an absolute margin width of soft tissue or bone that correlates with reduced risk of local recurrence.» Factors intrinsic to the tumor, including histologic subtype, grade, growth pattern and neurovascular involvement impact margin status and local recurrence, and should be considered when evaluating a patient's individual risk after positive margins.» Appropriate use of adjuvant therapy, critical analysis of preoperative advanced cross-sectional imaging, and the involvement of a multidisciplinary team are essential to obtain negative margins when resecting sarcomas.

“…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 ]. A PSG can be applied for the preparation of massive bone allografts (MBAs) for the reconstruction of bone defects following bone-tumor resection ( Figure 1 ) [ 24 ]. A PSG can help surgeons achieve a more precise cutting of the MBA using the same predefined section planes for the resection of bone tumors [ 24 ].…”

“…With a better and more accurate understanding of anatomy, surgeons are confident in maintaining a safe surgical margin without compromising important structures [ 33 ]. The educational approach, when combined with the 3D model and the PSG, enables precise control of safe margins by demonstrating osteotomies with oscillating blades in the predefined resection planes to young surgeons [ 24 ].…”

“…They reported that all patients had negative margins, with a minimum distance of 2.5 mm between the achieved osteotomies and the tumor boundary; the mean cutting error was 0.8 mm [ 10 ]. Furthermore, Evrard et al analyzed the correlation between planned and obtained margins (excellent correlation, R 2 = 0.841; p < 0.0001) from the bone-tumor resections in various locations (n = 31) [ 24 ].…”

Current Concepts in the Resection of Bone Tumors Using a Patient-Specific Three-Dimensional Printed Cutting Guide

et al. 2023

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.

Musculoskeletal oncology involves rare diseases. As a result, there is a paucity of literature to guide practitioners. Studies are often clinical experience, retrospective reviews, noncomparative studies, and involve small numbers of patients. However, technological advances consistently arise in this field. This article represents the Musculoskeletal Tumor Society efforts to improve multispecialty collaboration and research credibility. It involves brief systematic reviews of novel ideas and suggests high‐quality research needed to provide and standardize best practices within this field.
