The Association of University Radiologists Radiology Research Alliance Task Force on three-dimensional (3D) printing presents a review of the logistic considerations for establishing a clinical service using this new technology, specifically focused on implications for radiology. Specific topics include printer selection for 3D printing, software selection, creating a 3D model for printing, providing a 3D printing service, research directions, and opportunities for radiologists to be involved in 3D printing. A thorough understanding of the technology and its capabilities is necessary as the field of 3D printing continues to grow. Radiologists are in the unique position to guide this emerging technology and its use in the clinical arena.

“…The surgeons were able to better understand the patient's anatomy, with the models resulting in an altered surgical plan or approach in some cases . Simulated surgery aided in instrument selection resulting in less need for adjustment intraoperatively as well as providing a better understanding of landmarks such as resection margins and screw placements . Surgeons commented that they felt the models were less useful for simple pathologies but could greatly improve understanding of more complex fractures and deformities …”

“…When analysing the subjective data regarding the benefits of 3D models, there is a consistent trend that surgeons found 3D models useful when dealing with complicated anatomy . 3D printed 1:1 scale models allowed surgeons to appreciate the structure and relations of the relevant anatomy much better than the visualization provided by two‐dimensional (2D) CT images conventionally used today.…”

Background Three‐dimensional (3D) printing has seen increasing interest in surgery, where it improves the visualization of difficult anatomy in complex cases. This literature review investigates the benefits and limitations of 3D printed models in preoperative planning in the field of orthopaedic surgery. Methods A literature search was performed using the Ovid platform on the Embase and MEDLINE databases using the terms ‘3D printing’, ‘Orthopaedics’ and ‘Surgical Planning’. Studies using 3D printed models as a part of preoperative planning were included. All others were excluded. Data regarding the metrics used to assess the benefit of the use of 3D models, surgical outcome, and surgeon or patient opinion on the technology were extracted. Results A total of 41 studies resulted. Eight (19.5%) were case–control studies, the remainder were case reports or case series. Assessment of benefit was mostly subjective, although the case–control studies included objective metrics such as operation time, intraoperative blood loss and intraoperative fluoroscopy time. The use of 3D printing technology showed subjective benefit for both patient and surgeon as well as indicating clinically significant improvements in intraoperative metrics. Conclusion Despite the current absence of large scale trials, 3D printing has clear benefits in preoperative planning, particularly when utilized in complex cases. A streamlined workflow for case selection, in‐house model creation and preoperative rehearsals is still required to be developed before the process is ready for routine use. Evidence supports an improvement in intraoperative metrics and patient engagement but data to support improved clinical outcome is lacking.

“…The gap errors along the surface contact of the assembled 3D-printed bone segments were measured and the maximum error was less than 2 mm; the discrepancy error should be as small as possible. A 3D-printed bone fracture with a different color on surface fracture area was printed using high-end full color 3D printer to imitate the realistic anatomy fracture (Bizzotto, et al, 2015) and (Bizzotto, et al, 2016). The 3D-printed bone offers 1:1 in scale as a reference in pre-surgery, so that the surgeon can observe the distribution of the fracture line in 3D space, which is usually difficult to achieve by using a computer 3D model.…”

The bone fragment and fracture lines may not clear enough to be visualized after bone reduction and may be hidden behind other bones. A 3D printing technology can be used to deal with this drawback. A series of algorithms were developed to ensure that two adjacent bone fragments fabricated can be assembled successfully. In this study, we developed a bone reduction algorithm, and a mesh-overlapping detection and removal algorithm to ensure that two 3D-printed fragments are easily assembled and disassembled. In addition, we also developed a method to detect and extract fracture boundary of two adjacent fragments, and then apply a multi-color 3D printing technology to fabricate the assembled bone fragments. The advantage of the proposed method is that we can show the status of 3D-printed bone fragments before and after bone reduction, with fracture lines printed in different color..
