“…showed that models demonstrated structural instability with initial surgeon selected screw placements which were then adjusted accordingly. Planning of osteotomies is another benefit of the models, allowing analysis of complex anatomy in 3D, providing improved precision and accuracy compared to 2D modalities . While the difference in the rate of complications is reported as statistically insignificant in all cases, it is important to note these small scale studies are not adequately powered, reinforcing the need for further large scale trials to be performed.…”

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.

Computerised surgical planning for forearm procedures that considers both soft and bony tissue, requires alignment of preoperatively acquired computed tomography (CT) and magnetic resonance (MR) images by image registration. Normalised mutual information (NMI) registration techniques have been researched to improve efficiency and to eliminate the user dependency associated with manual alignment. While successfully applied in various medical fields, application of NMI registration to images of the forearm, for which the relative pose of the radius and ulna likely differs between CT and MR acquisitions, is yet to be described. To enable the alignment of CT and MR forearm data, we propose an NMI-based registration pipeline, which allows manual steering of the registration algorithm to the desired image subregion and is, thus, applicable to the forearm. Successive automated registration is proposed to enable planning incorporating multiple target anatomical structures such as the radius and ulna. With respect to gold-standard manual registration, the proposed registration methodology achieved mean accuracies of 0.08 ± 0.09 mm (0.01 -0.41 mm range) in comparison to 0.28 ± 0.23 mm (0.03 -0.99 mm range) associated with a landmark-based registration when tested on 40 patient datasets. Application of the proposed registration pipeline required less than 10 minutes on average compared to 20 minutes required by the landmark-based registration. The clinical feasibility and relevance of the method were tested on two different clinical applications, a forearm tumour resection and radioulnar joint instability analysis, obtaining accurate and robust CT-MR image alignment for both cases.

Corrective Osteotomy of Malunited Diaphyseal Fractures of the Forearm Simplified Using 3-Dimensional CT Data: Proposal of Our Simple Strategy Through Case Presentation

Abstract: We postulated that our simple preoperative simulation and manual osteotomy with the aid of 3D CT reconstruction and 3D real full-scale bone model fit in the clinical practice as a recent trend.
