“…Rapid prototyping is a relatively new technique to the medical and veterinary industries, primarily being used to produce bespoke surgical implants (Ciocca et al, ; Frame and Huntley ; Galamatucci et al, ; Kuipers von Lande et al, ). In the first step a stack of cross‐section images is converted into a virtual 3D, which is then used to cut the corresponding physical model from a block of material using laser cutting technology.…”

“…Its application varies widely from bespoke surgical implants, advanced surgical approach training, to basic anatomy teaching models. Despite its widespread use in the medical sciences, use by the veterinary profession is largely limited to bespoke surgical implants (Kuipers von Lande et al, ), and has not been widely used to create veterinary anatomical models.…”

Three-dimensional (3D) information plays an important part in medical and veterinary education. Appreciating complex 3D spatial relationships requires a strong foundational understanding of anatomy and mental 3D visualization skills. Novel learning resources have been introduced to anatomy training to achieve this. Objective evaluation of their comparative efficacies remains scarce in the literature. This study developed and evaluated the use of a physical model in demonstrating the complex spatial relationships of the equine foot. It was hypothesized that the newly developed physical model would be more effective for students to learn magnetic resonance imaging (MRI) anatomy of the foot than textbooks or computer-based 3D models. Third year veterinary medicine students were randomly assigned to one of three teaching aid groups (physical model; textbooks; 3D computer model). The comparative efficacies of the three teaching aids were assessed through students' abilities to identify anatomical structures on MR images. Overall mean MRI assessment scores were significantly higher in students utilizing the physical model (86.39%) compared with students using textbooks (62.61%) and the 3D computer model (63.68%) (P < 0.001), with no significant difference between the textbook and 3D computer model groups (P = 0.685). Student feedback was also more positive in the physical model group compared with both the textbook and 3D computer model groups. Our results suggest that physical models may hold a significant advantage over alternative learning resources in enhancing visuospatial and 3D understanding of complex anatomical architecture, and that 3D computer models have significant limitations with regards to 3D learning.

“…The use of this technology reduces surgery time, speeds healing, and improves clinical outcome [6,8,9]. In veterinary medicine, reports of additive manufacturing in surgery are limited to case reports or experimental studies, including the creation of a customized surgical plate for canine tibial plateau leveling osteotomy, correction of a persistent hard palate defect, the production of titanium mesh cages and plates (imbued with repair stimulating substances) to repair canine radial defects, and most recently a feline titanium mandibular prosthesis [9][10][11][12]. The timeline associated with each study were either not reported or had a greater than 4-week turnaround from diagnosis until surgery [9][10][11][12].…”

Schedule feasibility and workflow for additive manufacturing of titanium plates for cranioplasty in canine skull tumors

et al. 2020

Background: Additive manufacturing has allowed for the creation of a patient-specific custom solution that can resolve many of the limitations previously reported for canine cranioplasty. The purpose of this pilot study was to determine the schedule feasibility and workflow in manufacturing patient-specific titanium implants for canines undergoing cranioplasty immediately following craniectomy. Results: Computed tomography scans from patients with tumors of the skull were considered and 3 cases were selected. Images were imported into a DICOM image processing software and tumor margins were determined based on agreement between a board-certified veterinary radiologist and veterinary surgical oncologist. Virtual surgical planning was performed and a bone safety margin was selected. A defect was created to simulate the planned intraoperative defect. Stereolithography format files of the skulls were then imported into a plate design software. In collaboration with a medical solution centre, a custom titanium plate was designed with the input of an applications engineer and veterinary surgery oncologist. Plates were printed in titanium and post-processed at the solution centre. Total planning time was approximately 2 h with a manufacturing time of 2 weeks. Conclusions: Based on the findings of this study, with access to an advanced 3D metal printing medical solution centre that can provide advanced software and printing, patient-specific additive manufactured titanium implants can be planned, created, processed, shipped and sterilized for patient use within a 3-week turnaround.

“…Recently, 3D-printed osteotomy guides have been used for malignant bone tumor surgeries, resulting in precise resection of the tumor and implantation, reduced blood loss, and reduced operation time (18,32,34). 3D-printed implants have been used to reconstruct bone defects in complex structures such as the maxilla and cranium (17,28).…”

Cranioplasty for Multilobular Osteochondrosarcoma Using 3-Dimensional Printing Technology in Dogs: A Report of Two Cases with a Long-Term Follow-Up

et al. 2022

Multilobular osteochondrosarcoma (MLO) reportedly has a good prognosis after complete resection. This study reports the successful treatment of MLO in two dogs using 3-dimensional (3D) printing technology. A nine-yearold castrated male Maltese (Case 1) and a five-year-old castrated male poodle (Case 2) both presented with a mass in the skull. Diagnostic imaging revealed a cranial mass arising from the cranio-orbital and parieto-occipital bones. The masses were resected using 3D-printed osteotomy guides, and the resulting defects were reconstructed using 3D-printed patient-specific implants. Histopathological results confirmed the resection of MLOs with clean margins. Patients routinely recover from surgery without complications. To date, the two patients remain alive without clinical signs of tumor recurrence at 20 and 12 months postoperatively, respectively. In the management of MLO in dogs, 3D printing technology can allow accurate tumor resection, reduced surgical time, and successful reconstruction of large defects.
