Background: The present study aimed to differentiate between normal and dysplastic canine coxofemoral joints by assessing the corresponding bone specimens and digital X-rays moreover, our study provides a substitute teaching strategy using 3D-printed models of canine coxofemoral joints. This work was conducted on twenty-eight mixed breed dogs, sixteen dogs were used for bone preparation samples by boiling method, then these bones were scanned to create relatively identical 3D printed models. twelve dogs were anesthetized for the radiological study. An extended ventrodorsally radiograph of the coxofemoral joint was obtained to calculate the Norberg angle, Centre-edge angle, and dorsal acetabular femoral head coverage width and area indices. Results: The study's results illustrated the normal conformational anatomic criteria associated with healthy coxofemoral joints versus dysplastic joints in both bone specimens and 3D-printed models. In a normal joint, the coxofemoral articulation was congruent and smoothly margined with the acetabulum being deep and the femoral head being hemispherical. However, the dysplastic coxofemoral joint showed shallow acetabular fossa and a deformed, flattened femoral head with associated osseous proliferation and joint incongruity. The Norberg angle, Centre-edge angle, dorsal acetabular femoral head coverage width, and area indices differed significantly between normal and dysplastic joints. In normal coxofemoral joints, the mean ± (standard deviation) SD value of the Norberg angle was 115.5± 3.05 a, and the Centre-edge angle was 32.57± 3.54 a. The indices of dorsal acetabular femoral head coverage area and width were 52.94± 3.41 a, and 58.32± 5.33 arespectively. Conclusion: Finally, this work presented alternative teaching models (3d printing) that play an important role in the veterinary field and assist in the understanding of the normal structure and dysplastic state of canine coxofemoral joint. Also, some parameters were measured in x-rays of normal and dysplastic coxofemoral joint to detect hip dysplasia, which helps exclude the highly diseased dogs before breeding.

“…For example, using 3D‐printed models of an ovine stomach allowed students to gain a deeper understanding of the spatial structure of the stomach and its connection to the adjacent anatomical structure. This example represents a valuable and innovative teaching tool for the study of surface and topographical anatomy in veterinary medicine 18 . Furthermore, 3D scanning has been effectively used to generate skeletal models of the horse thoracic limb and bovine femur, which serve as valuable teaching aids for learning and practical application in the veterinary anatomy classes 19,20 .…”

Veterinary anatomy plays a crucial role in the curriculum for veterinary medicine and surgery. The integration of modern information technology in veterinary education can greatly benefit from innovative tools such as augmented reality (AR) applications. The aim of this study was to develop an accurate and interactive three‐dimensional (3D) digital model of an animal skull using AR technology, aiming to enhance the learning of skull anatomy in veterinary anatomy education. In this study, a canine skull specimen was isolated, and the skull bones were scanned using a structured light scanner to create a 3D digital model of the canine skull, which was found to be indistinguishable from the original specimen by measurement of skull proportions. Furthermore, the interactive AR model of the canine skull, displayed using Unity3D, was subjected to testing and evaluation by 60 first‐year veterinary medical students attending the gross anatomy of the animal. The students were divided into two groups: the traditional group and AR group. Both groups completed an objective test and a questionnaire. The evaluation of learning effectiveness in the test revealed no significant difference between the traditional group (which learned using textbooks and a canine skull specimen) and AR group (which learned using AR tools). However, in the questionnaire, students displayed high enthusiasm and interest in using the AR tool. Therefore, the application of AR tools can improve students' motivation for learning and enhance the comprehension of anatomical structures in three dimensions. Furthermore, this study exemplifies the use of AR as an auxiliary tool for teaching and learning in veterinary anatomy education.

“…They found no statistically significant difference between using 3D models and plastinated specimens for instruction considering the students' scores on a practical neuroanatomy exam [13]. Mendaza-DeCal and Rojo [14] developed a 3D printed model of an ovine stomach through a surface scanner for first year veterinary students to learn surface and topographical anatomy. They reported that the 3D printed ovine stomach model supported spatial visualization of anatomical relationships as a complement to a real stomach based on the students' assessments after studying both real and 3D printed model [14].…”

Three dimensional (3D) printing technology in veterinary anatomy education is an evolving area providing accurately, rapidly, and reproducibly anatomical specimens. In this study, 3D printed sheep brain models were produced using magnetic resonance imaging (MRI) scanning, and their effectiveness was compared with cadaveric materials by creating three groups from undergraduate veterinary students. The study was performed when veterinary anatomy lectures in Erciyes University were carried out via live fully online learning platforms in virtual classes like many other universities in the world due the Covid-19 pandemic. Participants were subjected to an approximately 30 minute online lecture on the external and internal anatomy of the sheep brain using cadaveric materials only (n=21, Group 1), 3D printed models only (n=20, Group 2), or a combination of cadaveric materials and 3D printed models (n=20, Group 3) as teaching aids. Online post-tests carried out following the online lectures showed no statistically significant difference between the scores of the groups. Furthermore, online questionnaires conducted after the post-tests demonstrated that 3D printed models helped students learn about sheep brain anatomy. The finding of this study suggests that 3D printed models can be considered as a supplement teaching resource to cadaveric materials in veterinary anatomy education particularly when students are supposed to learn more in a limited time regardless of whether or not the Covid-19 pandemic might end.
