Three-Dimensional Investigation by Computed Tomography of the Skeleton Manus in Van Cats

Abstract

This study aimed to obtain the three-dimensional (3D) reconstruction by computed tomography (CT) and the osteometric measurements of the skeleton manus (ossa carpi, ossa metacarpalia I-V ve ossa digitorum manus) in adults Van cats, and to determine the biometric differences between these measurement values in male and female cats. In the study, 16 adult Van cats (8 females, 8 males) were used. The cats that were anesthetized with the xylazine-ketamine combination were scanned by CT device, and images of skeleton manus were obtained. These axial images were transferred to the workstation for processing in DICOM format and then reconstruction was performed using Syngo CT, a 3D reconstruction program. The bones in three-dimensional reconstruction images were evaluated for their anatomical features. Volumetric and morphometric measurement values were obtained from these images and statistical analyzes were done. In the results of morphometric analyses, statistically significant differences (P<0.05) were seen between measured values of the carpal bones, metacarpal I-V bones and phalanges of the digits in male and female Van cats. The volumetric measurement values of the carpal bones, metacarpal I-V bones and phalanges of the digits were statistically significantly greater in male cats than in female cats (P<0.05). In conclusion, the carpal bones, metacarpal I-V bones and phalanges of the digits were evaluated volumetric, morphometric, and morphologically in Van cats. The biometric differences between the osteometric measurement values of these bones in both sexes were examined statistically. © 2020 Ataturk Universitesi. All rights reserved.
