    Assessing Thoracic Symmetry in Dogs
    (University of Agriculture, 2024) Mutlu, Zihni; Altundag, Yusuf; Güzel, Bariş Can
    This study aimed to conduct a detailed statistical shape analysis of the thorax across various dog breeds, focusing on the identification and characterization of shape variations and asymmetrical features. For this purpose, 3D images of 39 thoracic samples were collected from various regions across Türkiye, ensuring a diverse representation of breeds and populations. In the analysis, 136 specific anatomical landmarks were meticulously identified and marked from a lateral view of the thorax for each sample. The study revealed that the first principal component explained 28.89% of the total variation in directional asymmetry, suggesting consistent size or shape differences on one side of the thorax. Additionally, it was found that the first principal component explained 27.82% of the total variation in fluctuating facet asymmetry occurs if one region is consistently greater or has a different shape compared to the opposite and indicates underlying genetic or functional differences. This study highlights the usefulness of geometric morphometric analysis in distinguishing thoracic shape differences among various dog breeds, providing insights into their morphological diversity. Moreover, the findings underscore the potential of geometric morphometric analysis for taxonomic purposes, enabling more precise classification and understanding of breed-specific characteristics. This approach can aid in identifying subtle morphological variations that may be linked to breed history, function, or environmental adaptation. © 2024 University of Agriculture. All rights reserved.

    Evaluation of Clinical Outcomes of Cementless Porous Structured Total Hip Prosthesis in Dogs
    (University of Agriculture, 2024) Mutlu, Zihni; Hristov, Svetoslav Stoyanov; Bektas, Ceren Nur Giray; Bilgic, Eylem Bektas; Altunda?, Yusuf
    In this study, total hip replacement (THR) was performed by using implants from the Innoplant company on 30 dogs and 33 cases. The average weight of the dogs was 33.05 ± 11.15, and their age range was approx. 26.6 months. The breed distribution among the cases was: Golden Retriever (n=5), German Shepherd (n=2), Rottweiler (n=4), Kangal (n=3), Labrador Retriever (n=5), Mixed Breed (n=4), Alabay (n=1), Chow Chow (n=1), Border Collie (n=2), Samoyed (n=1), and Bulgarian Shepherd (n=2). About 57% of the cases had bilateral hip dysplasia, 37% had coxarthrosis, 3% had hip luxation, and 3% had excisional arthroplasty findings. In our study, both porous and non-porous screw cups and stems of the Innoplant brand were used, while complications occurred in 10 cases. Two of these complications happened during the operation, while 8 occurred after the operation. Of these complications, 9 were classified as major, and 1 was classified as minor. The complications observed including femoral fractures (n=2), stem subsidence (n=3), stem loosening (n=1), cup loosening (n=2), cup dislocation (n=1), and loosening in both the stem and the cup (n=1). In 4 of these cases, the prosthesis was completely removed, while revision surgery was performed in 6 dogs. The long-term results of the 6 revised cases were evaluated as very good. The time until the patients could place their foot on the ground after the operation was 24 hours for 11 cases and 36 hours for 20 cases. In conclusion, the cementless Innoplant prosthesis system used for THR, is a viable prosthetic technique with a low complication rate which provides successful clinical and radiographic outcomes over an average period of 31 months. © 2024 University of Agriculture.
