A variety of skull shapes are frequently used for discrimination between animal species, breeds, and sexes. In this study, skulls of three different breeds of cats were examined by the geometric morphometric method, with the aim of revealing skull shape differences. For this purpose, 27 cats (6 British Shorthair, 7 Scottish Fold, and 14 Van cats) were used. The skulls of cats were modeled by computed tomography. Geometric morphometrics was applied using dorsal (8 landmarks, 63 semilandmarks) and lateral (8 landmarks, 63 semilandmarks) skull projections on these models. Centroid size differences between the breeds were statistically insignificant. However, the differences in shape were statistically significant for both the dorsal view and lateral view. Shape variation was less in the British Shorthair than in other breeds. Shape differences generally occurred around the orbit. In the skull of Scottish Folds, the orbit was situated more caudally than in other breeds. The British Shorthair had the largest orbital ring. In dorsal view, the Scottish Fold had the largest orbital diameter. The orbital ring of Van cats was smallest in both dorsal and lateral views. In the canonical variate analysis, it was seen that the breeds were separated from each other. The shape difference in the skull between different cat breeds could be revealed by geometric morphometrics. The results of this study provide useful information for taxonomy.
Pelvis is the bone roof formed by articulation of right and left coxae (os ilium, os ischii, os pubis) at the level of ventromedian (König et al., 2007;Özcan & Demiraslan, 2021). Linea terminalis is the imaginary line that separates the abdominal cavity and the pelvic cavity and extends along the line passed through the anatomical points called as ala sacralis, tuberculum musculus psoas minoris, eminentia ilio pubica, respectively. Thus, the limits of the entrance of the pelvic cavity are formed (Bahadir & Yildiz, 2016). The pelvis is the most important bone in terms of sex. Sex can be determined by looking at the formations and angles of the pelvis (Dursun, 2006). In the literature, there are studies in which pelvis measurements were made in terms of sex for different species. In studies, it was reported that the
Femoral fractures in cats are treated using pin and wires, lag screws, Rush pins, intramedullary threaded pins, interlocking pins, clamp rod internal fixators, and plates or plate-rods. In this study, 14 cats brought to the surgery clinic between the years 2010 and 2015 for fracture, due to either a road traffic accident or falling from a height, were evaluated. Following clinical and radiological examination of the cases, the type and location of the fracture, details of the applied fixation method, and postoperative clinical and radiological results were assessed. Localization of the fractures was as follows: 4 comminuted diaphyseal (1 segmental), 6 comminuted distal, and 4 uncomplicated distal transversal fractures. All fractures were closed. Following intramedullary positioning of the pins, rigid stabilization was observed in the fracture line. In the case of the segmental fracture, better stabilization was achieved when the medullary canal was completely filled. The patients were able to use their extremities 3-5 days after surgery and started walking normally from postoperative day 10. Functional healing was seen to improve gradually. Radiographic examination revealed sufficient calli to have formed between days 32 and 44. Complete healing and return to function with no complications was recorded in all the cases.
The patient in this case report was a male Golden Retriever dog, approximately 5 years of age, found in woodlands and presenting with an inability to use the right hindlimb. In craniocaudal and mediolateral radiographs taken of the patient, presence of an old comminuted fracture caused by a firearm injury was observed in the right femoral condyle. A custom-made trochlear groove of suitable dimensions for the patient was produced. The patient tip-toed on postoperative day 1 and was seen to be mostly weight-bearing by day 7. The lameness was determined to have lessened to a great extent after 1 month and at the end of 6 months it had completely disappeared. In control radiographs taken 1 year later, no osteoarthritis findings were observed in the knee joint.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
