Evaluation of sex differences in pelvis and femur x‐ray images in British shorthair cats by geometric morphometric method

Abstract

AbstractThe study covers British Shorthair cats, which is a popular domestic cat breed in our country and defined as ‘brachycephalic’ in terms of skull structure. Article focuses on the pelvis and femur region of cats which gynaecological and orthopaedic diseases of this cat breed, which are frequently encountered in clinical practice, is found to be important. It is aimed to reveal the shape differences between male and female individuals using geometric morphometric method. X‐ray images were used to examine the pelvis and femurs of cats via geometric method. Radiological images were obtained from a total of 40 British Shorthair cats (20 females and 20 males) in two positions, ventro‐dorsal (VD) and latero‐lateral (LL), and shape differences between the sexes were examined. As result, it is seen that the measurement points taken from the males are more outward and have sharper angles than the females. Study also shows pelvis is a better choice than femur when it comes to sex discrimination. Although traditional morphometric methods are more useful in clinical practice, it is thought that is important to support or re‐evaluate the data with the geometric morphometric method in academic field for a further approach.
