Geometrik Morfometri Yöntemi Kullanılarak Atlarda Os Coxae’larının İncelenmesi

Geometrik morfometri, normal morfometrik ölçümlerin aksine 2D düzlemde belirtilen noktaların x-y koordinatlarındaki farklılıkları ve varyasyonları açıklayan bir yöntemdir. Resim veya röntgen gibi iki boyutlu örnekler kullanılır. Bu çalışmada erişkin 23 (12 erkek, 11 dişi) tane atın sağ os coxae’sı geometrik olarak incelenmesi amaçlanmıştır. Her örnekten 120 santimetre uzaklıktan fotoğraflar alınmış ve bu örnekler üzerinden işaretlemeler yapılmıştır. Os coxae üzerinde 13 adet belirleyici nokta kullanılmıştır. Cinsiyet ayırımı bakımından, spina ischiadica’nın orta noktası ve ilium gövdesinin en dar bölümünün medial uç noktası arasında istatistiksel olarak anlamlı bir fark bulunmuştur (P

Investigation of Os Coxae in Horses Using Geometric Morphometry Method

In contrast to normal morphometric measurements, geometric morphometry is a method that can explain the differences and variations on the x-y coordinates of the specified points on a 2D plane. In this method, two-dimensional samples, such as pictures or x-rays, are used. The study aims to investigate the right os coxae of 23 adults (12 males, 11 females) horses geometrically. Photographs were taken from each sample at 120 centimeters distance and landmarks were made on these samples. 13 determining landmarks were used on os coxae. Medial endpoint of the narrowest section of the body of ilium and medial endpoint of ischial spine points were found to be statistically significant in terms of female and male distinction (P
