Türk Van Kedilerinde Kalça Kemiklerinin (Ossa coxae) Bilgisayarlı Tomografi Tabanlı Morfometrik Analizi

Bu çalışma Van kedilerinde ossa coxae’nin bilgisayarlı tomografi (BT) ile elde edilen görüntülerinin üç boyutlu (3B) modellemesini yapmak, osteometrik ölçüm değerlerini belirlemek amacıyla yapıldı. Çalışmada 16 adet (8 erkek, 8 dişi) erişkin Van kedisi kullanıldı. Öncelikle ketamin HCl - xylazin HCl kombinasyonu ile anesteziye alınan kediler, 16 kesit çok sıralı BT cihazı (Somatom Sensation 16; Siemens Medical Solutions, Erlangen, Germany) ile taranarak görüntüleri elde edildi. Daha sonra, her kedinin ossa coxae’sine ait tarama görüntüleri MIMICS 20.1 (The Materialise Group, Leuven, Belgium) programı yardımıyla üç boyutlu yapıya dönüştürülerek, morfometrik (12 doğrusal), hacim ve yüzey alanı ölçümleri alındı ve istatistiki analizi yapıldı. Ossa coxae’ya ait 14 adet ölçüm parametresinden 12 ölçüm parametresinin erkek kedilerde dişilere göre daha yüksek olduğu belirlendi. Osteometrik analiz sonuçlarına bakıldığında, bir yarımın en büyük uzunluğu (GL), acetabulum’un iç kenarlarının uzunluğu (LA), tuber ischiadicum’ların karşıdan karşıya maximum genişliği (GBTi) ve corpus ossis ischii’lerin karşıdan karşıya minumum genişliği (SBI) ölçüm değerlerinin erkek kedilerde dişi kedilere göre istatistik olarak anlamlı bir şekilde yüksek olduğu gözlendi (P

Computed Tomography-Based Morphometric Analysis of the Hip Bones (Ossa coxae) in Turkish Van Cats

This study was carried out to determine the osteometric measurement values of the ossa coxae by using three-dimensional (3D) modeling of the images obtained by computed tomography in Van Cats. In the study, 16 adult Van cats, 8 of which are male ones and 8 female ones, were used. Firstly, cats were anesthetized with the ketamine HCl - xylazine HCl combination. Their images were obtained by scanning through 16 cross-sectional CT devices (Somatom Sensation 16; Siemens Medical Solutions, Erlangen, Germany). Then, The scanned images of the ossa coxae in each cat were transformed into the three-dimensional structure by using MIMICS 20.1 (The Materialise Group, Leuven, Belgium) software program. Later, morphometric (12 linear), volumetric, and surface area measurements were calculated and statistical analyses were performed. In the present study, 12 of 14 measurement parameters of the ossa coxae were higher in males than in females. In the osteometric analysis, it was observed that the greatest length of one half (GL), length between the inner edges of the acetabulum (LA), the greatest breadth across the tuber ischiadicum (GBTI), and the smallest breadth across the bodies of the ischia (SBI) measurement values were significantly greater in male cats than in female cats (P
