Abstract

Amaç: Bu çalışma, sağlıklı Alman Çoban köpeklerinde pelvis geometrisinin ventro-dorsal pozisyonda röntgen çekimleriyle incelenmesini amaçlamaktadır. Gereç ve Yöntem: Çalışmada, 12 dişi ve 12 erkek olmak üzere toplam 24 adet sağlıklı Alman Çoban Köpeğinin pelvik ve femoral morfometrik ölçümleri değerlendirilmiştir. Bunun için köpeklerin önce klinik muayene testleri yapıldı, sağlıklı olarak geçemeyen köpekler çalışma bünyesinden çıkartıldı. Sağlıklı kabul edilen vakalar Fédération Cynologique Internationale (FCI) standartlarında kalça skorlaması yapmak üzere simetrik ventro-dorsal pelvis röntgeni çekildi. Bulgular: Elde edilen bulgular, cinsiyetler arasında özellikle sol iliak uzunluk (dişilerde 100,35+2,25, erkelerde 105,68+6,65), sağ iliak uzunluk (dişilerde 101,28+2,38, erkelerde 106,41+7,78), sol femur eğim açısı (dişilerde 121,83+2,69, 124,66+2,90) gibi parametrelerde anlamlı farklılıklar olduğunu göstermiştir. Erkek köpeklerde bu ölçümlerin dişilere göre daha yüksek olduğu belirlenmiştir. Buna karşın, sağ ve sol Norberg açıları sırasıyla (dişilerde 103,83+2,91, erkeklerde 103,16+2,36) ve (dişilerde 104,91+2,67, erkeklerde 104,58+3,08), gibi kalça displazisi ile ilişkili parametrelerde cinsiyetler arasında anlamlı bir fark gözlenmemiştir. Sonuç: Çalışma, pelvik morfometrik ölçümlerin cinsiyete bağlı farklılıklarını ortaya koyarken, bu verilerin kalça displazisinin değerlendirilmesinde tamamlayıcı bir yöntem olarak kullanılabileceğini öne sürmektedir. Radyografik görüntüleme ve dijital ölçüm teknikleri, pelvik yapıların değerlendirilmesinde güvenilir ve tekrarlanabilir sonuçlar sunmuştur. Ancak, çalışmanın sınırlı örneklem büyüklüğü ve tek bir ırka odaklanması, bulguların genellenebilirliğini kısıtlayabilir.

Examination of Pelvic Geometry in Healthy German Shepherd Dogs in Ventro-Dorsal Position X-Rays

Abstract

Objective: This study aims to examine the pelvic geometry of healthy German Shepherd dogs through ventro-dorsal radiographs.
Materials and Methods: In the study, pelvic and femoral morphometric measurements of a total of 24 healthy German Shepherd Dogs, 12 females and 12 males, were evaluated. For this purpose, the dogs were first subjected to clinical examination tests, and the dogs that did not pass healthily were removed from the study. In cases considered healthy, a symmetrical ventro-dorsal pelvis x-ray was taken to perform hip scoring according to Fédération Cynologique Internationale (FCI) standards.
Results: The findings indicate that there were significant differences between sexes in certain parameters, particularly left ilial length (100.35 ± 2.25 in females, 105.68 ± 6.65 in males), right ilial length (101.28 ± 2.38 in females, 106.41 ± 7.78 in males), and left femoral inclination angle (121.83 ± 2.69 in females, 124.66 ± 2.90 in males). These measurements were found to be higher in males compared to females. In contrast, no significant differences were observed between sexes in parameters related to hip dysplasia, such as the right and left Norberg angles (103.83 ± 2.91 in females, 103.16 ± 2.36 in males) and (104.91 ± 2.67 in females, 104.58 ± 3.08 in males), respectively.
Conclusion: The study highlights the role of pelvic morphometric measurements in identifying gender-related structural differences and suggests their potential as complementary tools in assessing hip dysplasia. Radiographic imaging and digital measurement techniques provided reliable and reproducible results for evaluating pelvic structures. However, the study's limited sample size and focus on a single breed may restrict the generalizability of the findings.
