Atlarda kemik lezyonlarının belirlenmesinde radyografi sık kullanılan görüntüleme yöntemlerinden birisidir. Çalışmada,

halk elinde bulunan ve çeşitli nitelikteki yük taşıma ve ulaşım işlerinde kullanılan atlardaki alt ekstremite ve ayak

bölgesi kemik lezyonlarının taranarak elde edilen sonuçların literatür veriler ışığında tartışılması amaçlandı. Çalışma

toplam 30 adet araba atında yapıldı. Anamnez sorgulaması ve klinik muayenesi tamamlanan atların; ön ve arka, sağ

ve sol alt ekstremite ve ayaklarının çeşitli pozisyonlarda radyografik çekimleri yapıldı. Her bir at için elde edilen radyografik

görüntüler ayrı ayrı incelendi. Belirlenen lezyonlar yerine ve niteliğine göre tasnif edilip, tanımlayıcı istatistik yapılarak

değerlendirildi. Radyolojik olarak incelenen atların %80’inde değişik nitelikte lezyonlar saptanırken, %20’sinde herhangi

bir lezyon ile karşılaşılmadı. Atların %66.7’sinde osteoarthritis, %70.8’inde süro, %50’inde sesamoiditis, %

54.1’inde periosteal kemik formasyonu tespit edildi. Lezyonların ön ve arka bacaklardaki dağılımı sırası ile %12.5 ile %

8.3 iken, atların %79.2’ünde hem ön hem de arka bacaklarda lezyon tespit edildi. Belirlenen lezyonların hemen hepsinin

kronik nitelikli olduğu söylenebilir. Sonuç olarak, bu tip ağır işlerde kullanılan atların refah problemlerinin ortadan

kaldırılması gerektiği anlaşılmıştır.

Clinical and Radiological Evaluation of the Bone Lesions in Lower Extremity and Foot Region in Draft Horses

Öz

In this study; it is aimed to discuss the results, which are obtained from the evaluation of the lower extremity

and foot region bone lesions in the horses, which are used in various qualities like cargo transportation and transportation,

in the light of the literature. Radiography is one of the commonly used imaging techniques for diagnosis of bone

lesions in horses. The radiography is one of the most commonly used imaging methods to determin bone lesions in

horses. In this study, we used 30 horses that work as an draft horses. After clinical examination and anamnesis of horses,

radiographic exposures were made. All horses were taken x-ray for distal exstremities. Radiographic images were

analyzed separately for each horses and all lesions were classified for localization and propert. All data were evaluated

by descriptive statistics. After radiological examination, we observed that 80% percent of horses had different lesions

however, we did not observe any lesion for 20% percent of horses. 66.7% percent of horses had osteoarthritis,

70.8% percent of horses had splint 50% percent of horse had sesamoiditis, 54.1% percent of horses had periosteal

bone formation. The distribution of the lesions in the front and hind extremity respectively, 12.5% and 8.3%. 79.2%

percent of lesion were determined both front and hind extremity in our horses. Almost all lesions that were determined

was chronic lesions. Challenges of working and living conditions was found to be effective for lesion procedure. As a

result, it has been understood all those welfare problems of heavy-duty horses need to be dealt.
