Displasia de codo en caninos de Medellín, Colombia: estudio retrospectivo

The study aimed to determine the frequency of elbow dysplasia (ED) in canines by evaluating radiographs taken in veterinary clinics in the city of Medellín and its Metropolitan area between 2018 and 2020. Frequency tables and simple logistic regression were used with association between variables with the calculation of ED proportions according to sex, age and breed. A total of 292 radiographic studies were analysed. A greater proportion of cases was found in males (59%) than in females (41%), with 58.6% being older than 5 years. The Golden Retriever, Labrador Retriever, English Bulldog, Pug, Pitbull, Rottweiler and Mountain Bernese breeds had the highest presentation of ED in the studied population and showed a significant association between these breeds and the development of ED. A greater proportion of affected males was found compared to females. The present study shows a high frequency of ED in some breeds, with articular incongruity (AI) being the predominant primary lesion and osteoarthrosis (OA) being the most frequently associated secondary lesion.
