Abstract
La displasia de cadera es la patología que más frecuentemente imposibilita a un perro entrar a formar parte de las Fuerzas Armadas y Fuerzas y Cuerpos de Seguridad del Estado. Al empezar a criar cánidos en el Ministerio de Defensa, y no siendo posible el diagnóstico de esta alteración antes del año, se propuso en el Servicio Policlínica del Centro Militar de Veterinaria la realización de un programa de screening en el que se medía el índice de distracción mediante una radiografía de distracción y otra de compresión antes de las 20 semanas de edad y realización de la sinfisiodesis juvenil pubiana cuando el índice de distracción superaba el umbral previamente determinado antes de las 24 semanas.El estudio se dividió en dos fases, la primera tenía como objetivo principal determinar si se producía una mejoría significativa realizando este programa de screening y cirugía posterior cuando el índice de distracción era mayor o igual a 0,45 comparando la incidencia en la presentación de displasia de cadera al año de edad en estos perros con una cohorte histórica anterior. Para ello, se realizó un estudio descriptivo ambispectivo en perros Pastor Alemán y Pastor Belga Malinois, en el que la cohorte histórica constaba de 55 animales y la cohorte prospectiva por 91, realizándose 36 cirugías y llegando a fin de estudio 73 perros. Los resultados en la fase I del estudio muestran una mejoría significativa en la ausencia de displasia de cadera al año realizando este programa, obteniéndose el doble de caderas aptas (OR=2,20; IC 95%: 1,03-4,67)...
Canine hip dysplasia is the main pathology that prevents a dog to be admitted as a member of the Armed Forces or the Police Corps. When the Ministry of Defense started breeding dogs in the Military Center of Horse Breeding in Ávila, and not being able to diagnose canine hip dysplasia before the dog has reached one year of age, the Policlinic of the Military Center of Veterinary implemented a screening program to obtain radiographically the distraction index before the puppy was 20 weeks of age and the juvenile pubic symphisiodesis when the distraction index was higher than a previously set threshold and before the puppy was 24 weeks.The study was divided in two phase: the first one with the main objective of testing if the program showed significant differences between a historic cohort and a prospective cohort which was to be operated if the distraction index was equal o higher than 0,45. An ambispective descriptive essay was made in which the historic cohort consisted of 55 animals and the prospective cohort of 91, 36 surgeries were made and 73 dogs reached the end of the study. The results of this phase showed a significant improvement in hips conformation, doubling the production of dogs with suitable hips (OR=2,20; IC 95%: 1,03-4,67)...
