With Hips Across the board the databases evaluate radiographs of the hip joint looking at the bones of the pelvis and femur and their relationship to each other, the hip joint. The radiographs are checked for appropriate size and shape of the bones, any signs of obvious pathology such as degenerative joint disease, DJD, and they are used to asses the degree of laxity e.g. how tightly the head of the femur fits into the acetabulum. Variations in any of these areas can lead to a diagnosis of hip dysplasia.
OFA testing is decided by a consensus of the 3 independent outside evaluations and the end result is the average of all three opinions. Opinions, even expert opinions, are always subject to confounding variables, but that does not mean the tests do not provide value. By using the expert opinion and matching it with the current health of the dog, i.e. with a HD diagnosis is there any lameness, we can best evaluate the orthopedic health of each dog. In addition to the radiographs, it is important to look at the big picture when deciding on the breeding value of an individual.
- What are the hip scores in the litter mates or other first generation relatives?
- Do any of the other dogs in the close pedigree have hip or other orthopedic issues?
- Does the dog in question have any other significant health, temperament or conformation issues?
