Standard Hip Ventrodorsal Leg Extended View In The Diagnosis Of Canine Hip Dysplasia: A Review

Abstract

Canine hip dysplasia (CHD) is hereditary developmental condition that involves a lack of conformity between the femoral head and acetabulum. It invariably leads to osteoarthritis. We hereby review the standard hip ventrodorsal leg extended view to be adopted by our Tanzanian veterinarians. Diagnostic radiography is the only definitive method used to detect CHD. In 1961, a report from a panel of the American Veterinary Medical Association on CHD indicated that, the standard hip ventrodorsal leg extended view is the most preferred. This standard view has become the most common radiographic view for the evaluation of CHD. The standard hip ventrodorsal led extended view is more practical and is technically less demanding. It can be easily reproduced in a practice situation. The use of this view by the Orthopaedic Foundation for Animals (OFA) established in 1966 has contributed significantly to the radiographic evaluation of canine hip joint and
control of CHD. Adoption of this technique by our veterinarians is important in the diagnosis and control of CHD in Tanzania. This will serve to prevent losses to pet owners, dog breeders and dog buyers. Radiological screening and selective breeding programmes have been successfully used to control CHD in several countries. We recommend this view to be used in Tanzania for CHD diagnosis in animals suspected to show hind limb lameness and as routine for breeding dogs.
