HD - HIP DYSPLASIA

 

The term Hip Dysplasia can be used to describe a number of developmental problems and other abnormalities involving the hip joint in dogs. Thankfully it is quite rare in our breeds.

Hip dysplasia (HD) is a common inherited orthopaedic problem of dogs and a wide number of other mammals. Abnormal development of the structures that make up the hip joint leads to subsequent joint deformity. ‘Dysplasia’ means abnormal growth. The developmental changes appear first and because they are related to growth, they are termed primary changes. Subsequently these changes may lead to excessive wear and tear. The secondary changes may be referred to as (osteo)arthritis (OA), (osteo)arthrosis or degenerative joint disease (DJD). Later one or both hip joints may become mechanically defective. At this stage the joint(s) may be painful and cause lameness. In extreme cases the dog may find movement very difficult and may suffer from pain. It was in the light of this knowledge that the British Veterinary Association (BVA) and the Kennel Club (KC) developed a scheme some 40 years ago to assess the degree of hip deformity of dogs using radiography.

 

To date radiographs (X-rays) from more than 250,000 dogs have been assessed providing a standardised reflection of the HD status of those dogs that have been examined. This information is primarily of use for breeders. Currently 126 breeds are surveyed by the scheme in the UK.
