Hip dysplasia is a developmental, multifactorial, genetically influenced condition that is characterized by ill-fitting or loosely-fitting hip joints and the development of secondary degenerative joint disease (arthrosis).

As hip dysplasia is a developmental disease, it only manifests itself radiological after the age of  about 6 months. There is no doubt about the fact that the tendency to develop hip dysplasia is inherited but environmental factors like excessive protein intake and excessive strenuous exercise at a very young age play a role in the degree of dysplasia that is eventually manifested.

Genetically susceptible dogs become dysplastic when the primary muscle mass that supports the joint fails to mature at the same rate as the skeletal structures. The resultant disparity between soft tissue strength and biomechanical forces during skeletal growth is manifested as a loss of congruency between the articular surfaces of the acetabulum and the femur head.
This results in joint laxity and eventual hip arthrosis.

The SAVA together with KUSA runs a national hip/elbow dysplasia certifying scheme according to guidelines set up by the FCI and International Elbow Working Group.  The grading of a dogs (and cat’s)  hips and elbows according international standards gives breeders an idea of the hip and elbow status of their dogs or cats which has to be considered when breeding these animals. Several dog breeds have specific minimum grading requirements before the dog or bitch may be bred. The radiographs taken by your veterinarian are sent s to a veterinary radiologist, one of a group, appointed by the SAVA. These are veterinarians who are recognised as specialist radiologists by the SA Veterinary Council and some of them are also recognised as specialists by the European Association of Veterinary Diagnostic Imaging.  These radiologists give an opinion as individuals but an appeal process is in place for those owners who wish to do so.  KUSA and other breed societies will only accept certificates from the members of the panel.

The panel of radiologists has a chief scrutineer who acts as liaison person between the radiologists and the SAVA as well as KUSA.

The criteria for making and submitting radiographs are very strict and are in accordance with the guidelines laid down by the international bodies. Details of the procedures can be obtained from the KUSA website, SAVA website under members section and from the radiologist that the veterinary practice uses.
