                                       Hip and elbow dysplasia

The programme
Dysplasia is a condition caused by osteochondrosis, a genetic, progressive disease of cartilage and bone and is often a cause of lameness in young large-breed dogs. It develops primarily in the first twelve months of age and, particularly in young dogs, can be difficult to diagnose. The NZVA Hip and Elbow Dysplasia scheme provides veterinarians with a scheme for accurate evaluation of hip and elbow dysplasia in affected breeds of dogs.

What's involved
Veterinarians are required to submit radiographic plates and supporting documentation to our panel of veterinarians trained in the precise reading of canine joint radiographs. The plates are evaluated, graded and certified by at least two of our panellists according to the degree of osteoarthritic changes. Results are recorded on our register which provides information by breed. An independent veterinary radiologist will act as a referee if necessary.

Digital submissions
DICOM format only; clearly name the individual files e.g. Left Elbow, Right Elbow, Hips, microchip number and registered name of the dog (if applicable). Please provide two CDs.


Selective breeding only from dogs with known good hip and elbow joints can reduce the incidence of dysplasia in future generations. This quality assurance programme helps veterinarians score dysplasia and identify and categorise dogs with 'excellent', 'good', 'suspect' or 'bad' joints.HD and ED...
