Here you will find links to information on elbow dysplasia and testing schemes, including from the International Elbow Working Group, The Orthopedic Foundation for Animals (OFA), the British Veterinary Association (BVA) and the Fédération Cynologique Internationale (FCI).
The elbow dysplasia (ED) grading scheme is based on that of the International Elbow Working Group, IEWG, as follows:
• Grade 0 = a radiographically normal elbow.
• Grade 1 = there is no visible primary lesion but secondary new bone (osteoarthritis) up to 2mm in depth is present at any site around the elbow joint.
• Grade 2 = (a) a primary lesion is visible (eg. medial coronoid disease or ununited anconeal process) without visible osteoarthritis OR b. no primary lesion is visible but osteoarthritis of more than 2mm and up to 5mm in depth is present at any site around the elbow joint.
• Grade 3 = (a) both a primary lesion and any amount of osteoarthritis are visible OR b. no primary lesion is visible but osteoarthritis over 5mm in depth is present at any site around the elbow joint.
The overall grade is that of the worse of the two elbows.
It is strongly recommended that breeders wishing to reduce the risk of elbow dysplasia should select their breeding stock (both dogs and bitches) only from animals with an overall grade of 0.
Dogs with elbow grades of 2 or 3 have marked osteoarthritis likely to be due to ED, with or without a visible primary lesion. There is a significant chance of ED being passed on to the offspring.
Dogs with elbow grades of 1 show mild or early osteoarthritis which is also likely to be due to ED. They should only be used for breeding with caution, taking into consideration the ED grades of as many relatives as possible, as well as the results of other health tests and characteristics.
