Elbow dysplasia is a general term used to identify an inherited polygenic disease in the elbow of dogs. Three specific etiologies make up this disease and they can occur independently or in conjunction with one another. These etiologies include:
Studies have shown the inherited polygenic traits causing these etiologies are independent of one another. Clinical signs involve lameness which may remain subtle for long periods of time. No one can predict at what age lameness will occur in a dog due to a large number of genetic and environmental factors such as degree of severity of changes, rate of weight gain, amount of exercise, etc. Subtle changes in gait may be characterized by excessive inward deviation of the paw which raises the outside of the paw so that it receives less weight and distributes more mechanical weight on the outside (lateral) aspect of the elbow joint away from the lesions located on the inside of the joint. Range of motion in the elbow is also decreased.
Elbow dysplasia has multiple inherited etiologies which may occur singularly or in combination. These etiologies include fragmented medial coronoid (FCP) of the ulna, osteochondritis of the medial humeral condyle and ununited anconeal process (UAP). The most sensitive view used to diagnose secondary degenerative changes in the elbow joint is an extreme flexed medio-lateral view of the elbow which is required by the OFA and recommended by the International Elbow Working Group. The veterinary radiologists are most interested in the appearance of the anconeal process of the ulna.
When there is instability of the elbow joint due to elbow dysplasia, one of the most sensitive radiographic findings is new bone proliferation (osteophytes) on the anconeal process of the ulna associated with secondary developmental degenerative joint disease.
Bone proliferation can be very subtle to visualize in some dogs and may require the use of a special light source (hot light) rather than a traditional view box to diagnose it. Other arthritic findings such as sclerosis in the area of the trochlear notch of the ulna and bone spurs at joint edges are also reported. If fragmentation of the medial coronoid only involves the cartilage, it may not be seen radiographically but occasionally if the bone is also fragmented, it can be visualized as a separate calcific opacity superimposed over the radius.

They are great! They fit me in for an emergency appointment same day and are very professional in manner. Dr Rutledge was so gentle with our furbaby pitbull Kilo and the service was phenomenal. Within 20 minutes of blood being drawn we found out he had Lyme. The pricing was very reasonable. I highly recommend taking your pets to this vet. I'm beyond pleased and relieved. Thank you Cherry Ridge Vet.
