Elbows 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:
a) Osteochondritis of the medial humeral condyle in the elbow joint (OCD)
b) Pathology involving the medial coronoid of th ulna (FCP)
c) Ununited anconeal process (UAP)
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 weitht 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 elbows is also decreased.
