Abnormal development of the components of the elbow joint. The humerus radius and ulna all meet at the elbow, and if these bones do not fit together correctly, it can cause problems during articulation.
Primarily a genetic condition, elbow dysplasia can also develop if the dog was an obese puppy, or if too much exercise was allowed, including frequent and repetitive use of the stairs, and encouraged jumping, such as agility at an early age. An injury or trauma can also develop into elbow dysplasia.
The dog may present with lameness to the foreleg, a reduced range of motion, abduction of the elbow, or a bowed leg stance. Other symptoms may include a reluctance to exercise and the inability to lie down in a controlled manner. They may have difficulty walking the stairs, and show reluctance to jump in or out of the car. The dog may limp in one or both legs, which is often accompanied by a head bob. The head will nod down when the bad leg meets the ground and is lifted when the good leg meets the ground. There may be thickening or swelling around the joint, and in some cases, there may be no symptoms.
Elbow dysplasia will often lead to arthritis
