[Elbow dysplasia in the dog].

Elbow dysplasia (ED) is a common developmental malformation in many breeds over 20 kg bodyweight. It may affect as many as 50% of all dogs within a breed. Arthrosis and poor performance may result. The most common forms of ED are fragmented medial coronoid process, osteochondrosis of the medial humeral condyle and loose anconeal process. There is evidence for the existence of a hereditary disposition for osteochondrosis in Labrador retrievers. In Sweden selection of ED-free dogs for breeding resulted in reduction of frequency and degree of severity of ED in the offspring. Adoption of a similar breeding program for Switzerland is suggested.
