Arthrosis with special reference to the elbow joint of young rapidly growing dogs. II. Occurrence, clinical and radiographical findings.
Occurrence, clinical and radiographical findings in ununited medial coronoid process in the ulna and osteochondritis dissecans in the humeral condyle in dogs are presented. One hundred and twelve dogs were examined because of forelimb lameness. Lesions were mostly seen in young dogs of heavy breeds especially the Rottweiler. The ratio male: female was about 2:1. Most of the dogs had bilateral lesions. The lameness varied between grade 1 and 3, judged according to a scale ranging from 1 to 5. The affected limbs were somewhat rotated outwards from the elbow and down. Since the ununited coronoid process is almost impossible to detect on a plain radiograph, it is necessary to look for the presence of secondary developed osteophytes, indicative of an arthrosis. Diagnosis is based upon clinical and radiographical findings, the age and the breed of the dog taken into consideration. Osteochondritis dissecans in the humeral condyle is usually easily seen on the dorsopalmar radiograph.
