ABSTRACT A retrospective study was made of 335 dogs with elbow osteochondrosis that had been seen at the Royal Veterinary College in 1977 to 1987. The most commonly affected breeds were the labrador, retriever and rottweiler. Males were affected more often than females. The condition was bilateral in 50 per cent of cases and the peak age for the onset of lameness was four to six months. In rottweilers, the lesions found at exploratory arthrotomy were predominantly abnormalities of the coronoid process, while in retrievers and labradors lesions most commonly affected the medial humeral condyle or the coronoid process. A scoring system for grading the standard projection (lateral and postero‐anterior) radiographs was devised and the score was correlated with the lesion found at surgery. Some cases were reviewed radiographically and any alteration in the degree of periarticular arthrosis, seen as an increase in radiographic score, was noted. The exact extent of the lesion found at surgery was recorded diagrammatically in 65 cases. It did not prove possible to predict from the radiographic score the nature and extent of the lesion and no correlation could be found between the radiographic score [and clinical degree of lameness. The scoring system did have some merit for reviewing cases because an increase in score indicated the extent to which joint changes had advanced.
