The analysis of elbow radiographs of 21 272 dogs, examined during 1988-2005, enabled us to estimate the frequency of canine elbow dysplasia in 90 breeds of dogs. Relation between breeds and incidence of elbow dysplasia was established statistically. The percentage of affected specimens was surprisingly low at 0.7% (150 dogs), and distinctly lower than the percentages reported by several authors in Germany, the USA, and other countries. The highest number of dogs affected was found in 47 (1.7% of total number studied) German Shepherds, in 25 Rottweilers (2%), and in 17 Dachshunds (0.5%). Breeds most often affected were of FCI group II, namely English Mastiffs (9%), Dogue de Bordeaux (8.5%), Neapolitan Mastiffs (8.3%), and Newfoundlands (4.6%). Elbow dysplasia was also found with significant frequency in breeds of the FCI group VIII - Labrador Retrievers (4.3%) and Golden Retrievers (4.4%). Fragmented coronoid process (FCP) was most frequently diagnosed (58.0% out of 150 affected specimens). Ununited anconeal process (UAP), was diagnosed in 32.0%. FCP and UAP together were present in 6.7% of the dysplastic specimens. No cases of osteochondritis dessecans and joint incongruity were found. UAP cases were most common in German Shepherds, while FCP occurred most frequently in Dogues de Bordeaux and Rottweilers.
This article aims to compare the treatment of fragmented coronary process in the context of clinical results. Forty-two dogs of both sexes, aged from 5 months to 2 years, all belonging to the predisposed breeds, were tested. Each patient was subjected to radiological and clinical examination on the basis of which was classified into one of four degrees of dysplasia according to criteria of the International Elbow Working Group. Then the decision towards specific therapeutic procedures, operational or pharmacological, was taken. About 4-12 weeks after the surgery, the control examination was performed. It allowed to assess the post-surgery mobility. The results depended on the age of animal at which treatment was carried out, and the degree of degenerative changes in the joint. The studies have shown that the best results were obtained in a group of dogs aged 5-9 months, in whom a dynamic ulna osteotomy was performed. This indicates the need for early diagnosis of disease and rapid implementation of the treatment, to eradicate the problem of radial- ulnar incongruity, thereby preventing the development of further changes within the joint.
The objective of the study was to present the results of radiographic evaluations of elbow joints in dogs with recognised elbow dysplasia. The research covered 40 dogs, and both elbow joints of each animal were examined and graded. In a dysplastic joint, one or a few conditions resulting in the displasia were assessed as well as a degree of degenerative joint disease. In addition, the incidence of other disorders of the skeletal system was considered. In the dysplastic joints, fragmentation of the medial coronoid process (in 88.7%), along with joint incongruity (in 71.8%) were most frequently observed. The lesions were manifested with relatively slight clinical signs. The dogs were usually brought for the clinical and radiographic examinations when the progression of arthritic changes reached the 2nd grade in at least one joint (50% of the animals examined). A possibility for early detection of elbow dysplasia, if some other diseases of the skeletal system did not occur, was 20% in the examined group of dogs.
