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.
