[Clinical and radiologic evaluation of the integrity of medial and lateral collateral ligaments of the elbow in dogs].
Closed reduction is the best therapy in most cases of luxation of the elbow. Clinical retrospective studies showed the presence of arthrosis in 50% of the cases treated with closed reduction (Meyer-Lindenberg et al., 1991) and persisting medial instability after the reduction in more than 50% of the cases. In the present study, the biomechanic of both medial and lateral collateral ligaments was analyzed after selective severing of those ligaments. Severing of the medial collateral ligament led to an average increase of the pronation of 30 degrees with the presence of crepitus on the lateral aspect of the elbow during passive motion. The medial instability of the elbow could be evidenced clinically as well as radiographically. Severing of the lateral collateral ligament resulted in an average increase of the supination of 15 degrees. No evidence of subluxation could be diagnosed using palpation or radiology. Craniocaudal stressed radiographic views of the elbow in pronation are the most helpful to document damages of the collateral ligaments of the elbow.
