Deformidade angular em rádio canino decorrente de má união de fratura: relato de caso

Abstract

In dogs, angular deformities of the thoracic limb are commonly found, and generally affect the radius and ulna. The causes are varied and may be related to disorders in bone growth resulting from trauma to the radial or ulnar physis, chondodystrophy or chondrodysplasia, genetic inheritance, metabolic disorders, nutritional deficiency, premature closure of the distal physis of the radius and ulna or poor union of fractures. The present work aims to report a case of angular valgus deformity of the distal radius in a canine patient, caused by fracture malunion, treated by corrective osteotomy using the CORA method. After locating the center of angular rotation of the deformity, the limb underwent the CWO (Closing Wedge osteotomy) technique. After 60 days, the patient was already walking normally and was discharged. With this report, we can conclude that the CWO technique for this case was demonstrated to be effective and that the CORA method is essential for locating and planning corrective osteotomies.
