Abstract: This study was carried out on 4 dogs with bilateral carpal hyperextension that treated in Ankara University, Faculty of Veterinary Medicine Orthopaedics and Traumatology Clinic. In clinical examination, it was found that the angle of the stepped carpal joints were between 250° and 270°. Furthermore, there were wounds at volar sites of carpal joints. There were no lesions seen radiographically. In 3 cases, total arthrodesis was made by applying a single Steinmann pine, passing intramedullary through metacarpus III, to os carpi centrale and radius, in one case total arthrodesis was made by applying three Steinmann pines passing through metacarpus 2, 3, 4 intramedullarly with the same technique. As the dogs grew up and get heawier, the pines were broken in cases with single pine. This situation didn't effect carpal fusion. In the case with 3 pine, there was not any similar condition. Operative procedures were carried out for the opposite carpal joints, after it was detected that carpal fusion was complete after a 7 weeks postoperative observation. In treatment of bilateral carpal hyperextension in dogs, we decided that arthrodesis of radio-carpal, mid-carpal and carpo-metacarpal joints by applying multipl pines is more reasonable than applying a single intramedullar pine.
