Abstract
The present work was conducted on 6 clinical cases of dogs with fractures of femur (5) or humerus (1). In all the animals, the fracture was immobilized by an internal fixation technique using an appropriate size titanium elastic pin. The fracture gap was filled with hydroxyapatite-collagen granules. Postoperative radiographic evaluation on days 15 and 30 revealed mild to moderate periosteal reaction in four animals. Fracture union was seen in three animals by 60th day and in other three animals by 90th day. Post-surgery clinical examination revealed a continuous reduction in lameness and increase in weight-bearing. Based on the results, it was concluded that hydroxyapatite-collagen composite could be used as an alternative to bone graft to fill the fracture defect.
