A Clinical and Radiographical Study on Augmentation of Fracture Healing in Long Bones of Dogs Using Synthetic Nanohydroxyapatite

Long bone fractures in six dogs were stabilized with intramedullary pinning and synthetic nanohydroxyapatite (Nha) graft material was deposited at the fracture site intra-operatively. The fractures were classified according to AO ASIF method of classification and the outcome of open reduction and internal fixation was evaluated based on clinical and radiological studies, on 7th, 15th, 30th and 45th post- operative days. Post-operative weight bearing and angulation and lameness grading, radiographic evaluation for alignment and implant stability were also evaluated. The stabilization technique proved to be satisfactory in all the cases. The radiographic score indicated better long bone fracture healing with Nha alone as a graft.
