Comparison between new design interlocking nail with plate fixation and intramedullary pin with external skeletal fixation in long bone fracture in the dogs

Abstract

New design interlocking nail and plate fixation was used in comminuted femur fracture in an old dog that the results showed primary bone healing and she had been quickly weight baring in fifteenth day after surgery, and could be walk in twenty day after operation. Another case was a young dog that showed transverse fracture of both humerus and one transverse fracture of femur that were repaired by intramedullary pin and external skeletal fixation. The results showed secondary bone healing of these three bone fractures and she could be walk after 2 months of operation. An old dog did not show any complication but a young dog showed pin migration in femur healing. This study revealed that the superior result in bone healing was found in rigid fixation by new design interlocking nail and plate fixation greater than intramedullary pin with external skeletal fixation.
