The healing of femoral neck fractures in dogs. The use of intraosseous venography and India ink staining.

This study evaluates healing fractures of the femoral neck in dogs by using standard radiography, intraosseous venography, India ink staining and histology. The 45 animals were divided into three groups, one of which was not treated, but in the other two the fracture was fixed with a screw or two Kirschner wires. Our results suggest that, when intraosseous venography was positive India ink injection was also positive, and the late phase of fracture healing was reached.
