Abstract:
Fractures are routinely observed in the surgical practice of small animals, caused mainly by automobile accidents, firearms, and falls. Biological osteosynthesis is commonly used in irreducible comminuted fractures located in diaphysis of long bones. The objective of this study was to report the success of a closed biological osteosynthesis by means of an external fixator type I, performed in an irreducible comminuted fracture in the middle third of a humerus in a large breed dog, caused by an automobile accident. The patient was submitted to biological osteosynthesis with the use of external skeletal fixator applied in a closed manner, without any manipulation of the fracture focus. With the total restoration of the bone, visualized by the imaging examinations and the clinically observed function of the limb, it was possible to conclude that the application of Type 1 external fixator in a closed manner allowed the fracture alignment without manipulation of the fragments even though an old fracture.
