ESTABLISHMENT ON ANIMAL MODEL OF SKIN AVULSION INJURY

Objective:To study the mechanism of avulsed tissue necrosis and the way of treatment through estabilshing animal model of skin avulsion injury in pigs. Methods:A 12cm×14cm random avulsed flap was created in hind leg of pig by mimicking the mechanism of causing avalsion injury and by applying the avulsion injury created machine and made post injury tissue pathology. Results:There were injuries at different levels in skin,dermis tissue and vessels. Subcutaneous separated from muscle.Thrombosis and hemorrhage could be found in some vessels. Conclusion:Skin avulsion injury created in hind leg of pigs is similar with one caused by traffic accident. [
