Bites Pastuerella multicoda is a common organism found in animal bites. Human bites are another issue all together. Small dogs which grip and shake their prey generate extensive, crushing injuries. Those which rip and tear create a mixture of crushing, penetrating and laceration. Others such as cats pounce and hold which creates deep penetrating wounds.
Humans create a mixture of crushing, tearing and incising injuries worsened by a mixed mouth flora.
An injury that results from shearing forces literally ripping the skin from the underlying tissues. Blood vessels connecting the dermis to underlying muscle or periosteum are ruptured and the skin dies. Sometimes the skin appears to be still attached but moves around the limb like a glove, hence the name of the injury. Extensive skin grafting is required and the end results are generally of poor cosmetic appearance.
