Laceration in Small Mammals

A laceration is a wound produced by the tearing of body tissue. The skin is often involved. Unlike an incision with smooth edges, a laceration is often jagged and irregular.

There can be variable degrees of damage to the underlying body tissue and structures, depending on the depth and force of the trauma that caused the laceration. Minor trauma may damage the skin only. Major trauma may damage deeper muscles and tendons or extend into the abdominal or chest cavities.
