This document discusses different ways to classify wounds. There are several classification systems including by etiology, duration of healing, degree of contamination, and morphological characteristics. Classifying wounds is important to plan proper treatment, ensure standardized documentation, and provide prognostic information. The main types of wounds discussed are blunt trauma wounds, burn injuries, penetrating wounds, and incisional wounds. Classification helps determine whether a wound can be sutured or needs to heal by secondary intention.
