In medico-legal examination of wounds, which of the following characteristics is most useful in distinguishing an incised wound from a lacerated wound?

Explanation

## Distinguishing Incised from Lacerated Wounds **Key Point:** The hallmark of an incised wound is clean, sharp margins with minimal surrounding tissue damage, whereas a lacerated wound shows irregular, jagged margins with tissue crushing and bruising. ### Incised Wound Characteristics - Clean, sharp margins - Minimal tissue loss - No bruising or crushing of wound edges - Caused by a sharp instrument (knife, blade, glass) - Bleeding is profuse due to clean vessel division - Healing is better with minimal scarring ### Lacerated Wound Characteristics - Irregular, jagged, torn margins - Tissue crushing and bruising at edges - Significant tissue loss - Caused by blunt force or blunt object - Tissue bridging may be present across the wound - More prone to infection and poor healing ### Medico-legal Significance | Feature | Incised Wound | Lacerated Wound | |---------|---------------|------------------| | Margins | Clean, sharp | Irregular, jagged | | Tissue damage | Minimal | Extensive crushing | | Bleeding | Profuse | Moderate | | Cause | Sharp instrument | Blunt force | | Tissue bridging | Absent | May be present | | Forensic implication | Suggests weapon | Suggests blunt trauma | **High-Yield:** In medico-legal cases, the presence of clean margins strongly suggests a sharp instrument injury, which has important implications for reconstructing the mechanism of injury and identifying the weapon. **Clinical Pearl:** Tissue bridging (strands of tissue crossing the wound) is characteristic of lacerated wounds and occurs because blunt trauma tears tissue irregularly, leaving some tissue intact across the wound depth.
