Which of the following is the characteristic feature that distinguishes an incised wound from a stab wound?

Explanation

## Distinguishing Incised vs Stab Wounds ### Definition and Key Differences **Key Point:** An incised wound is characterized by a length that exceeds its depth, whereas a stab wound typically has depth greater than or equal to its length. ### Comparative Features | Feature | Incised Wound | Stab Wound | |---------|---------------|------------| | **Length vs Depth** | Length > Depth | Depth ≥ Length | | **Weapon Type** | Sharp-edged (knife, glass, razor) | Pointed, narrow (dagger, stiletto, pointed knife) | | **Wound Edges** | Clean, sharp, minimal tissue bridging | May show tissue bridging, irregular if weapon twisted | | **Tissue Damage** | Minimal surrounding tissue trauma | Deep penetrating injury, may damage vital organs | | **Hemorrhage** | Variable, depends on vessel injury | Often profuse due to deep vessel damage | | **Margins** | Well-defined, no bruising typically | May show bruising at entry point | ### Clinical Significance **High-Yield:** The ratio of length to depth is the PRIMARY distinguishing feature in forensic examination. An incised wound with length 5 cm and depth 1 cm is clearly incised; a wound with length 2 cm and depth 4 cm is clearly a stab wound. **Clinical Pearl:** Stab wounds are medico-legally more significant because they can penetrate body cavities and damage vital organs (heart, lungs, liver, spleen) despite appearing deceptively small on the skin surface. **Warning:** Do not confuse the weapon type with the wound type. A pointed knife can produce either an incised wound (if used with a slashing motion) or a stab wound (if used with a thrusting motion). The wound morphology, not the weapon alone, determines classification. ### Forensic Examination Points - Measure both length and depth carefully during autopsy - Document wound edges under magnification - Note presence of tissue bridging (suggests stab wound) - Assess surrounding bruising and abrasion - Trace the wound tract to identify organs involved
