Sharp Force Injury
Injuries produced with sharp objects capable of cutting or stabbing.
Cutting
An injury created when a sharp-edged object is drawn over the skin, resulting in a wound longer than it is deep.
Stabbing
An injury resulting from a sharp object penetrating the skin.
Incised Wound
Another term for a cut, where the injury is longer than it is deep.
Laceration
A tear produced by blunt force rather than cutting with a sharp object.
Hilt Mark
Injuries that surround a stab wound, indicating maximum insertion depth of the blade.
Defense Wounds
Injuries sustained when a victim attempts to protect themselves from an assailant.
Offensive Cuts
Wounds sustained by the assailant when their hand slips onto the blade during an attack.
Hesitation Cuts
Superficial cuts frequently associated with suicidal stabbings, indicating uncertainty.
Pulsating Hemorrhage
Rapid blood loss resulting from an artery being breached.
Subcutaneous Tissues
Tissues under the skin that can contribute to the depth of a stab wound.
Vasodilation
Widening of blood vessels, which can occur in warm water and prevent clotting.
Self-Inflicted Stab Wounds
Stab wounds inflicted by the victim upon themselves, often superficial and multiple.
Suicidal Stabbings
Stab wounds inflicted with the intent to end one's life, usually involving hesitation cuts.
Arterial Bleeding
Severe bleeding from arteries that tends to be rapid and pulsating.
Venous Bleeding
Slow bleeding from veins that lacks pressure.
Wound Track
The pathway of a wound as it penetrates the skin.
Serrated Blades
Blades that cause indistinguishable wounds unless scraping the skin sideways.
Chopping Instruments
Instruments like meat cleavers and machetes that create gaping wounds with abrasions.
Cleavage Lines of Langer
Lines of tension in skin determined by elastic and collagenous fibers.
Air Embolism
The presence of air in the bloodstream, usually resulting from a neck injury.
Pneumothorax
Air in the chest cavity caused by a penetrating wound.
Disarticulation
Disjointing at the joints typically without fractures.
Dismemberment
Separation of body parts, often with dry edges and lack of bleeding.
Post-Mortem Changes
Changes occurring after death that may alter appearance of injuries.
Depth Measurement
The assessment of how deep a wound penetrates, which can exceed blade length.
Suicide Attempts
Repeated attempts to end one's life, often marked by specific injury patterns.
Aggressive Stabbing
Stabbing that shows movement and struggle between the assailant and the victim.
Autopsy Procedures
Methods employed to examine a body post-mortem, including photography of wounds.
Mechanical Trauma
Injury caused by physical force, often resulting in damage to body tissues.
Abrasion
A wound resulting from scraping or rubbing that may indicate struggle.
Blood Loss Complications
Dangers arising from excessive blood loss due to injuries.
Infection Risk
The potential for infection following a wound, which can complicate healing.
Chemical Comparison
Analysis method to identify broken glass slivers associated with injuries.
Force Required
The amount of pressure needed to inflict a stab wound.
Pain Sensation
Variability of pain perception between the skin surface and internal organs.
Wound Reconstruction
Process of restoring a wound to its original condition post-injury.
Blood Inhalation Effects
Complications resulting from inhaling blood, particularly after neck injuries.
Surgical Emergencies
Critical medical situations that require immediate intervention due to stab wounds.
Victim's Movement
The dynamics of how a victim and assailant interact during a stabbing.
Wound Photographs Protocol
Guidelines followed when photographing injuries during autopsy.
Beverage Container Injuries
Injuries inflicted with broken glass bottles, requiring careful inspection.
Wound Type Identification
Determining the nature of a wound based on its characteristics and patterns.
Distorted Wound Shapes
Atypical appearances of injuries resulting from movement during the stabbing.
Serra-tions Visibility
Appearance of serrations only when engaging the skin surface.
Low Pressure Injury
Types of wounds associated with veins experiencing lower pressure.
Scissors vs. Knife Wounds
Differences in wounds based on the sharpness and tip of instruments.
Blood Volume Loss
The total amount of blood that can be lost from injuries, critical in trauma cases.
Body Surface Dynamics
The effectiveness of body tissues to absorb the thrusts of stabbing.
Historical Stabbing Trends
Patterns observed in previous incidents, informative in forensic studies.
