Study Notes
Types of Wounds
- There are five common types of wounds: abrasion, alteration, incision, laceration, and puncture.
- Abrasion is a wound caused by friction when a body scrapes across a rough surface.
- Avulsion is characterized by a flap.
- Incision is a cut with clean edges.
- Laceration is a cut with jagged edges.
- Puncture is a wound where something passes through or becomes impaled in the skin.
Blunt Force Wounds
- Blunt force wounds can range from mild to severe when a person is struck with a blunt object.
- Examples of blunt objects include pipes, clubs, and fists.
Abrasions
- Abrasions are scratches and scrapes involving outer layers of the skin, including grazes and impact impressions.
- Examination of abrasions can indicate the exact site of where an object struck the skin and the direction the wounding object was traveling.
Contusions (Bruises)
- Contusions are injuries that do not break the skin but result in some discoloration.
- Contusions can be produced post-mortem.
- The force or intensity of a blow cannot be judged by the size or color of the bruise.
- Bruises do not necessarily occur at the site of impact.
Lacerations
- Lacerations are torn, ragged wounds to the skin or internal organs.
- Lacerations can occur as a result of a blow with a blunt instrument or from extreme trauma.
- The edges of a laceration will be abraded (scraped).
- There may be bridging of vessels and nerves within the wound.
- The skin surrounding a laceration may be undercut (separated from the underlying muscle/bone).
Incised Wounds
- Incised wounds are wounds that are usually longer than they are deep.
- They are caused by a sharp item cutting or slashing into the skin, making a long laceration or cut.
Chopping Wounds
- Chopping wounds represent a combination of sharp and blunt force injuries.
- They are typically produced by a heavy or powerful object that has an edge that is somewhat sharp to very sharp.
Defense Wounds
- Defense wounds are any type of injuries that result from an attempt to defend against an assailant using sharp-edged or blunted instruments.
- Such wounds are usually deeply indented stab wounds, but can be either blunt or sharp in nature.
Coup and Contrecoup Injuries
- Coup injuries are located beneath the impact (usually caused by a blow).
- Contrecoup injuries are on the opposite side from where the blow was initiated.
Gunshot and Shrapnel Wounds
- Gunshot and shrapnel wounds are caused by the penetrating power of a projectile propelled by an expansive force of gas or gun powder.
