Module 11: Sharp Force & Blunt Force Flashcards
A scratch caused by friction, gasgas
abrasion
clean cut, longer than deep
incision
True or False
You can tell the direction of force based on the tail of incision.
True
Cut but deeper than wide
Stab
True or False
Stab wound can tell the direction of force but not the type of knife.
False. It can tell the type of knife.
True or False
Puncture is parallel to the skin or bone surface.
False. Perpendicular
Messy-looking wound caused by a tearing or crushing force. Putok ng laman.
Laceration
Like abrasion but the tissue is torn away. Caused by tearing force.
Avulsion
Putol
Amputation
Pasa
Contusion
Injuries caused by focused points or sharp objects which results to punctures and incisions.
Sharp force injuries
What objects can cause SFI?
knives, broken glass, needles, serrated blades too.
Characteristics of SFI
- sharp and clean wound edges
- stab, slash, and puncture wounds
- (2 remaining sa true or false)
True or False
- depth and direcion of the wound depend oon the sharpness, force, focus, and angle of the object.
- SFI does not leave distinct patterns
- True
- False
SFI Mechanisms
- Intentional: stabbings, assaults, homicides
- Accidental: mishandling
- Self- inflicted
Forensic considerations of SFI
- analysis of SFI used in f. investigations
What can be infer from SFI?
- weapon type and size
- direction of force
- depth and angle of penetration
- number and location of wounds
True or False
SFI can tell specific weapon size
False. Not specific.
True or Flase
It is easy to tell if blade is serrated or not , or of single- or double-edged blade
False. Hard.
True or False
Penetrating wound: w/ exit wound
Perforating wound: w/o
False. Baliktad
- Result form impact without sharp edges, such as fists, bats, or falls.
Blunt force injuries
Injuries from BFI
- tissue damage
- fractures
- contusions
True or False
It is BFI even if the objects penetrates the skin.
False
Characteristics of BFI
- lack of sharp edges
- injury varies depending on the force, surface area, and velocity of impact
- causes bruises, abrasions, fractures, and internal organ damage
Examples of BFI
- contusions
- hematomas
- lacerations
BFI: Mechanisms
- assault and physical altercations
- fall
- sport-related activities
- motor vehicle accidents
Forensic Considerations in BFI
- analysis of BFI
What can be infer from shape, size, and distribution of injuries?
- force, direction, and nature of impact
-object identification
Complications from injuries
- excessive bleeding
- organ damage
- risk of bacterial infection due to exposure to external envi.
List down
- internal organ damage due to BFI
- longer-term consequences
- injuries to brain, spleen, liver
- chronic pain, disability, psychological trauma
