What are the four major types of skeletal trauma briefly define each type?
Typically, traumatic injury to bone is classified into one of four categories, defined by the trauma mechanism. A trauma mechanism refers to the force that produced the skeletal modification and can be classified as (1) sharp force, (2) blunt force, (3) projectile, or (4) thermal (burning).
How do you determine the age of a wound?
Total RNA of sufficient quality and quantity can be obtained using biological stains that are several months, even years, old [29–31]. Thus, the mRNA levels of inflammatory cytokines and wound-healing factors are assayed using the real-time polymerase chain reaction (PCR) to evaluate wound age.
What are the different types of injury according to site of application of force?
Three specific subtypes of sharp force injuries exist, as follows: stab wounds, incised wounds, and chop wounds.
What is a green bone response?
Timing of Injury Therefore, the perimortem interval (at or around the time of death) means that the bone is still fresh and has what is referred to as a green bone response, which can extend past death by several weeks or even months.
What are the 4 fracture classifications?
Although there are many types of bone fractures, there are four main categories a fracture usually falls under: displaced, non-displaced, open and closed.
What is wound in forensic science?
Forensically it is wound when there is damage of any tissue or organ irrespective of breach of continuity of the skin or mucous membrane.
What is Perimortem trauma?
Perimortem trauma refers to an injury occurring at or around the time of death. Because. of the properties of bone, the timing of injury is less precise when evaluating bone than. when evaluating soft tissue.
What are the classification of fracture?
Closed or open fractures: If the injury doesn’t break open the skin, it’s called a closed fracture. If the skin does open, it’s called an open fracture or compound fracture. Complete fractures: The break goes completely through the bone, separating it in two. Displaced fractures: A gap forms where the bone breaks.
What’s the difference between antemortem and perimortem?
Perimortem: at or near the time of death; in perimortem injuries, bone damage occurring at or near the time of death, without any evidence of healing. Antemortem: before death; bone damage in antemortem injuries shows evidence of healing.
