What’s degloving?

105
Q

Caused when a portion of the skin is

caught on a sharp object while the body is moving away from the object and a flap of skin is removed

106

Most commonly occurs in industrial

settings with rotary tools or with ejectionsfrom a motor vehicle

107
Q

Most common injuries are getting

fingers caught in a closing door or feet run over by car.

A

Crush wound

108
Q

Occurs when a heavy object falls onto a
portion of a person’s body, splits the skin andmay even shatter or tear underlying
structures.

A

Crush wounds

109
Q

sharp pieces of bone penetrate and tear surrounding soft tissue &skin which created an open wound

A

Open fracture

110
Q

Most likely to occur with high energy injuries,

more superficial bones, and among the elderly.

A

Open fracture

111
Q

Characterized by a
slice wound created by a sharp object
which leaves
straight/even edges

A

Cuts/incisions

112
Q

3 basic mechanisms of injury for lacerations

A

Shearing
Tension
Compression

113
Q

Shearing

A

Small amount of force on a small area which typically results in minimal cell injury due to the sharp
instrument

114
Q

High amount of force at an angle with a blunt object which tears skin with significant tissue damage (i.e.grazing injury)

A

Tension MOI for laceration

High force at makes direct

perpendicular contact causing jagged/shredded wound edges and severe tissue damage (i.e. punch)

A

Compression MOI for laceration

116

High velocity projectiles (3000 ft/sec)
create negative pressure waves known as ? behind the bullet which
