Mechanisms of sports trauma- Chapter 6 Flashcards
Compression (together) injury
- crushes tissue
- occurs when force can no longer be absorbed
- ex. fractures, contusions
Tension (apart) injury
force that pulls/stretches tissue
- stretching beyond yielding point
- ex. sprains(ligaments), strains(muscles, tendons), avulsion fractures (pulling away of bone)
Shearing injury
- force that moves across the parallel organization of tissue
- ex. blisters, vertebral disk injuries
Acute injury
-sudden onset
chronic injury
- usually come with slow progression over a long period of time
- repeated acute conditions
- poor performance techniques
transverse fracture
horizontal break
spiral fracture
torn in half by twisting force or impact
oblique fracture
angle break through the bone
comminuted fracture
“splinter” of bone into two or more fragments
greenstick fracture
one side of bone broke, the other bent
impacted fracture
broken ends jammed together by force of injury
contrecoup fracture
injury occurs on opposite side of hit
avulsion fracture (acute)
- ligamentous attachment pulled away from bone
- tendinous attachment pulled away
longitudinal fracture
occurs along or nearly along axis of bone
depressed fracture
bone depressed below surface
