Q

what happens when an intact ligament is traumatically stressed?

A

avulsion fracture

17
Q

what is a tendinitis that leads to mineral deposits

A

calcific tendonitis

18
Q

in throwing, muscles exert a tremendous amount of force on the distal and proximal humeral epiphysis during the acceleration face, damaging the

A

radial head

19
Q

approximately 85% of all ankle injuries result from

A

inversion

20
Q

a contusion can penetrate the outer layer of the bone causing

A

periostitis

21
Q

the technical name for a total disunion between two articulatory processes is

A

luxation

22
Q

what are some common sites for stress fractures

A

tibia, fibula, metatarsal shaft, femur, ribs, humerus

23
Q

what features do all synovial articulations have in common?

A

have a capsule and ligaments
capsule is lined with a synovial membrane
opposing bone surfaces contain hyaline cartilage
joint space containing synovial fluid

24
Q

list the four progressively severe stress fractures

A

focal microfractures
periostel and end-steal response
linear fractures
displaced fractures

25
Q

muscles try to stabilize joints in what ways?

A

cross joint muscles assist in proper alignment

some attach to articulacy capsule and tighten it when stretched

26
Q

Which is more susceptible to n injury, muscle of its tendon? why?

A

a muscle because tears occur there and is the weakest between it and the tendon, and the weakest structure is damaged first

27
Q

what factors would you use in evaluating dislocations

A

loss of limb function
deformity
swelling and tenderness

28
Q

how to determine stress fracture of anterior leg pain

A

look for swelling, focal tenderness, and pain
