Flashcards in Chapter 9- Mechanism and Characteristics of Sports Trauma Deck (28):
1

a fracture in which ligament tears off of part of the bone

avulsion fracture

2

the glenohumeral joint

ball and socket joint

3

this is a compression injury

contusion

4

this means tissue discoloration

ecchymosis

5

this is a resistance to a load

stress

6

this is deformation of a tissue

strain

7

a group of 3 or more bone fragments

comminuted fracture

8

this joins bone to bone

ligament

9

occurs after repeated joint sprains

capsulitis

10

inflammation of a muscles tissue

myositis

11

cause of osteochondrosis

aseptic necrosis

12

the elbow joint

hinge joint

13

muscle soreness that happens after 2-3 days

DOMS

14

a stress fracture is a

spontaneous fracture

15

this joins muscle to bone

tendon

16

what happens when an intact ligament is traumatically stressed?

avulsion fracture

17

what is a tendinitis that leads to mineral deposits

calcific tendonitis

18

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

radial head

19

approximately 85% of all ankle injuries result from

inversion

20

a contusion can penetrate the outer layer of the bone causing

periostitis

21

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

luxation

22

what are some common sites for stress fractures

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

23

what features do all synovial articulations have in common?

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

24

list the four progressively severe stress fractures

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

25

muscles try to stabilize joints in what ways?

cross joint muscles assist in proper alignment
some attach to articulacy capsule and tighten it when stretched

26

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

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

27

what factors would you use in evaluating dislocations

loss of limb function
deformity
swelling and tenderness

28

how to determine stress fracture of anterior leg pain

look for swelling, focal tenderness, and pain
