Flashcards in Mechanisms and Characteristics of Sports Injuries Deck (50):
1

tearing =

laceration

2

tearing/ripping=

avulsion

3

penetrating=

puncture

4

breaking point of tendon injuries is equal to or more than ____

6-8%

5

reflex reaction caused by trauma of the musculoskeletal system

muscle spasms

6

rigid muscle contraction that lasts a period of time

tonic

7

alternating involuntary muscular contraction and relaxation in quick succession

clonic

8

fluids that collect in muscles during and after exercise are absorbed into the blood stream at a slow rate

muscle stiffness

9

inflammation of synovial sheath; crepitus; chronic- locally thickened

tenosynovitis

10

myositis ossificans occurs in a muscle over a bone

ectopic calcfication

11

abnormal shortening of a muscle tissue

contracture

12

joint that is immovable

synarthrotic

13

slightly movable joint

ampiarthrotic

14

freely movable joint

diarthrotic

15

primary injury in ligaments?

viscoelastic tissue properties; constant compression causes deterioration, intermittent compression increases strength; chronic inflammation causes shrinkage of collagen fibers

16

an organ will adapt itself structurally to an alternation, quantitative of function

rouxs law of function adaption

17

part of nasal septum, larynx, trachea, bronchi, articular ends of bones

hyaline or articular cartilage

18

vertebral disks, pubic symphysis and menisci of knee joint

fibrous

19

external ear and eustachian tube

elastic

20

ellipical convex head in an elliptical concave socket

ellipsoidal; wrist

21

reciprocally concavoconvex

saddle; carpometacarpal joint of thumb

22

small amount of gliding back and forth or sideways

gliding; joints b/w carpal and tarsal bones, intervertebral joints

23

states that the joint capsule, the muscle moving in that joint, and the skin overlying the insertion of the muscle have the same nerve supply

Hilton's law

24

- a disjointing of two bones parallel to one another or
- rupture of a solid joint (pubic symphysis)

diastasis

25

degenerative changes in the ossification centers of the epiphyses of bones

osteochondrosis

26

degeneration of the articular or hyaline cartilage from repeated trauma;
s/s pain may be localized or generalized to joint; pain by friction; joint cracking

osteoarthritis

27

sudden irritation can cause acture bursitis; overuse of muscles or tendon or compression

bursitis

28

dense, white fibrous membrane covers long bones

periosteum

29

often in flat bones; caused by falling and striking body part on unyielding surface or by being hit with a hard object

depressed fracture

30

incomplete break in bones that have not completely ossified; often occurs in convex bone surface while concave surface remain intact

greenstick fracture

31

caused from fall from a height. require immediate spliting by AT and traction by physician to ensure normal length of injured limb

impacted fracture

32

bone splits along its length; often result of jumping and stress directs up long axis

longitudinal fracture

33

s-shaped separation; common in football and skiing

spiral fracture

34

occur when one end of the bone receives sudden torsion while other is fixed or stabilized

oblique fracture

35

two bony fragments have a saw tooth, sharp edged fracture line; usually caused by direct blow

serrated fracture

36

occurs in a straight line at right angles to the bone shaft; caused by direct blow

transverse fracture

37

greater than or more fragments at fracture site. caused by hard blow or fall. hard to heal cause of fragments

comminuted fracture

38

occur two the wall of the eye orbit as a result of a blow to the eye

blowout fracture

39

occur on side opposite to the point at which trauma was initiated; fracture of skull

contrecoup

40

separation of a bone fragment at an attachment of ligament or tendon; sudden, powerful twist

avulsion fracture

41

separation of physis

type 1

42

separation of growth plate and small part of metaphysis

type 2

43

fracture of physis

type 3

44

fracture of portion of physis and metaphysis

type 4

45

crushing force; growth deformity

type 5

46

occurs when a reduced amount of blood is available to the circulatory system;fatigue, exposure to heat/cold, dehydration or illness

shock

47

signs: low BP ( less than 90 systolic), rapid and weak pulse, drowsy sluggish, shallow and rapid respiration, skin is pale , cool and clamy

shock

48

treatment: maintain body temp, raise legs 8-12 inches off the ground

shock

49

rapid strong heart beat may indicate

heat stroke

50

dimensions for crutch fitting:

6 inches anteriorly, 2 inches laterally; 2-3 finger widths in arm pit, 30 degrees of flexion; 12-15 inches ahead while walking
