Q

with downward rotation what happens to the inferior border and scap

A

inferior border goes medial and glenoid faces inferior

31
Q

with upward rotation of the scap what happens to the inferior border and glenoid?

A

the inferior border goes lateral and glenoid faces superior

32
Q

what muscles are responsible for the downward rotation of scap

A

rhomboid

33
Q

what muscles do upward rotation of the scap

A

serratus anterior and middle and lower trap

34
Q

what happens in normal arm elevation?

A

abduction and flexion > scap protracts & upwardly rotates > scap posteriorly tilts while humeral head ER

35
Q

why does the humeral head ER with arm elevation

A

to increase the subacromial outlet space

36
Q

when does the scap actively start to rotate?

A

30-40

37
Q

when does the scap begin to passively rotate?

A

60-70

38
Q

what is the overall motion ratio of the GH:scap

A

120:60 = GH:scap

39
Q

what is the scapulohumeral rythm?

A

how the scap and GH move in conjunction with one another

40
Q

after what deg. of abduction movement does the scapulohumeral ratio even out

A

at 120 deg.

41
Q

during abduction how does the scap tilt?

A

posteriorly: superior pole moves down and away and inferior pole moves up and forward

42
Q

describe the swivel affect of the scap when abducting?

A

before 90 the fossa shifts posteriorly and after 90 the fossa shifts anterior

43
Q

when a pt. has forward shoulder clinically they will present with

A

increase of protraction
not enough posterior tilt
not enough upward rotation

44
Q

what mm. are responsible for forward shoulders

A

weak serratus anterior and middle & lower trap

45
Q

apleys scratch test is used for

A

UE ROM

46
Q

anterior contralateral test the GH how?

A

horizontal flexion

47
Q

anterior contralateral test the scap how

A

protraction and upward rotations

48
Q

the anterior ipsi-contralteral test GH how

A

ER and flexion

49
Q

the anterior ipsi-contralteral test scap how

A

protraction and upward rotation

50
Q

the posterior contralateral test the GH how?

A

IR and extension

51
Q

the posterior contralateral test the scap how?

A

retraction and downward rotation

52
Q

SICK scap stands for

A

scapula protracted
inferior border prominent
coracoid pain
kinesis altered

53
Q

setting the scap means what?

A

being able to hold the scap firmly against the rib cage for GH to have full strength

54
Q

what muscles are responsible for setting the scap?

A

middle and lower trap

serratues anterior

55
Q

SC joint: is it stable or unstable?

A

stable

56
Q

what is the degrees of motion of the SC?

A

2: vertical and horizontal

57
Q

as arm moves foward what happens to the SC joint?

A

it goes posterior

58
Q

what are the ligaments of the SC?

A

superior, anterior, posterior SC
costoclavicular
interclavicular

59
Q

vertical movement of SC

A

elevation and depression

60
Q

horizontal movement of SC

A

anterior/protraction

posterior/retraction

61
Q

the SC joint is restricted by which ligament and mm

A

the costoclavicular or subclavius mm.

62
Q

during flexion/extension how much conjunct rotation occurs?

A

30

63
Q

is the AC joint stable or unstable?

A

unstable

64
Q

ligaments of the AC joint

A

superior and deep AC joint
Conoid
Trapezoid

65
Q

when is the conoid ligament taught

A

retraction

66
Q

when is the trapezoid ligament taught?

A

protraction

67
Q

when does most movement of the AC jt. occur?

A

flexion/extension

68
Q

where do AC seperations or dislocation occur?

A

in the superior region

69
Q

what structures check the AC for sperations

A

delto-trapezoid apneurosis

70
Q

Grade 1 of AC seperation

A

partial tear of AC with no elevation

71
Q

Grade 2 AC seperation

A

ACpartial torn with partial tear of CC with slight elevation

72
Q

Grade 3 of AC seperation

A

complete tear or AC and CC

73
Q

what JT. is known as the horizontal stabilizer of the shoulder

A

AC

74
Q

what does 60 deg angulation refer to?

A

the anterior 30 deg of scap and the 30 deg posterior of the clavical making a 60 angulation between the scap and the acromium
