Q

How common is a Bankhart lesion in shoulder dislocation

A

85%

28
Q

What ligament may have excessive force on it with SLAP, and why?

A

anterior band of inferior GH ligament

due to decreased ability to withstand rotational forces

29
Q

What causes primary impingement?

A

compression of RC tendons between humeral head and arcomion, CA ligament, or AC joint

30
Q

What ROM is force against acromion highest?

A

85 and 136 degrees

31
Q

What type of acromion is most commonly associated with primary impingement

A

type 3 (hooked, 70%)

32
Q

What causes secondary impingement

A

instability of GHJ leading to increased superior translation of humeral head

33
Q

What aspect of throwing puts rotator cuff at risk?

A

repetitive, heavy, eccentric forces on posterior cuff

34
Q

What is undersurface impingement?

A

pinching of supraspinatus/infraspinatus tendons at humeral head and posterior/superior glenoid rim.

35
Q

What demographic usually gets undersurface impingement?

A

young athletes

36
Q

what position puts a patient at risk for undersurface impingement?

A

90/90

37
Q

What positions of shoulder increase pressure on posterior glenoid with throwing?

A

increased horizontal abd

38
Q

Do submaximal isometrics increase perfusion and latent hyperemia

A

Hell yeah they do

39
Q

What muscles force couple to allow for scapular upward rotation and stabilization during elevation?

A

SA, LT

40
Q

Should patients with secondary impingement/tensile overload have accessory mobilizations performed?

A

Nope, may increase laxity

41
Q

Should patients with primary impingement have accessory mobilizations performed?

A

Hell yeah, mob that shit

42
Q

What position should posterior capsular mobilizations be performed?

A

30* elevation with IR

43
Q

Which stretch led to more IR gains, cross body or sleeper?

A

cross body

44
Q

What effect does towel roll for tband exercises have?

A

10% increase in infraspinatus activity

adduction increases SA space

45
Q

For RC strengthening, what % of maximal effort maximized infraspinatus activity compared to deltoid

A

40%

46
Q

What is normal ER/IR at GHJ

A

66%

47
Q

Which side of the rotator cuff will tears associated with SAI be located?

A

superior (bursal)

48
Q

What side of the RC will tears associated with GHJ instability or increased tensile loads?

A

undersurface (articular)

49
Q

What leads to bursal side RC tears?

A

SAI

50
Q

What leads to undersurface RC tears

A

GHJ instability, increased tensile loads

51
Q

What benefits does scapular plane have for early RC rehabilitation?

A

little stress on anterior shoulder due to anterior capsular laxity in this position

bony congruity

52
Q

What grades of AC joint injury can typically be treated conservatively?

A

Grades 1-3

53
Q

What diseases increase risk for frozen shoulder

A

thyroid, diabetes

54
Q

What causes frozen shoulder?

A

elevated cytokine levels leading to exaggerated inflammatory and fibrosis response

55
Q

Stage 1 frozen shoulder pain?

A

end range pain

56
Q

What is stage 1 frozen shoulder often mistaken for

A

SAI

57
Q

Stage 2 frozen shoulder

A

beginning of connective tissue changes leading to contracture

58
Q

Stage 3 frozen shoulder

A

mature adhesions

59
Q

What is a hallmark sign that differentiates frozen shoulder from rotator cuff tendinopathy?

A

passive ER loss in neutral

60
Q

Which muscle group will be relatively weaker in frozen shoulder compared to RC tendinopathy?

A

internal rotators

61
Q

Are high grade mobilizations significantly better for ROM gains with frozen shoulder when compared to low grade mobs?

A

No, only slight difference present

62
Q

What is the evidence for corticosteroids for frozen shoulder?

A

strong evidence for first 3-6 weeks for short term outcomes

63
Q

Why would performing a traditional TSA be inadvisable in a RC deficient shoulder

A

eventual glenoid loosening

64
Q

What elevation ROM is expected in shoulder hemiarthroplasty?

A

approximately 90-120 degrees

65
