A
  1. feel a pop
  2. usually lifting something when pop occurs
  3. bruising in upper arm

A

long head

36
Q

A distal rupture of the bicep involves which head?

A

both short and long, more urgent tx

37
Q

A
  1. traumatic

2. atraumatic

39
Q

What does TUBS stand for

Q

What is a typical hx for shoulder impingement (4)

A
  1. dull ache worse in evening
  2. pain generalized or lateral upper shoulder
  3. worst with overhead activity
  4. hurts to sleep on
42
Q

How do you perform Hawkins test and what is positive?

A

-pt sits with arm at 90 and elbow flexed at 90, physician stabilizes just distal to elbow joint and just proximal to wrist, then moves pt into internal rotation, positive test is pain in subacromial space

43
Q

Statement: The more curved the acromion the more likely for impingement on rotator cuff tendons below and less space for rotator cuff to run under bone

A

. just a statement to review

Yergasons Test

46
Q

What is the name of the test that results in pain with resisted flexion of the arm?

A

Speeds test

47
Q

What needs to tear in order for subluxation of the proximal tendon out of the groove on the shoulder to occur? (2)

transverse humeral ligament and usually the subscapularis tendon

48
Q

What action indicates Infraspinatus weakness?

A

ER weakness

49
Q

What action indicates supraspinatus weakness?

A

Empty can sign, forward elevation

50
Q
