Q

What are the 2 ligs that connects clavical to scapula and prevents rotation on eachother (what rot do each limit)

A
  1. Trapezoid (lat)- limits back rot of the clavicle
  2. Conoid (med)- limits forward rot of clacicle

(together called coracoclavicular)

Q

What makes up the costovertebral jt.

A
  1. head of rib to vert

2. Costotransverse- costal tubercle with transverse process

17
Q

What are the 2 psuedo jts of the shoulder

A
  1. Scapulo thoracic jt

2. suprahumeral space

18
Q

What happens in the 2nd phase of scapulo humeral rhythm (humerus, clavicle, ac jt, sc jt)

A

Humerus- abducted 30
Clavical- elevated 12-15 degrees no rot
Ac jt- increase of 10 degrees

19
Q

What happens in the 3rd pahse of scapulo humeral rythem (humerus/Scap throacic, clavicle, sc jt)

A

Humerus- to 90 (60 GH, 30 ST)
Clavical- to 30 no rot
sc- no change

20
Q

what happens in the 4th phase of scapulo hueral rhythem (humerus/Scap throacic, clavicle,)

A

full 180- (120 humeral, 60 scapular)

clavical rotates for this extra movement at scapulo clavical angle

21
Q

what are the 4 mm of the rotator cuff

A
  1. Infraspinatus
  2. supraspinatus
  3. teres minor
  4. subscapularis
22
Q

what are the downward rotators of the scapula (3)

A

lev scap
rhomboid minor
rhomboid major

23
Q

What are the upward rotators of the scapula (3)

A

upper traps
Lower traps depress med border
serratus ant pulls lower prtion of scap for

24
Q

what would ant capsul tightness result in

A
  1. Posterior humeral subluxation

2. Posterior glenoid wear

25
Q

What would posterior capsul tightness result in

A

Ant- sup humeral translation resulting in impingment sign

26
Q

what would loss of synchronous action of scapular stabailers lead to

A
  1. loss of muscle efficiency
  2. loss of humeral head depression
    3 loss of power of humeral pos mm
27
Q

If muscle fatigue in scapulo humeral balance what can it add stress on to

A

increased stress to static stabilizers (capsular ligs + labrum)

28
Q

What plane would the shoulder be in the most stability

A

in scapular plane

29
Q

What is the most frequent source of extrincic pain refering to the shoulder

A

Diaphram (phrenic n)

30
Q

What are the 4 visceral structures that refer to shoulder region

A

Diaphram
Lung
Heart
Gall bladder

31
Q

Where does the heart refer to in the shoulder

A

myocardial ischemia refer to left infraclavicular area
