Flashcards in The shoulder Deck (13):
1

4 joints of the shoulder

AC joint
sternoclavicular joint
glenohumeral joint
scapulothoracic articulation

2

subscapularis

attaches to the lesser tuberosity
innervated by the upper and lower subscapular nerves

3

supraspinatus

attaches to the greater tuberosity
innervated by the suprascapular nerve

4

infraspinatus

attaches to the greater tuberosity
innervated by the suprascapular nerve

5

teres minor

attaches to the greater tuberosity
innervated by the posterior branch of the axillary nerve

6

the relevance of the neck in shoulder problems

its the joint above
neck and shoulder pain can be felt in the same place
brachial plexus

7

bones of the neck

7 cervical spine
lordosis

8

rotation of the head

mainly performid in the atlantoaxial segment (C1/2)
the odnoid peg acts as axis of rotation
stabilised by the transverse liganment

9

the brachial plexus

5 roots in the ventral rami of spinal nerves
3 trunks (superior, middle and inferior)
3 anterior divisions
3 posterior divisions
3 cords (lateral, posterior and medial)
5 terminal branches (musculocutaneous, axillary, radial, median, ulnar)

10

terminal branches of the brachial plexus

musculocutaneous - C5,6,7
axillary - C5,6
radial - C5,6,7,8,T1
median - C5,6,7,8,T1
ulnar - C8,T1

11

subachromial impingement

irritation of the sub-acromial bursa or tendons of the rotator cuff, causing pain
presents with painful arc and restriction of function

12

frozen shoulder

adhesive capsulitis
idiopthic
diabetes - increases risk, more aggressive, takes longer to resolve
CVA, trauma, surgery, antiretrovirals are all risk factors

13

3 phases of frozen shoulder

Freezing - pain, worsening movement, lasts up to 9 months
Frozen - pain improves, movement limited, lasts up to another 9 months
Thawing - no pain, movement improves, can take up to 2 years
