Ms - Shoulder

Front 1

muscles/nerves that flex the shoulder

Back 1

pectoralis major-
nerves:
medial pectoral nerve (med chord)
lateral pectoral chord (lateral chord)

Front 2

muscles/nerves that extend the shoulder joint

Back 2

lats-
Nerve: thoracodorsal

Front 3

muscles that adduct the shoulder

Back 3

pec and lats together- flexion and extension are cancelled

Front 4

muscles/nerves that abduct the shoulder

Back 4

5,6
deltoid (axillary nerve)
superpinatus (suprascapular nerve)

Front 5

external rotators of the shoulder + innervation

Back 5

infraspinatus (suprascapular nerve)
teres minor (axillary nerve)

Front 6

medial rotator of the shoulder + innervation

Back 6

subscapularis (upper and lower subscapular nerves)

Front 7

contents of the humeral acromial space

Back 7

supraspinatus and bursa

Front 8

rotator cuff injury symptoms

Back 8

pain w/ overhead use of arm

Front 9

pain with shoulder adduction, pain lying on involved side-

Back 9

think AC separation

Front 10

what are the origins of the triceps?

Back 10

long head: infraglenoid tubercle of the scapula

other 2 heads: posterior humerous

Front 11

actions of the biceps brachii

Back 11

strong elbow flexor

supinator of forearm

Front 12

origins of 2 bicep heads

Back 12

long head: supraglenoid tubercle

short head: coracoid process

Front 13

3 fascets of greater tuberocity of humerus

Back 13

attachment for:
supraspinatus
infraspinatus
teres minor

Front 14

action/innervation of trapezius

Back 14

elevates and retracts the scapula (remember it inserts on the spine of scapula)

innervation: spinal accessory nerve (XI)

Front 15

muscles of scapula retraction

Back 15

rhomboids (dorsal scapular nerve)

traps (XI, C3,C4 cervical nerves)

Front 16

winging of scapula is the result of?

Back 16

weakness of the serratus anterior

Front 17

muscles responsible for scapular protraction

Back 17

serratus anterior (long thoracic nerve)

pectorialis minor (medial pectoral nerves)

Front 18

where do the pectorialis (major, minor) insert?

Back 18

minor-> scapula (coracoid process-scapular protraction)

major-> humerus- lateral lip of intertubercular groove

Front 19

Adhesive capsulitis

Back 19

"frozen shoulder" capsule stiffness- occurs spontaneously and will resolve on own

Front 20

Contracture of shoulder

Back 20

capsule gets tight, limits ROM
attributed to strength of capsule and old age

Front 21

origin/insertion/innervation of deltoid

Back 21

o- lat clavicle, acromion, spine of scapula

i- deltoid tub of humerus

inn- axillary nerve

Front 22

2 things to consider in full shoulder abduction

Back 22

glenohumeral joint (the majority of the abduction occurs here)

after the first 30deg of abd, there is an upward rotation of the pectoral gurdile

Front 23

what is 'pinched' in shoulder impingement

Back 23

subacromial bursa and r.cuff (supraspinatus)

Front 24

impingement treatment

Back 24

avoid overhead use (decreases size of bursa)
strengthen stabilizers (traps, seratus ant)

Front 25

what 2 factors contribute to 180deg of shoulder abduction and in what proportions

Back 25

120deg- glenohumeral joint

60deg- scapular rotation

Front 26

within 60 deg of scapular rotation, what accounts for the first part of the movememt vs second

Back 26

1st- elevation of sternoclavicular joint

2nd- motion at acromioclavicular joint

Front 27

what 2 muscles are involved in scapular rotation (for shoulder abduciton)

Back 27

lower traps, serratus anterior

Front 28

bankart lesion

Back 28

torn labrum- usually from repeat dislocations

Front 29

sprengel's shoulder

Back 29

congenital fixation of scapula

Front 30

secondary impingement of shoulder

Back 30

rotator cuff weakness-> deltoid pulls humeral head upward and this pinches the supraspinatus tendon and subacromial bursa

Front 31

tx for impingement

Back 31

avoid overhead use
strengthen/stabalize scapula: traps/ serratus anterior

Front 32

Grade I AC separation

Back 32

AC damage-> sore, no long term effects

Front 33

Grade II AC separation

Back 33

tears AC joint- long term problems

Front 34

Grade III AC separation

Back 34

tears in coracoclavicularis AND AC

Front 35

Grade IV AC separation

Back 35

lateral clavicle dislocation - surgery

Front 36

shoulder deformity (step off)
pain with adduction
pain lying on involved side

Back 36

AC separation

Front 37

nerve to be worried about in shoulder dislocation

Back 37

axillary- (deltoid and teres minor)

Front 38

chronic shoulder stiffness, think

Back 38

adhesive capsulitis
