Question 8

Coracobrachialis

Answer 8

O: coracoid process
I: middle humerus
N: musculocutaneous
A: flex and adduct arm
Part of conjoined tendon
Musculocutaneous nerve pierces 6-8cm distal to coracoid process

Question 9

SC joint

Answer 9

Sternoclavicular joint uncommon site of info or dislocate

Question 10

Clavicle

Answer 10

subcutaneous bone, most common bone to fx

Question 11

Answer 11

acromioclavicular joint common site for shoulder separation or DJD/pain

Question 12

Acromion

Answer 12

landmark for shoulder…think injection/scope

Question 13

deltoid mm

Answer 13

can test mm function for axillary nerve motor function

Question 14

Trapezius

Answer 14

common site of pain, weakness/palsy = lateral winging

Question 15

Serratus anterior

Answer 15

weakness/palsy = medial winging

Question 16

Pectoralis major

Answer 16

rupture at humeral insertion => axillary fold defect

Question 17

cephalic vein

Answer 17

lies in deltopectoral fold

Question 18

Scapular spine

Answer 18

suprascapular nerve palsy => infra/supraspinatus mm wasting ==> spine becomes more prominent

Answer 19

portion thats wings w/ palsy

suprascapular nerve compressed in spinoglenoid notch

Answer 21

IS affected

Question 22

glenoid orientation

Answer 22

pear shaped, 5-7 degrees retroverted, 5 degrees superior tilt

Question 23

unfused acromion =>

Answer 23

os acromiale

Question 24

humeral head orientation

Answer 24

retroverted 35 degrees

Question 25

humerus anatomic neck

Answer 25

may result in osteonecrosis

Question 26

humerus surgical neck

Answer 26

common fx site in elderly

Question 27

humerus head/neck angle

Answer 27

130 degrees

Question 28

humerus bone growth

Answer 28

80% from proximal physis

Question 29

bicep tendon

Answer 29

in bicipital groove between gtr and lsr tuberosity

Question 30

clavicle facts

Answer 30

S shaped cylindrical bone
middle 1/3 narrowest w/o mm insertions
widens laterally
no true medullary canal
only link from UE to axial skeleton
most common fx; middle 1/3
1st to ossify, last to fuse
