Question 6

what are the 3 extra articular ligs at AC jojnt

Answer 6

Coracoacromial- from coracoid to summit of acromion

Trapezoid- from sup surface of coracoid to trapezoid line

Coroid- from base of caornoid to conoid tubercle of clavicle

Question 7

common dislocation of AJ joint from fall on shoulder- what ligg

Answer 7

costoclavicular ligiment is torn

Question 8

how can the ac joint dislocate w/o lig rupture

Answer 8

fall is more on elbow

-can be risk of overlap

what is the coracoacromial arch and what does it prevent

Answer 10

Acromion, coracoacromial lig, coracoid

-Prevents superior dislocation

Question 11

where is the triceps and biceps origin in relation to the GH joint capsul

Answer 11

triceps- outside

tendon of long- inside

Question 12

what isolates teh biceps tendon through the fibrous capsul

Answer 12

synovial membrane on both sides

first 60 degrees of abduction is done by what

after what is it done by

Answer 17

first 60- lat rot of scapula

after- rot of humerus at the shoulder jt

Question 18

what is dislocation of the GH jt caused by (and what is torn)

excessive extension and lat rot

fibrous capsul and anterosup labrum are torn

Question 19

labrum tears (what are they called)
sup
ant
post

Answer 19

sup- slap

Answer 20

suprascap and or axillary

Question 21

what is frozen shoulder caused by

Answer 21

fibrosis bw fibrous capsul, rotator cuff, delt and sub acromial bursea

Question 22

are the medial and lateral epicondyles within the fibrous capsul

Answer 22

no, so fracture of them wouldnt affect articulation

Answer 23

ant (strong)- med epi to coronoid margin
Obliq- olecranon and coronoid
post- med epi to coranoid

Question 24

2 ligs on lat elbow

Answer 24

1. radial collateral- lat epi to supinator crest and anular lig
2. annular lig- encurcles radius

Question 25

what is students elbow an inflamation of

Answer 25

subcutaneous olecranon bursitis

Question 26

what happens in pulled elbow and what is source of pain

Answer 26

force causes radial head to be displaced from annular lig

annular lig is source of pain

Question 27

how does an avulsion to medial epicondly occur and what nerve likely gets injured

Answer 27

fall w severe abduction

injury to ulnar n

Question 28

if the distal radioulnar synovial jt is inflamed how far can the inflamation travel

Answer 28

all the way to to distal forearm

Question 29

what does the radius articulate with

Answer 29

scaphoid and lunate

Question 30

Answer 32

fall on extended wrist, compress median nerve

Question 33
