Flashcards in elbow - structure, function, anatomy Deck (37):
1

ulna articulates with

trochlea

2

motion at radioulnar joint?

pron/sup

3

motion at humeralradial joint

pron sup flex ext

4

motion at humeralulnar joint

flex ext

5

what is carrying angle

angle of the ulna in relation to the humeral shaft

6

borders of cubital triangle

pronator teres, brachioradialis

7

what lies in the cubital fossa (triangle)

brachial artery, median nerve, musculotaneous

8

purpose of the radial head

gliding, rotation, enhances stability

9

Anterior band of the anterior UCL resists what motion?

valgus forces till 90 degrees of flexion

10

Posteior band of the anterior UCl resists what motion?

valgus force beyond 60 degrees

11

posterior bundle taut during

flexion above 90 degrees

12

annular ligament resists

internal rotation

13

interosseus membrane stabilizes against

axial force applied to the wrist

14

brachiale is a prime flexor in

pronation

15

median nerve innervates

wrist flexors and pronators
runs through cubital fossa

16

ulnar nerve innervates what structures

sensory and motor innovators of the hand

runs through arcade of struthers, medial side of elbow, past hook of hanmate, tunnel of guyon.

17

radial nerve innervates

motor control - wrist extensors and supinators
posterior aspect of humerus, crosses over to lateral aspect of elbow

18

Dermatomes

look em up

19

look at special tests!

now

20

flex/ext - plane and axis

sagital plane, coronal axis

21

pron/sup plane and axis

transverse plane, longitudinal axis

22

MOI elbow dislocation

Foosh, landing on immovable oject, axial force through arm with slight flexion

23

Elbow terrible triad

posterior dislocation, fracture of radial head, fracture of coronoid

24

MOI elbow fractures

fall on flexed elbow, hyperextension

25

radial head fracture MOI

foosh

26

elbow sprain MOI

strain placed on ligaments with a flexed elbow

27

UCL MOI

stress secondary to valgus over loading, force delivered to lateral elbow

28

Biceps tendon rupture

males over 40, smokers, eccentric loading of the biceps when elbow is flexed to 90

29

OCD's of the capitellum

compression, valgus extension overload, throwing

30

numbness on dorsal hand

compression of ulnar nerve at elebow

31

numbness on palmar hand

compression of ulnar nerve at wrist

32

Radial nerve MOI

deep lacerations

33

test radial nerve with

tinel's sign

34

carpal tunnel syndrom

median nerve

35

pronator teres syndrom

median nereve

36

volkmann's contracture

compartment syndrome

37

valgus extension overlaod

attenuation of the anterior band of the UCL
