Flashcards in Elbow Deck (37):
1

3 bones making up the elbow

-humerus
-radius
-ulna

2

strength of elbow (skel, musc, ligs?)

-skel: moderate
-ligs: strong
-musc: strong

3

bony landmarks on radius

-radial head
-radial tuberosity

4

bony landmarks on ulna

-olecranon process
-trochlear notch: artics w/ trochlear on hum
-coronoid process: below trochlear notch
-radila notch: artics w/ radial head

5

bony landmarks on humerus

-med/lat epicondyle
-capitulum: artics w/ radial head
-trochlear: med artics w/ trochlear notch
-olecranon fossa

6

3 articulations of elbow

-humero-ulnar jt: trochlear/trochlear notch and olecranon fossa/process
-humero-radial jt: capitulum/radial head
-radial-ulnar jt: radial head/notch

7

movements of elbow

-flex/extend
-pronate/supinate of radius and ulna

8

ligaments of elbow on lateral side

-annular lig: radila head -> radial notch
-lateral collateral lig: lat epicondyle -> blends into annular lig (weak)

9

ligaments of elbow on medial side

-medial collateral lig: 3 bands

10

3 bands of medial collateral lig of elbow

-anterior: med epicondyle -> med aspect of coronoid process
-posterior: med epicondyle -> medial olecranon
oblique: olecranon -> coronoid, not important for jnt stability

11

origin of felxor carpi radialis

med epicondyl

12

insertion of FCR

base of 2nd/3rd metacarp

13

origin of FCU

med epicondly/upper ulna

14

insertion of FCU

pisiform

15

origin of palmaris longus

med epicondyle

16

insertion of palmaris longus

transverse carpal lig

17

action of FCR/FCU/palamris longus

-flex

18

origin of pronator teres

med epicondly/ coronoid process

19

insertion of pronator teres

mid radial shaft

20

action of pronator teres

pronation

21

origin of ECR/ECU/supinator

lat epicondyle

22

insertion of ECR

2nd/3rd metacarp

23

insertion of ECU

5th metacarp

24

insertion of supinator

prox end of radial shaft

25

actionf of ECU/ECR/supinator

-extend
supin: supnate

26

8 injuries to elbow

-myositis ossification
-fracture
-dislocation
-strain
-sprain
-injury to ulnar nerve
-olecranon bursitis
-supracondylar FX

27

how to tell if elbow is dislocated

look for olecranon processa nd epicondyles and see if they line up

28

how do you treat elow strain

-ice,ROM
-gentle stretch
-strengthen when pain free
-surgery if necess

29

what is lat/med epicondylitis

inflammination of bones

30

valgus vs vargus stress

val: med stress = injury to lat side
var: lat stress - injury to med side

31

4 injuries to ulnar nerve

-contused by blow
-stretched by valgus force
-entrapped by scar tissue
-irritated by bone spurs

32

what is the mechanism of ollecranon bursitis

contusion

33

what is the mechanims of supracondylar fx

falling on outstretched arm

34

what does supracondylar fc lead to
-two

-dislocation in post = post deform
-volkmann ischemic contracture

35

waht are we concerned about in a supracondylar fx

-growth plates here
-rapid sweeling can cause entrapment of nerves / blood vessels

36

what is volkmann ischemic contracture (VIC)

-disturbance of blood and nerve transmition
-useless limb = claw hand
-wrist flex, MP jnt flexed, PIP/DIP flexed

37

how do you treat VIC

-spint
-ice
-examine nerve and blood supply to hand and nail beds
-immediate refferal
