Flashcards in 02 Elbow Deck (40):
1

landmark for lymph nodes

medial and lateral supracondylar ridge

2

Where is the sublime tubercle and what does it do?

- where the UCL attaches at distal end
- creates isometricity

3

________ can form on olecranon process or foss, causing posterior pain

osteophytes

4

Most common site on the elbow for itis/osis

lateral epicondyle

5

What is 1 body inch distal to the lateral epicondyle?

radiocapitellar joint

6

What is significant about the radiocapitellar joint?

radial head is a common site for OA changes or OCDs

7

What is OCD?

osteochondral defect

8

The UCL is _____ to the sublime tubercle

medial

9

UCL is susceptible to _____

sprains

10

How is the annular ligament commonly injured?

- in children
- radial head subluxation - distraction force

11

Function of the annular ligament

stabilize radial head

12

characteristic of olecranon bursitis

it's as big as a grapefruit

13

What is the significance of the palmaris longus?

- absent in 15% of the population
- commonly harvested for UCL reconstruction

14

What is the combo of brachioradialis, ECRL, and ECRB called?

mobile wad of 3

15

superficial extensors

- ECRL
- ECRB
- extensor digitorum
- ECU

16

What's in the antecubital fossa?

- lacertus fibrosus
- brachial artery
- median nerve

17

What muscles outline the antecubital fossa?

- brachioradialis
- pronator teres

18

goniometry norms
extension/flexion

0-150˚

19

goniometry norms
pronation

0-80˚

20

true axis measurement

- line up gonio with 3rd metacarpal (true axis) and line up moveable arm with 2nd metacarpal

21

parallel axis

move gonio to the side of the hand to measure (Davies says it's more accurate)

22

goniometry norms
supination

0-80˚

23

goniometry norms
carrying angle

males: 0-5˚
females: 10-15˚

24

What is usually the hardest movement to regain after injury?

supination

25

What is the carrying angle?

valgus angle at the elbow

26

How do you note negative values?

5˚-0˚-150˚
or
for less ROM: 0˚-5˚-150˚

27

MMT for flexion
positions and muscles

- supinated: biceps
- neutral: brachioradialis
- pronated: brachialis

28

What are the MMT for the elbow?

- flexion (biceps, brachioradialis, brachialis)
- extension (triceps)
- pronation
- supination

29

2 techniques for MMT pronation/supination

- handshake technique
- grasp forearm

30

Why would you choose to not use the handshake technique for MMT?

a patient with intrinsic hand problems

31

close packed position of the elbow

32

Why do you go to 30˚ flexion for the elbow stability tests, what are you doing?

isolating the posterior band of the capsule

33

Which test was developed by patients?

- milking tests

34

If a patient can't do the milking test, what do you have to do?

- grab thumb and place valgus force
- can put them at 90˚ abduction

35

What are the elbow neuro tests?

- Tinel's ulnar nerve test
- elbow flexion test
- pronator teres syndrome test
- pinch grip test (testing ant. interosseous br of median n.)

36

Tinel's ulnar nerve test signifies inflammation if:

tingling goes distal

37

pinch grip test results

- normal = tip to tip
- + if using adductor to substitute

38

What should you see with the valgus stress test at 30˚ as compared to 0˚?

should have more motion

39

Why are we not doing the valgus stress test at 90˚?

too much shoulder involvement

40

What is the order of elbow stability tests that you'd do in the clinic?

1. valgus stress test at 0
2. valgus stress test at 30
3. varus stress test at 0
4. varus stress test at 30
5. milking tests
