Flashcards in 12_ Forearm, Wrist, Hand Deck (24):
1

What contributes to lateral elbow pain?

radial collateral ligament or the annular ligament about the radial head

2

what contributes to medial elbow pain?

ulnar collateral ligament

3

What is tennis elbow?

lateral epicondylitis

4

What is golfer's elbow?

medial epicondylitis

5

Describe nurse maids elbow.

dislocation of the radial head through the annular ligament against the humerus

6

What leads to medial epicondylitis (golfer's elbow)?

1. irritation to the common flexor tendon from excessive use.
2. Pain located to medial epicondyle and extends to medial forearm to the hand.

7

What will increase in pain, if pt has medial epicondylitis?

wrist flexion, hand grasping, pronation

8

What causes lateral epicondylitis (tennis elbow)?

irritation of common extensor tendon. Pain localizes to lateral epicondyle.

9

What is carrying angle?

the angle formed at the elbow (in anatomic position). Line along the long axis of humerus and along median forearm in valgus.

larger in woman

10

THe carrying angle >15 degrees is?

cubitus valgus

11

What happens as the carrying angle increases?

wrist moves to ADDuction

12

What happens as carrying angle decreases?

wrist moves to ABduction

13

what is the primary joint dysfunction at the elbow?

1. the olecranon (ulnohumeral)
2. radiohumeral joint is secondary

14

What are clinical presentation of Abducted ulna?

1. increased carrying angle.
2. olecranon prefers medial glide.
3. distal forearm prefers abduction

15

What are clinical findings of adduction with lateral glide of ulna

1. decreased carrying angle
2. distal forearm prefer adduction.
3. olecranon wants lateral glide

16

What muscles are involved in pronation?

pronator teres, pronator quadratus

17

What muscles are involved in supination?

supinator and biceps

18

What are the biomechanics of the radius on pronation?

1. pronation induces the distal portion of radius to move anteriorly.
2. this will cause the proximal portion to move posteriorly.

19

Pt that present with posterior radial head SD, could be expected to have had what preceeding the SD?

fall on outstretched hand, that was pronated

20

What happens during supination of the radius?

1. leads to anterior motion of the proximal portion of radius due to the properties of interosseous membrane.

21

What precipitating event would you expect to happen to induce a anterior radial SD?

fall backwards on flexed arm, and supinated hand.

22

What are major motions of the MCP joints?

flexion/ extension, Abduction/Adduction

23

What are minor motions of MCP, IP joints?

ant/post, medial/ lateral, internal/external rotation, traction/compression

24

SKier's thumb is also known as?

Ulnar collateral ligament tear of the PIP
