1

What does it mean to dislocate?

Go completely out of anatomic alignment

2

What does it mean to reduce?

Go back to anatomic alignment

3

What does it mean to subluxate?

Go partially out of anatomic alignment

4

What are the two types of glenohumeral disloations and which is the most common?

Anterior and Posterior Dislocation

Anterior is much more common
-probably 99%

Posterior
-electrocution, seizure, or intoxication

5

What is the best x-ray to view a shoulder dislocation?

axillary view

6

What tendonpathy is known as tennis elbow?

Lateral epicondyle pain
Tendon disease of extensor tendon origin (ECRB)

7

What tendonpathy is known as golfer's elbow?

Medial epicondyle pain
Tendon disease of flexor-pronator origin

8

What is nursemaid's elbow?

Dislocation of the radial head only, usually a low-energy pulling energy
Not as bad in kids than adults

9

The intrinsic muscles of the hand are responsible for:

Metacarpal phalangeal joint flexion,
Proximal interphalangeal joint extension,
Distal interphalangeal joint extension

10

What is a very important principle to remember when dealing with articular surface injuries?

The surfaces must be made perfectly straight in order to heal correctly
-if not, expect arthritis and joint pain to continue

11

What muscles of the rotator cuff are responsible for:
Elevation =
Internal Rotation =
External Rotation =

Elevation = supraspinatus and deltoid
Internal Rotation = subscapularis
External Rotation = infraspinatus and teres minor

12

a midshaft fracture of the humerus could easily cause which nerve injury?

radial nerve injury

13

a distal fracture of the humerus could cause what injury?

median or ulnar nerve injury

14

What nerve does carpel tunnel syndrome affect?

What are the general symptoms?

median nerve

-swelling of flexor tendon synovium
-sensation changes
-pain
-loss of thenar strength

15

An injury at the elbow to the posterior interosseus nerve would show what symptoms?

lack of thumb or finger extension

no change in sensation

16

An injury to the superficial branch of the radial nerve would cause what symptoms?

Sensation changes

no loss of motor strength
