Answer 0

“terrible triad”

Elbow dislocation + radial head fracture + coronoid process broken

Question 1

How do you fix a midshaft fracture?

Answer 1

needs to be repaired surgically

Question 2

What sometimes accompanies a proximal humerus fracture?

Answer 2

Shoulder dislocation

Question 3

What kind of fracture is this?

Answer 3

midshaft fracture

Question 4

The terms to describe elbow dislocations are based on…?

Answer 4

the position of the lower arm in regards to the humerus

Question 5

What type of elbow dislocation is this?

Answer 5

Posterior dislocation

Question 7

Answer 7

Falling on the shoulder

Question 7

What are the 5 types of elbow dislocations?

Answer 7

• lateral
• medial
• anterior
• posterior
• divergent

Question 8

How many views can you have for the elbow/lower arm?

What are they called?

Answer 8

4 views:

1. Anterior Posterior
2. oblique medial rotation (interior)
3. oblique lateral rotation (exterior)
4. lateral

Question 9

Which type of distal fracture usually results in an unstable elbow even after surgery ?

(may need an elbow replacement)

Answer 9

condylar

Question 10

Is this an AP and L view of a normal/abnormal humerus?

Answer 10

normal

Question 10

What other structures can be damaged in a midshaft fracture?

Answer 10

radial nerve and the deep brachial artery can be affected

Question 12

What type of fracture is this?

Answer 12

distal humeral fracture

Question 13

Due to the spongy nature of the humerus in elderly females, what injury can accompany a proximal humerus fracture?

Answer 13

Collapse & deformation of the bone (requires correction when fracture is treated)

Question 14

What is the usual cause of elbow fractures?

Answer 14

Fall on outstretched hand

Question 15

Elbow Anatomy: What structure of the humerus points medially in anatomical position?

(good directional indicator)

Answer 15

the Medial Epicondyle

Question 16

What are the 2 types of distal humeral fractures, and which is more severe?

Answer 16

1. supracondylar = above condyle (most common in children)
2. condylar fracture = on condyle (most severe)
   * - usually high impact, usually needs surgery*

Question 17

How are the views named for radiographing the elbow/lower arm?

(which direction is the ray coming from vs. where is the plate?)

Answer 17

named for the surface the ray hits first, and the surface articulating with the plate secondly.

• ex. if the posterior side of elbow is on plate, rays will hit anterior side first, then posterior.*
• = Anterior Posterior view (AP)*

Question 18

Where does a distal humeral fracture occur?

Answer 18

On the condyle or just superior to the concyle.

Question 19

How do you repair a fracture-dislocation injury in the elbow?

Answer 19

it requires surgical repair

Question 20

If the sergical neck is borken in a proximal humerus fracture, what other structures can be damaged?

Answer 20

auxiliary nerve and **posterior circumflex humeral artery **

Question 22

Answer 22

Elbow dislocation

+

radial head fracture

+

coronoid fracture

Question 23

What type of fracture is shown here?

Answer 23

distal humeral fracture

Question 24

Proximal humerus fractures are common in what genre of people? Why?

Answer 24

Common in elderly females - because of post menopausal osteoporosis
