Flashcards in Elbow Complex Deck (20):
0

What is the structure of the elbow?

Compound joint
Stable bony arrangement

1

What is the carrying angle and why is it formed?

5-20 degrees
Trochlea of the humerus extends further distally than does the capitulum

2

What is the flexible ROM at the elbow?

145 degrees

3

How many joints make up the elbow complex? What are they called?

3
Radio-humeral
Superior radio-ulnar
Humeral-ulnar joint

All surrounded by loose capsule

4

What makes up the humero-ulnar joint? What plane is it in?

Hinge joint between trochlear notch and trochlea of humerus

Not in ant-post plane and so carrying angle in extension/sup formed

5

What does the semi lunar joint do?

Prevents lateral movement in humero-ulnar joint

6

What prevents lateral movement at humero-ulnar joint?

Semi lunar notch ulna

7

Anatomy of the radiohumeral joint?

Limited ball and socket hinge joint

8

How is the HOR held in the radial notch?

Annular ligament

9

Structure of radio ulnar joint?

Covers 80% of radial head
Thicker posteriorly > ant

10

What does the radio ulnar joint allow?

Together allow supination and pronation

11

What are the four major ligaments of the elbow?

Ulnar collateral
Radial collateral
Annular
Quadrate

12

What makes up the ulnar collateral ligament?

Anterior oblique band
Posterior band
Intermediate band

13

Where is the anterior oblique band?

Anterior medial epicodyle to coronoid process

Ulnar nerve crosses this section

14

Where is the posterior band of the ulnar collateral ligament?

Posterior medial epicodyle to coracoid process

15

What does the ulnar collateral ligament do?

Resists abduction force

16

What levels is the ulnar nerve, where is it in the brachial plexus?

C8-T1
Part of medial cord of the brachial plexus

17

What is the path if the ulnar nerve?

Descends on the posteromedial aspect of the humerus
Travels through cubital fossa at elbow
Enters the anterior (flexor) compartment of the forearm through the two heads of FCU and runs alongside the ulna

18

What cord/s of the brachial plexus form/s the median nerve?

Lateral and medial

19

What do the lateral and medial cords of the brachial plexus form?

The median nerve
