Flashcards in Elbow joint Deck (18):
1

What is the note carrying angle

Angle between ulna and humerus
170 degrees but is larger (lower angle ) in females

2

Origin of ulnar collateral ligament

Medial epicondyle

3

Attachment of ulnar collateral ligament

Coranoid process and olecrannon of ulna

4

3 bands of ulnar collateral ligament

Anterior (strongest) - cord
Posterior - fan
Oblique - deepens socket for trochlea

5

What side of the joint is the radial collateral ligament on

Lateral side
From lateral epicondyle and blends with anular ligament of radius

6

Where is the intratendinous bursae

Within tendon of triceps brachii

7

Where is the subtendinous olecrannon bursa
What does it do

Between olecrannon and the tendon of the triceps brachii
Reduce friction during Flexion and extension

8

Where is the subcutaneous olecrannon bursa

Between olecrannon and overlying CT

9

What is subcutaneous bursitis

Subcutaneous olecranon bursa becomes infected (it's very superficial) and inflamed
Can also be caused by repeated friction and pressure on the bursa

10

What is subtendinous bursitis

Inflammation of subtendinous olecranon bursa caused by repeated extension and flexion of forearm

11

What can be damaged in elbow dislocations

Brachial artery,
Median and ulnar nerves
Ulnar collateral ligament is usually torn

12

Where does radial nerve pass at the elbow

Anterior to lateral epicondyle

13

Where does the ulnar nerve pass at the elbow

Posterior to medial epicondyle

14

Articulations at elbow joint

Trochlear notch of ulna and trochlea of humerus,
Head of radius and capitulum of humerus

15

Where is the capsule weak

Anteriorly and posteriorly

16

How are elbow dislocations named

By position of ulna and radius relative to humerus

17

What age group are more prone to elbow dislocations
How do they commonly occur

Children
Falling on hand with elbow flexed

18

Are most elbow dislocations posterior or anterior
Why

Posterior
Distal humerus is usually displaced over weakest part of capsule which is the anterior side
