Flashcards in MSK - Shoulder and Elbow Joint Deck (13):
1

What is the classification of the shoulder joint?

Ball and socket

2

What are the FIVE movements of the shoulder joint?

- Extension of upper limb backwards in sagittal plane

- Flexion of upper limb forwards in sagittal plane

- Abduction of upper limb away from the midline in the coronal plane

- Adduction of upper limb towards the midline in the coronal plane

- Medial and lateral rotation of the upper limb

3

What contributes to the stability of the shoulder joint?

- Rotator cuff muscles

- Glenoid labrum

- Ligaments that form the coraco-acromial arch

4

Name the FOUR rotator cuff muscles

- Teres minor

- Infraspinatus

- Supraspinatus

- Subscapularis

5

What is the glenoid labrum?

A fibrocartilaginous rim that attaches around the glenoid fossa which makes the socket deeper therefore increasing stability

6

What is the most prevalent injury to the shoulder joint?

The joint becomes dislocated anteriorly due to excessive extension and lateral rotation of the humerus

7

What is an implication of an anterior dislocation of the shoulder joint?

- Can cause damage to the axillary nerve

- Paralyses deltoid
- Loss of sensation to the regimental badge

8

What is the classification of the elbow joint?

Hinge Joint

9

What are the movements of the elbow joint?

- Extension of the forearm
- Flexion of the forearm

10

What contributes to the stability of the elbow joint?

- Enclosed in a capsule

- Radial collateral ligament (runs from lateral epicondyle to anular ligament

11

Name TWO common injuries to the elbow joint

- Dislocation (common in children)

- Epicondylitis (tennis/golfers elbow)

12

How can the elbow joint become dislocated? What happens as a result

- Fall on hand when elbow is flexed

- Drives distal end of the humerus through the anterior side of the joint capsule

13

How is epicondylitis caused? How do tennis elbow and golfers elbow differ?

- Inflammation of common tendonous origin due to overuse

- Tennis = lateral
- Gold = Medial
