The Elbow Joint

Page 3: Elbow Anatomy - Fisiokinesiterapia• The radial head may be displaced forward, backward, or outward • Children under 5 are prone to subluxation of the radial head due to a “pulling”

Bones of the Elbow

Humerus- medial epicondyle- lateral epicondyle

RadiusUlna

- olecranon process

Page 4: Elbow Anatomy - Fisiokinesiterapia• The radial head may be displaced forward, backward, or outward • Children under 5 are prone to subluxation of the radial head due to a “pulling”

Joints of the Elbow

• Hinge joint• Composed of 3 articulations:

1. Humeroulnar joint2. Humeroradial joint3. Radioulnar joint

Page 5: Elbow Anatomy - Fisiokinesiterapia• The radial head may be displaced forward, backward, or outward • Children under 5 are prone to subluxation of the radial head due to a “pulling”

Motions

• Flexion/Extension• Supination/Pronation

Supination – palm upPronation – palm down

Muscles Affecting the Elbow

- Elbow Flexors1. Brachialis2. Biceps brachii3. Brachioradialis

- Elbow Extensors1. Triceps 2. Anconeus

Page 7: Elbow Anatomy - Fisiokinesiterapia• The radial head may be displaced forward, backward, or outward • Children under 5 are prone to subluxation of the radial head due to a “pulling”

Muscles Affecting the Wrist Joint

- Wrist Flexor-Pronator group1. Pronator teres2. Flexor carpi radialis3. Palmaris Longus4. Flexor carpi ulnaris

These muscles originate on the medial epicondyle of the humerus as a single tendon

Page 10: Elbow Anatomy - Fisiokinesiterapia• The radial head may be displaced forward, backward, or outward • Children under 5 are prone to subluxation of the radial head due to a “pulling”

- Wrist Extensors1. Brachioradialis – only muscle to extend from distal end of one bone to distal end of another2. Extensor carpi radialis longus3. Extensor carpi radialis brevis

These muscles originate on the lateral epicondyle

Ligaments of the ElbowUlnar Collateral Ligamentmedial side – connects humerus to ulna

Radial Collateral LigamentLateral side – connects humerus to radius

Annular LigamentSurrounds radial head/holds it tight to ulna

Injuries to the Elbow

Page 15: Elbow Anatomy - Fisiokinesiterapia• The radial head may be displaced forward, backward, or outward • Children under 5 are prone to subluxation of the radial head due to a “pulling”

Elbow Dislocation

• Usually occur as a result of a fall on an outstretched arm

• May be associated nerve or vascular injury• Usually dislocates posteriorly• Anterior Dislocations – very rare

Possible olecranon fractureMedial and Lateral dislocations are rare

Page 18: Elbow Anatomy - Fisiokinesiterapia• The radial head may be displaced forward, backward, or outward • Children under 5 are prone to subluxation of the radial head due to a “pulling”

• Divergent Dislocationthe forearm bones are separated and the humerus slips between them

Dislocation of the Radius

• The radial head may be displaced forward, backward, or outward

• Children under 5 are prone to subluxation of the radial head due to a “pulling” on the forearm Pulled elbow or Nursemaid’s arm

Medial Epicondylitis

- “Little League Elbow”- Medial elbow pain and

pain with flexion of the wrist flexor muscles

- May see an avulsion of the medial epicondyle

Page 23: Elbow Anatomy - Fisiokinesiterapia• The radial head may be displaced forward, backward, or outward • Children under 5 are prone to subluxation of the radial head due to a “pulling”

Lateral Epicondylitis

- “Tennis Elbow”- Caused by excessive

wrist extension, especially with a clenched fist

- Pain over outer part of the elbow

Olecranon Bursitis

• A collection of fluid in the olecranon bursa that covers the posterior tip of the elbow. Is the result of direct trauma to the elbow.l
