3 articulation among humerus, ulnar & radial bones

Humeroulnar joint

Humeroradial joint

Radioulnar joint

1

Flexion & extension of forearm

Reinforced by ulnar by ulnar collateral ligament

Injury: abnormal abduction of forearm

Humeroulnar joint

2

Flexion & extension of forearm

Reinforced by radial collateral ligament

Injury: abnormal adduction of forearm

Humeroradial joint

3

Pronation & supination of forearm

Reinforce by annular ligament

Radioulnar joint

4

Severe distal traction of the radius (yanking a child's arm) --> subluxation of radial head

SSX: flexed, pronated forearm held close to the body

Reduction: apply direct pressure posteriorly on the radial head while supinating & extending the forearm

Nursemaid elbow

5

Inflammation of common extensor tendon of the wrist where it originates on the lateral epicondyle of the humerus

Lateral epicondylitis (tennis elbow)

6

Inflammation of common flexor tendon of the wrist where it originated on the medial epicondyle of the humerus

Median epicondylitis (golfer elbow)

7

Damages the contents of cubical fossa:
- median nerve
- brachial artery
- biceps brachii tendon
- median cubical vein (superficial to bicipital aponeurosis)
- radial nerve (deep to brachioradialis muscle)

Supracondylar fracture of the humerus
