3 articulation among humerus, ulnar & radial bones

Humeroulnar joint

Humeroradial joint

Radioulnar joint


Flexion & extension of forearm

Reinforced by ulnar by ulnar collateral ligament

Injury: abnormal abduction of forearm

Humeroulnar joint


Flexion & extension of forearm

Reinforced by radial collateral ligament

Injury: abnormal adduction of forearm

Humeroradial joint


Pronation & supination of forearm

Reinforce by annular ligament

Radioulnar joint


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


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

Lateral epicondylitis (tennis elbow)


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

Median epicondylitis (golfer elbow)


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
