Elbow Joint
Medial Ligament orUlnar Collateral Ligament
3 components
Anterior Band
Anterior band is from the medial epicondyle of humerus to coronoid process on ulna
Elbow Joint
Medial Ligament orUlnar Collateral Ligament
3 components
Anterior Band
Posterior Band
Posterior band is from the sublime tubercle on the coronoid to the medial border of the olecranon

Lateral Ligament orRadial Collateral Ligament
Annular Ligament
The annular ligament attaches to the margins of the radial notch on the ulna
and surrounds the radial head and neck

Annular Ligament
Lateral Ligament
Lateral ligament is from Lateral Epicondyle on Distal Humerus
and fuses with Annular Ligament
