        Above the coronoid fossa and radial fossa
        
        Distal attachment
        
        Ulna along margin of the coronoid process
        
        Proximal border of annular ligament

        Continuous with the collateral ligaments
        
        Posterior attachment
        
        Humerus along the upper edge of the olecranon
        fossa and back of medial epicondyle
        
        Psoterior and inferior margins of the neck of radius

- - - - Anterior:
        
        primary ligamentous restraint of valgus stress
      - Posterior:
        
        limits elbow extension
      - Transverse:
        
        keep the joint surface in approximation
      - Proximal attachment
        
        Anterior and inferior aspect of medial epicondyle
        
        Fused with common flexor tendon
        
        Fused with Humeral articular cartilage
        (edge of the trochlea)
        
        Distal attachment
        
        Coronoid process of Ulna
        
        Crosses distally on the medial and proximal ulna
        
        For stress distribution
        (broad proximally and distally tapers off)
  - - - Lateral ulnar collateral ligament
      - Annular ligament
      - Fan shaped
        
        Proximally from the
        inferior aspect of the lateral epicondyle
        
        Merge with annular ligament distally
        
        Reinforces the humeroradial articulations
        
        Protection against varus stress
        
        Assist to provide
        longitudinal distraction
        of the joint surfaces
      - Complex
        
        stabilizes against varus and supination
        
        Prevents subluxation of the humeroulnar joint
        
        Stabilizes radial head, stable base for rotation
- - - - Biceps Brachii
        
        Brachioradialis
  - - - Anconeus
