What type of joint is the elbow joint?
Hinge joint
Flexion and extension
What is the most common forelimb joint involved in lameness?
Elbow
Name the ligaments supporting the elbow
Lateral collateral
Medial collateral
Annular
Location of lateral collateral ligament
Lateral epicondyle to lateral radial head and lateral ulna
Location of medial collateral ligament
Medial epicondyle to medial radial head
Location of annular ligament
Encircles radial head and attaches to the coronoid process
Name the three main articulations of the canine elbow joint
Humeroradial
Humeroulnar
Proximal radioulnar
Which articulation of the canine elbow joint bears the most weight?
Humeroradial
What is the role of the humeroulnar articulation of the elbow joint?
Resist lateral movement
What is the role of the proximal radioulnar articulation?
allows rotational movement of antebrachium
What do the three main articulations of the canine elbow joint share?
One synovial space
What can the elbow joint synovial space be divided into and by what?
Divided into lateral and medial compartment
By the trochlear notch
Which compartment of the elbow joint is most problematic and why?
Medial compartment due to the medial coronoid process
Name the three main areas of the elbow joint
Trochlear notch
Medial coronoid process
Olecranon
Name the three areas of elbow joint incongruence
Trochlear notch misshapen
Radius and ulna length discrepancy
Radial incisure
