Elbow Osteoarthritis

What is A?

• Epicondyles

• Humerus

• Ulna

• Humeral head

In elbow osteoarthritis, the most common location of joint space narrowing is typically seen in:

• Radial head & capitellum

• Olecranon & coronoid process

• Ulna-humeral joint

• Distal humerus & proximal radius

Which projection is the most suitable projection to examine elbow osteoarthritis?

• Lateral elbow

• PA Elbow

• Jones method

• Oblique elbow

To ensure proper positioning for an elbow view, which structure should be parallel to the IR?

• Radial tuberosity

• Olecranon fossa

• Humeral epicondyles

• Medial trochlea

What is the correction that is supposed to be done based on this image?

• Rotate the elbow internally until humeral epicondyles are parallel with IR

• Fully extend the elbow

• Rotate the elbow internally until humeral epicondyles parallel to IR

What is the structure labeled B?

• Olecranon fossa

• Lateral epicondyle

• Radial tuberosity

• Radius

Which of the following is a common radiographic feature of elbow osteoarthritis?

• Increased joint space

• Decrease joint space

• Presence of soft tissue calcification

• Complete obliteration of the joint space

Elbow osteoarthritis typically presents with uniform joint space narrowing across the entire joint.

• True

• False

In elbow imaging, which patient's position is recommended to visualize the narrowed joint clearly?

• Seated with arm extended

• Seated with arm flexed

• Prone

• Supine

All the anatomical structures stated should be clearly demonstrated in an AP Elbow projection EXCEPT:

• Olecranon fossa

• Radial tuberosity

• Humeral head

• 1/3 of radius & ulna
