Elbow Assessment Part 1

What is the primary ligament that resists valgus force at the elbow?

• Annular Ligament

• Radial collateral ligament

• Ulnar collateral ligament

• Interosseous membrane

Which elbow joint allows for both flexion/extension and pronation/supination?

• Humeroulnar

• Humeroradial

• Distal radioulnar

• Proximal radioulnar

Which muscle is responsible for true flexion of the elbow and does not assist in supination?

• Biceps brachii

• Brachialis

• Brachioradialis

• Anconeus

The most important stabilizing structure on the lateral side of the elbow is:

• Annular ligament

• Lateral ulnar collateral ligament

• Accessory lateral collateral ligament

• Radial collateral ligament

Which nerve innervates most of the wrist flexors and both pronator muscles?

• Median Nerve

• Ulnar Nerve

• Radial Nerve

• Axillary Nerve

Which ligament encircles the radial head and allows for pronation and supination?

• Radial collateral ligament

• Ulnar collateral ligament

• Lateral ulnar collateral ligament

• Annular ligament

Which muscle is commonly called the “beer drinking muscle” due to its role in elbow flexion

• Brachialis

• Brachioradialis

• Biceps brachii

• Anconeus

What is the close-packed position of the elbow?

• 10-20° and 60-90°

• Full extension

• 30-45° and >120°

• 0–20° and >120°

Match the muscle to its main action

• Elbow Flexion

• Terminal Elbow Extension

• Triceps

• Elbow flexion and supination

• Supinator

• Supination

• Brachialis

• Elbow extension

• Biceps Brachii
