Which articulation of the elbow is primarily responsible for elbow flexion and extension?

• humeroulnar joint

• humeroradial joint

• proximal radioulnar joint

• radiocarpal joint

Which of the following ADLs would be significantly limited by a loss of elbow flexion in the dominant UE?

• hygiene

• LB dressing

• self-feeding

• both hygiene and self-feeding

You are working with a patient with stiffness of the forearm that significantly limits their active forearm supination. Which of the following motions would compensate for this specific loss of forearm motion?

• shoulder abduction and internal rotation

• shoulder and elbow flexion

• shoulder adduction and external rotation

• contralateral trunk flexion and shoulder internal rotation

Which of the following structures provides the most medial stability to the elbow?

• ulnar collateral ligament

• radial collateral ligament

• annular ligament

• oblique cord

The humeroulnar joint is best described as what type of articulation?

• uniaxial pivot

• uniaxial hinge

• triaxial ball-and-socket

• biaxial pivot

For which of the following would the biceps brachii muscle be most active?

• unscrewing a light bulb overhead with your left hand

• using a screwdriver to tighten a screw with your right hand, with the arm at the side

• using a screwdriver to tighten a screw with your left hand, with the arm at the side

• unscrewing a light bulb overhead with your right hand

Which of the following would be most difficult for an individual who has a significant deficit in pronation of both forearms?

• lifting and carrying a large box

• self-feeding

• washing their hair

• typing on a standard keyboard

Laxity of the medical collateral ligament (MCL) of the elbow may contribute to which of the following?

• cubitus valgus

• cubitus varus

• elbow flexion contracture

• median nerve compression

Prolonged repetitive elbow flexion may contribute to tension and compression on the ulnar nerve at which elbow landmark?

• radial head

• olecranon

• cubital tunnel

• antecubital fossa

A FOOSH with the elbow extended would most likely cause which of the following at the elbow?
