What structure runs through the bicipital groove of the humerus? - ✔✔long head of biceps brachii
tendon
Describe how anisotropy relates to the angle of insonation. - ✔✔tendons must be imaged perpendicular
to sound beam in order to be imaged correctly
To better visualize a long axis view of the subscapularis tendon, the patient should be asked to
___________ rotate their arm. - ✔✔externally
--- - ✔✔---
Describe the articulation points of the radius and ulna at the elbow joint. - ✔✔pivot joint - medial
surface of radial head and radial notch of ulna
What are the attachment points for the annular ligament? - ✔✔anterior and posterior ulna
What muscles are typically visualized when performing an ultrasound examination of the elbow? -
✔✔biceps brachii, brachialis, and brachioradialis
Describe the boundaries and contents of the cubital fossa. - ✔✔superior - line connecting medial and
lateral epicondyles
medial - pronator teres
lateral - brachioradialis
superficial - median cubital vein
deep - brachialis and supinator
contents - (lateral to medial) - radial nerve, biceps brachii tendon, brachial artery, median nerve
, Where is the cubital tunnel and what structure passes in it? - ✔✔passage between medial epicondyle
and olecranon
ulnar nerve
Describe the anatomic movements associated with the elbow joint. - ✔✔supination
pronation (rotation of radial head within annular lig)
flexion
extension
Between what two muscles can the radial nerve typically be found in the cubital fossa? - ✔✔lateral -
brachioradialis
medial - brachialis
To image the common extensor tendon, what bony landmark on the humerus should be located? -
✔✔capitellum (articulating with radial head)
The annular ligament can be found surrounding what bony structure? - ✔✔radial head
The triceps brachii tendon can be found attaching to what bony process of the ulna? - ✔✔olecranon
To image the ulnar nerve, the transducer should be oriented posterior to what bony structure of the
distal humerus? - ✔✔ulnar groove on posterior aspect of medial epicondyle of ulna
How should the transducer be oriented to best visualize the biceps brachii tendon attaching to the radial
tuberosity? - ✔✔long axis toward the head
Describe how to position the transducer when imaging the ulnar nerve in the cubital tunnel. - ✔✔short
axis between medial epicondyle and olecranon
