Radial Nerve in the Upper Arm Anatomical Correlation
|
Arrow = deep brachial artery and superficial veins of upper limb Arrowhead = radial nerve H = humerus |
|
Arrow = deep brachial artery and superficial veins of upper limb Arrowhead = radial nerve B = brachialis muscle H = humerus |
|
A linear 10 MHz probe over the upper 1/3 of the arm to visualize the radial nerve as it crosses the humeral shaft |
|
A. Transverse scan showing the radial nerve (yellow arrowhead) and the deep
brachial artery (red arrowhead). H = humerus |
|
B. The use of Color Power Doppler to identify the deep brachial artery
lateral to the radial nerve (yellow arrowhead). H = humerus |
Radial Nerve Above the Elbow (4-5 cm Above)
Anatomical Correlation
|
The solitary radial nerve appears predominantly hyperechoic at this region. B = brachialis muscle BR = brachioradialis muscle H = humerus R = radial nerve |
|
B = brachialis muscle BR = brachioradialis muscle Box = scan area H = humerus R = radial nerve |
Radial Nerve at the Elbow Anatomical Correlation
|
The radial nerve (arrowheads) becomes elliptical and linear as it divides into the superficial and deep branches. |
|
Arrowheads = branching of radial nerve BR = brachioradialis muscle H = humerus |
Radial Nerve Immediately Below the Elbow
|
The radial nerve (arrowheads) is visualized below the elbow lying immediately next to the radius bone. |
