Radial Nerve:
- Discussion:
- superficial or sensory branch passes downward emerging dorsally from
beneath
Brachioradialis
tendon about 5 cm proximal to radial
styloid; they lies just deep to the superficial veins;
- just proximal to the wrist, several branches fan out to provides sensory
innervation to dorsal radial aspect of hand;
- superficial branch innervates the dorsal aspect of the first web space
& hand as far as the middle of the ring finger and as far distally as the
proximal interphalangeal joint;
- Nerve Block:
- superficial branch of the radial nerve is blocked three fingerbreaths
above the radial styloid;
- transverse wheal will be raised subcutaneously over a radial side
of the distal forearm;
- starting at dorso-radial aspect of wrist, continuous subQ track of
anesthetic is laid down in order to block all sensory branches;
- approximately 10 ml of anesthetic is required, and upto 5-10 min are
necessary for this block to work;
