Superficial radial nerve. The superficial radial nerve, also known as the superficial branch of the radial nerve, is a sensory cutaneous nerve that arises from the radial nerve. It supplies the skin on the dorsum of the hand as well as providing articular branches to joints in the hand . sensory function to the ulnar half of the dorsal thumb, dorsal index, long, and radial half of the ring finger. Originates from the radial nerve proper at the level of the radiocapitellar joint. runs distally in the forearm underneath the brachioradialis, lateral to the radial artery Course: The radial nerve branches into the superficial branch and deep branch, also known as the posterior interosseous nerve, in the deep posterior proximal compartment of the forearm. The superficial branch continues distally and arises superficially between the brachioradialis tendon and the extensor carpi radialis longus tendon within the mid-forearm Anatomy of Superficial Radial Nerve. Pure sensory nerve; Radial nerve bifurcates in the proximal forearm to give rise to superficial radial nerve (SRN) and posterior interosseous nerve (PIN) SRN travels deep to the brachioradialis and lies on the undersurface of the muscle; It emerges between brachioradialis and ECRL in the distal third forearm, to become superficial (under the skin
The superficial branch of the radial nerve is widely separated from the radial artery in the upper one third of the forearm, closely related to radial artery in the middle third of the forearm, and in the lower third, it descends in the forearm under the tendon of brachioradialis. It crosses brachioradialis to enter posterior of forearm near the back of the wrist and supply dorsum of hand Radial nerve (anterior view) At the level of the elbow, the nerve then passes into the supinator muscle, where it divides into a deep and superficial branch: The deep branch becomes the posterior interosseus nerve, and descends down the posterior forearm, to supply all of the wrist extensor muscles
Superficial radial nerve anatomy The superficial sensory branch of the radial nerve is purely sensory, runs under cover of the brachioradialis in the forearm. The superficial branch of the radial nerve passes along the front of the radial side of the forearm beneath the brachioradialis muscle Wartenberg's Syndrome is described as the entrapment of the superficial branch of the radial nerve with only sensory manifestations and no motor deficits. In this condition,the patient reports pain over the distal radial forearm associated with paresthesias over the dorsal radial hand.This should not be confused with Wartenberg's Sign which refers to the slightly greater abduction of the. superficial branch radial nerve; dorsal digital branch; Origin: Radial nerve originates from the posterior cord of the brachial plexus (C5-T1) behind axillary artery; Course: Posterior wall axilla. courses on the posterior wall of the axilla (on subscapularis, latissimus dorsi, teres major) 3 Branches in axilla. posterior cutaneous nerve of the ar The radial nerve runs down the underside of your arm and controls movement of the triceps muscle, which is located at the back of the upper arm. The radial nerve is responsible for extending the..
Surgical exploration revealed a fusiform hard swelling of the superficial sensory branch of the radial nerve. The neuroma was in continuity with the nerve, having twice the diameter of the nerve proximal to it. Resection of the neuroma created an unbridgeable gap of 2.5 cm between proximal and distal remnants of the nerve . Sensory: Dorsolateral hand & 1st 3 digits; May overlap with: Dorsal ulnar cutaneous nerve; Posterior interosseus nerve (Deep branch): Extensor carpi radialis brevis & Supinator.

The mean distance from the first major branching point of the superficial radial nerve to the radial styloid were 4.8 ± 0.4 cm The superficial radial nerve passes superficial to the supinator muscle. It is covered anteriorly by the brachioradialis. Recurrent vessels of the radial artery cross superficial and deep to these radial nerve branches. The posterior interosseous nerve courses in a dorsoradial direction in the proximal forearm
Superficial radial nerve injury I cut my dorsolateral wrist just proximal to the radial styloid process two weeks ago when a heavy mirror broke and fell on it, and it required seven stitches. There was bruising on the entire dorsal surface of my hand and several inches up my ventral forearm, but that's mostly gone now We set out to investigate to incidence of superficial radial nerve damage due to radial styloid K wires. Injury to the sensory branch of the superficial radial nerve was seen in eight (20%) out of the 40 patients. K wiring is a popular technique to help maintain anatomic reduction of distal radial fractures The superficial branch of the radial nerve descends lateral to the radial artery and passes backward under the tendon of the brachioradialis muscle. It then continues distally between the brachioradialis and supinator muscles before descending onto the dorsum of the hand

Reported success rates for decompressing the radial nerve in patients with radial tunnel syndrome vary between 10 and 95%. The combined treatment, releasing both the posterior interosseous nerve an.. Motor function. The radial nerve innervates the muscles located in the posterior upper arm and posterior forearm. In the upper arm, it innervates the three heads of the triceps brachii - which acts to extend the arm at the elbow. The radial nerve also gives rise to branches that supply the brachioradialis and extensor carpi radialis longus (muscles of the posterior forearm) The superficial radial nerve runs under the brachioradialis muscle on the lateral aspect of the radial artery and should be retracted laterally. 3. Deep dissection: proximal third. The supinator muscle covers the lateral aspect of the proximal radius. The posterior interosseous nerve (also known as deep branch of the radial nerve) lies within. The superficial branch of the radial nerve can be damaged due to direct trauma causing soft tissue injuries in the forearm such as stabs or lacerations. The only branch may be involved is the superficial branch of the radial nerve which is purely sensory. The patient will have no motor weakness and there will be sensory loss over the lateral.
Superficial Radial Nerve Biopsy Procedure Your doctor has determined that it is necessary to do a superficial radial nerve biopsy on you. A superficial radial nerve biopsy is a procedure in which the doctor makes a small surgical cut over this nerve (close to your wrist) and takes a specimen of the nerve for further examination 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 shaf The Radial Nerve.
