What is the superficial radial nerve?

The superficial radial nerve is a pure sensory nerve, a branch of the radial nerve that arises from the bifurcation of the radial nerve in the proximal forearm as it leaves the arcade of Frohse and travels deep to the brachioradialis in the forearm.

What does superficial branch of radial nerve innervate?

The superficial branch of the radial nerve provides sensory innervation to much of the back of the hand, including the web of skin between the thumb and index finger.

What is a superficial radial nerve lesion?

[1][2] It is also commonly known as Wartenburg syndrome and superficial radial nerve palsy. The superficial radial nerve is purely sensory and does not have any motor component. The condition presents with symptoms such as pain and burning located on the dorsal and radial side of the hand.

What is the radial nerve responsible for?

The radial nerve travels down the arm and supplies movement to the triceps muscle at the back of the upper arm. It also provides extension to the wrist, and helps in movement and sensation of the wrist and hand.

Where is the superficial radial nerve located?

forearm

As a branch of the radial nerve the superficial radial nerve receives fibers from all roots of the brachial plexus (C5-T1). It branches under the proximal tendon of the brachioradialis muscle in the upper to middle third of the forearm.

Where is the radial nerve most superficial?

In the hand, the superficial branch of the radial nerve most commonly supplied branches to the thumb, the index finger, and the dorsoradial aspect of the long finger.

Where is the radial nerve most likely to be damaged?

A radial nerve injury refers to damage to the nerve in the upper arm. This nerve controls the triceps muscle. It also helps extend the wrist and fingers and provides sensation in part of the hand. The radial nerve is close to the bone in the upper arm, so it is vulnerable to injury, especially if the arm breaks.

What are the symptoms of radial nerve damage?

Symptoms. Symptoms of radial nerve injury may include pain, numbness, and/or paresthesia, especially in the middle finger, index finger, thumb, back of the hand, and/or arm. Wrist drop and finger drop may also be present.

How do you treat radial nerve damage?

To treat a radial nerve injury, your doctor may suggest a splint or over-the-counter pain medicine. In some cases, you may need physical therapy or a nerve block, an injection to lessen the pain. Surgery may be necessary if the nerve is entrapped, torn, or compressed by a growth.

Can radial nerve damage be permanent?

Partial or complete loss of wrist or hand movement: If the radial nerve doesn’t heal completely, weakness may be permanent.

How do you test for radial nerve damage?

An EMG measures the electrical activity in your muscle. A nerve conduction test measures the speed at which impulses travel along your nerves. These tests can help determine if you are experiencing a problem in your nerve or in your muscle. They may also show whether the radial nerve is damaged.

What would happen if the radial nerve was damaged?

This nerve controls movement and sensation in the arm and hand and extension of the elbow, wrist and fingers. Radial nerve palsy is a condition that affects the radial nerve and if damage to this nerve occurs, weakness, numbness and an inability to control the muscles served by this nerve may result.

Can radial nerve damage be repaired?

Many radial nerve injuries heal on their own. Others require surgical treatment. Surgery type will depend on the injury. At the Peripheral Nerve Center, we have expertise in all types of peripheral nerve surgery.

Can radial nerve damage heal?

How long does radial nerve damage take to heal?

Most people with a radial nerve injury will recover within three months of starting treatment if the nerve is not torn or lacerated. But some cases ultimately require surgery. If your radial nerve is entrapped, surgery can relieve pressure on the nerve.

How do you fix radial nerve damage?

If your radial nerve is entrapped, surgery can relieve pressure on the nerve. If there is a mass, such as a benign tumor, on your radial nerve, you may need surgery to remove it. The goal of surgery is to repair any damage to the nerve.

How long does it take for radial nerve to heal?

Patients typically recover 4 months after starting treatment as long as the nerve is not lacerated or torn. The prognosis for patients with acute compressive radial nerve injuries is good.

What does radial nerve damage feel like?

Is radial nerve damage permanent?

In some cases, complications may occur, including: Partial or complete loss of feeling in the hand: If the radial nerve doesn’t heal completely, numbness may be permanent. Partial or complete loss of wrist or hand movement: If the radial nerve doesn’t heal completely, weakness may be permanent.
