The Radial Nerve: What Happens When its Injured or Strained?

Radial nerve

The radial nerve governs the movement of the triceps muscle, which is positioned in the rear of the upper arm and goes down the underside of your arm. The radial nerve is in charge of wrist and finger extension. It also regulates the sensation in a portion of the hand.

What does the radial nerve innervate?

Radial neuropathy, also known as radial nerve palsy, is caused by an injury to the radial nerve. Physical trauma, illness, or even exposure to poisons can cause radial nerve injury. Numbness, tingling, and scorching pain are common side effects. It’s also possible that it’ll be painless. Your wrist, hand, or fingers may become weak or difficult to move as a result of the illness.

In many circumstances, if the underlying reason is addressed, including maintaining optimum weight, the condition will improve.

Radial nerve damage causes

The radial nerve can be injured for a variety of reasons. These are some of them:

* Breaking your humerus (an upper arm bone) * Sleeping with your upper arm in an awkward position * Pressure from hanging your arm over the back of a chair * incorrectly using crutches * Falling on or being struck in the arm * Long-term restriction of your wrist

Breaking your arm, overusing your arm, and sports and work accidents are the most prevalent causes of radial nerve injury. The radial nerve may be completely lacerated depending on the severity of the injury. When a nerve is cut, something happens. It can produce symptoms that are similar to those associated with relatively modest injuries. A laceration of the nerve typically necessitates surgical intervention.

When certain behaviors are repeated frequently enough, they might cause radial nerve injury. Swinging a hammer, for example, involves both grabbing and swinging movements, which can cause nerve injury over time. These actions can cause the radial nerve to become trapped, constricted, or stretched as it passes back and forth over the bones of your wrist and forearm.

Long-term nerve damage can also result from lead poisoning. The lead toxin can affect the nervous system as a whole over time.

One nerve might be damaged by some health issues that affect the entire body. Inflammation, fluid retention, and other symptoms caused by kidney disease and diabetes can lead to nerve compression. The radial nerve, as well as other nerves in your body, may be affected.
