What is Radial Nerve Palsy?

Definition and Overview

Radial nerve palsy is a unique condition affecting the biggest nerve in your upper limb. It starts from the shoulder, goes through the arm to the wrist’s back. If this nerve is hurt, daily tasks can get much harder.

Role of the Radial Nerve

The radial nerve is key for moving and feeling in your arm and hand. Injuries can lead to weakness and numbness. This makes it hard to move your elbow, wrist, and fingers.


The radial nerve is vital for arm muscles. It can be hurt by accidents, doing the same motions over and over, or health issues. Knowing about radial nerve palsy helps in how to treat and cope with this problem.

Symptoms of Radial Nerve Palsy

When the radial nerve is hurt or not working well, it causes several symptoms. These can make it hard to do your daily tasks. It’s important to know these signs to deal with radial nerve palsy properly.

Numbness and Tingling

You might feel numbness and tingling if you have radial nerve palsy. This happens in the back of your hand and your thumb, index, and middle fingers. The radial nerve helps these areas feel things.

Weakness and Loss of Movement

With this condition, your fingers may get weak and lack coordination. This makes it hard to do things that need careful hand movements. Also, straightening your arm at the elbow can be tough, which is because of the radial nerve.

Wrist Drop

“Wrist drop” is a key sign of radial nerve palsy. Your wrist hangs loose and you can’t lift it. The nerve controls the muscle that extends the wrist and fingers, causing this function to be lost.

radial nerve palsy symptoms

The exact symptoms you have can change based on where and how badly the nerve is injured. If you think you might have radial nerve palsy, see a doctor. Early treatment and care can make a big difference in how well you recover.

Causes of Radial Nerve Palsy

The reasons for radial nerve palsy vary from person to person. They all have different effects and ways they happen. Knowing these causes is key to how we deal with, treat, and stop this issue.

Traumatic Injuries

Breaking or dislocating bones can often cause radial nerve palsy. A break in the humerus bone, especially near the elbow’s end in a spiral shape, is a big risk. It can lead to palsy in about 15% to 25% of cases. This happens because strong impacts can hurt or press against the nerve, causing the usual symptoms.

Compression or Entrapment

If the radial nerve is pressed or trapped, it can also cause issues. Using crutches not the right way, wearing tight casts, or having certain health problems can press on the nerve. This stops the nerve from working right, causing numbness, trouble moving, and coordination issues in parts of the body.

Underlying Medical Conditions

Health conditions like diabetes, alcohol misuse, and other nerve issues can also be a factor in radial nerve palsy. These issues can hurt the nerves, increasing the risk of palsy. This is especially true for people already dealing with nerve problems or other nervous system conditions.

Diagnosing Radial Nerve Palsy

Getting a right diagnosis is key in treating radial nerve palsy and boosting your recovery. Your doctor will use a mix of exams, tests, and studies to check how bad your nerve issue is.

Physical Examination

To start, your doctor will give you a careful physical exam. They’ll look at symptoms like lack of strength, feeling less, and trouble moving your arm, wrist, or hand. This helps find exactly where the nerve is damaged, and rules out other possible reasons for your issues.

Imaging Tests

Your doctor might also order some tests like X-rays, ultrasound, or MRI scans. These can show if there are any issues like broken bones, tumors, or other things pressing on your nerve. Finding these problems is an important step in diagnosing your condition.

Nerve Conduction Studies

Tests like EMG and NCS play a big role in confirming and gauging how bad the radial nerve palsy is. They check the flow of electricity in the nerve, helping to see if the issue is in the nerve itself or in the nearby muscles. This test is also useful in watching how well your nerve is healing.

With careful exams and high-tech tests, your healthcare team can spot radial nerve palsy and set up a plan that fits you. This detailed approach is needed to treat the issue well and raise your chances of getting better.
