Radial Nerve Palsy

What is Radial Nerve Palsy?

Radial nerve palsy is a result of compression of the radial nerve, often caused by fracture of the humerus bone. This results in pain, weakness, or loss of function in a person's wrist, hand, and fingers.


Who gets Radial Nerve Palsy?

Anyone can get radial nerve palsy, especially if the radial nerve is injured.


How is Radial Nerve Palsy diagnosed?

After taking the patient's history, a physician may perform an EMG and a nerve conduction study. X-rays or an MRI may also be used to detect injury to the humerus.


How is Radial Nerve Palsy treated?

Treatment usually depends on the reason for the radial nerve palsy. If the palsy is caused by swelling, anti-inflammatory medication can be used to relieve pressure on the nerve. If the humerus has been injured, splinting can be used to help keep the limb stable and allow the body to heal. Depending on the level of injury, surgery may also be required.
