Radial Nerve: How to Identify and Treat Injuries
The radial nerve is one of the main nerves of the arm and hand, responsible for sensation and movement in various structures. An injury to this nerve can cause pain, weakness, and even paralysis in severe cases. When the radial nerve is compromised, patients may struggle with simple daily tasks such as holding objects, writing, or even moving the wrist. This issue can arise due to fractures, prolonged compression, or neuromuscular diseases that affect nerve conduction. In this article, we will explain what the radial nerve is, how to identify related problems, and the available treatment options to improve recovery and quality of life.
What is the Radial Nerve?
The radial nerve is one of the three main nerves in the arm, running from the armpit to the hand. It controls the extensor muscles of the wrist, fingers, and forearm, as well as providing sensation to the back of the arm and hand. When a radial nerve injury occurs, there may be partial or total loss of hand and finger mobility, making basic functions difficult. The primary cause of these injuries is direct trauma, such as falls or accidents that result in humerus fractures. Additionally, prolonged compression, such as sleeping in improper positions, can temporarily impair nerve function. Early diagnosis can minimize damage and initiate effective treatment to restore radial nerve function.
Radial Nerve in the Arm: Symptoms and Causes
Radial nerve injuries can result from various factors, including bone fractures, prolonged compression, direct trauma, or neuromuscular diseases. The main symptoms include:
- Numbness and tingling in the forearm and hand.
- Weakness in wrist and finger extension.
- Difficulty lifting the hand (wrist drop).
- Persistent pain in the arm and wrist.
If you experience any of these symptoms, it is essential to consult a specialist to assess the severity of the problem and recommend appropriate treatment. Radial nerve injuries in the arm can be temporary or permanent, depending on the severity. In many cases, recovery is slow and can take months, requiring continuous physical therapy and the use of orthopedic splints to stabilize the joint and facilitate regeneration. Early detection of the problem can prevent severe complications and accelerate the recovery of mobility and sensation in the affected limb.
Radial Nerve Paralysis: Diagnosis and Treatment
Radial nerve paralysis occurs when a severe injury prevents normal movement of the muscles innervated by the nerve. Diagnosis is conducted through clinical examinations and, in some cases, imaging tests such as electromyography, which evaluates nerve conduction. Paralysis can be partial or complete, depending on the extent of the injury.
Treatment options include:
- Wrist and thumb immobilization: The use of orthoses and immobilizing splints, such as the Thumb Immobilizing Splint, helps stabilize the joint and reduce pain.

- Physical therapy: Specific exercises can aid in regaining strength and mobility, promoting nerve regeneration and strengthening surrounding muscles.
- Medications: Anti-inflammatory drugs and pain relievers may be prescribed to alleviate pain and reduce inflammation that may be compressing the nerve.
- Surgery: In severe cases, surgical intervention may be necessary to restore nerve function. Surgery may involve nerve grafts or decompression procedures to facilitate radial nerve recovery.
Sensory Radial Nerve: Function and Recovery
The radial nerve plays an important sensory role, responsible for the perception of sensations on the back of the arm, forearm, and hand. When this nerve is injured, there may be partial or total loss of sensation, along with neuropathic pain. In cases of sensory radial nerve injury, numbness and tingling can persist for weeks or months, requiring constant medical monitoring. Rehabilitation may include nerve stimulation therapies and the use of splints to prevent positions that worsen the condition. Proper treatment allows patients to recover sensory nerve function over time, preventing complications such as muscle atrophy and loss of motor coordination.
How to Stimulate the Radial Nerve for Faster Recovery?
Radial nerve stimulation can be achieved through physical therapy and electrostimulation, techniques that help restore neuromuscular function. Additionally, the use of support devices, such as the Manumed Wrist Immobilizing Splint with Thumb, can aid in recovery by preventing movements that aggravate the injury.

Rehabilitation techniques include passive and active mobilization exercises, stretching, and manual therapies that help restore blood circulation and flexibility in the affected limb. The sooner a patient begins rehabilitation, the higher the chances of achieving a full and effective recovery.
Radial Nerve Injury: How to Prevent and Treat It
To prevent radial nerve injuries, some measures can be taken:
- Avoid prolonged pressure on the arm during sleep or repetitive activities.
- Perform stretching and strengthening exercises for the arm and wrist muscles.
- Use orthopedic supports when necessary, such as the Long Elastic Wrist With Palm an Thumb Splint

- Seek medical assistance at the first sign of prolonged weakness or numbness. The sooner an injury is treated, the better the prognosis and recovery for the patient.
Conclusion
The radial nerve plays a crucial role in the mobility and sensitivity of the arm and hand. An injury to this nerve can cause significant limitations, but with early diagnosis and appropriate treatment, functionality can be restored. The use of splints and orthoses can be a great ally in recovery, allowing muscles to rest while regeneration occurs. Additionally, physical therapy rehabilitation and specialized medical follow-up are essential to ensure effective recovery and prevent future injuries.
