G56.3
Lesion of radial nerve
Clinical Classification Guidelines
Medical Intelligence & Overview
A lesion of the radial nerve refers to damage or injury to the radial nerve, a vital nerve in the arm that controls movement and sensation. Located along the back of the upper arm and forearm, this nerve plays a key role in extending the wrist and fingers, as well as providing sensory input from parts of the hand. Damage to this nerve can lead to weakness, numbness, or paralysis in specific areas of the arm and hand, affecting daily activities and quality of life.
Causes & Symptoms
Clinical Causes: Trauma or fractures to the humerus (upper arm bone) Direct injury from cuts, burns, or surgical procedures near the nerve Compression of the nerve due to prolonged pressure or swelling Repeated arm movements causing nerve entrapment Tumors or growths pressing on the nerve Certain medical conditions such as multiple sclerosis or peripheral neuropathy
Key Symptoms: Weakness in wrist and finger extension, resulting in difficulty straightening the wrist and fingers (wrist drop) Numbness or tingling sensation on the back of the hand and forearm Reduced grip strength Decreased ability to perform tasks requiring wrist or finger movements Pain or discomfort along the nerve pathway Loss of sensation on the back of the hand, thumb, and part of the back of the forearm
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a thorough clinical examination where a healthcare provider assesses muscle strength, reflexes, and sensory responses. Electromyography (EMG) and nerve conduction studies may be performed to evaluate nerve function and pinpoint the location and severity of the lesion. Imaging tests such as X-rays, MRI, or ultrasound can help identify any structural causes like fractures or tumors affecting the nerve.
Treatment Protocols: Treatment options are tailored to the cause and extent of the nerve lesion. They often include:
