S64.2
Injury of radial nerve at wrist and hand level
Clinical Classification Guidelines
Medical Intelligence & Overview
Radial nerve injury at the wrist and hand level is a condition that affects the function of the radial nerve, a major nerve responsible for movement and sensation in parts of the arm and hand. This injury can result from trauma, repetitive movements, or other causes, leading to weakness, numbness, or paralysis of certain muscles and sensation changes in the affected area. Recognizing the symptoms and understanding the causes can help in seeking appropriate medical care and management.
Causes & Symptoms
Clinical Causes: Trauma or fractures near the wrist or forearm Repeated or prolonged pressure on the radial nerve, such as in tight splints or casts Surgical procedures involving the forearm or wrist Lacerations or cuts in the area of the nerve Trauma from falls or accidents causing nerve compression or injury Overuse injuries from repetitive movements, especially in occupations or activities that involve wrist extension Swelling or inflammation from conditions like arthritis or infections
Key Symptoms: Weakness in wrist and finger extension, leading to difficulty lifting the wrist (wrist drop) Numbness or decreased sensation on the back of the hand and forearm Loss of ability to perform certain movements like wrist extension or thumb movements Pain or tingling sensation along the nerve distribution Muscle wasting in the affected areas in long-standing cases Difficulty gripping objects or performing fine motor tasks
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a thorough medical history and physical examination to assess muscle strength, sensation, and nerve function. Healthcare providers may perform specific tests, such as nerve conduction studies and electromyography (EMG), to evaluate nerve damage. Imaging tests like X-rays, MRI, or ultrasound may be used to identify the cause of the injury and its location.
Treatment Protocols: Rest and immobilization to prevent further injury Physical therapy to strengthen muscles and improve movement Medications to reduce pain and inflammation Splinting or orthotic devices to support wrist and hand Surgical intervention in cases of severe nerve damage or entrapment Monitoring and follow-up to assess nerve recovery over time
