S54.20

Clinical Causes: Traumatic injuries such as fractures or deep cuts to the forearm Blunt force impacts from accidents or falls Repeated pressure on the nerve, like prolonged use of crutches or splints Surgical procedures near the nerve, including orthopedic or vascular surgeries Penetrating injuries from stab wounds or projectiles Nerve compression from swelling, tumors, or other masses in the forearm

Key Symptoms: Weakness or paralysis of wrist and finger extension Numbness or tingling sensations along the back of the hand and forearm Difficulty performing movements such as wrist drop or finger extension Loss of sensation in specific areas supplied by the radial nerve Decreased grip strength or inability to lift the hand Pain radiating along the nerve pathway in some cases

Diagnosis Path: Diagnosis involves a thorough clinical examination assessing motor and sensory functions. Medical professionals may use nerve conduction studies and electromyography (EMG) to evaluate nerve damage. Imaging tests such as MRI or ultrasound can help identify underlying causes like swelling or tumors. A detailed history to identify recent trauma or medical procedures is also essential.

Treatment Protocols: Rest and immobilization to prevent further injury Physical therapy to regain strength and mobility Pain management through medications or nerve blocks Surgical intervention for nerve repair or decompression in severe cases Splinting or bracing to support affected limbs and prevent deformities Monitoring progress with regular follow-up assessments
