Radicular arm pain.

Cervical radiculopathy is a neurological condition caused by dysfunction or compression of a cervical nerve root. Patients often report unilateral neck pain with radiation to the ipsilateral arm, often with sensory changes in a dermatomal distribution. Weakness and reflex changes are also commonly found and can be very troubling for patients. Careful history and examination is important to identify any more concerning features such as progressive symptoms and features of myelopathy, which could prompt surgical management. Although the majority of patients will see an improvement in their symptoms over time with conservative management, surgery is indicated in patients with debilitating pain, progressive neurology, significant weakness, instability or myelopathy. Advancements in surgical techniques offer a range of potential operations that should be considered carefully for each patient. This article outlines the clinical approach to presentation, pathophysiology, diagnosis and management.
