In the "flexion-adduction" sign, the arm is maintained in a posture of flexion at the elbow and adduction at the shoulder. Abduction and lateral rotation of the arm, with the elbow in extension, may result in radicular pain. These signs may be useful in the evaluation of patients with cervical root or brachial plexus lesions.
