Complications of Spinal Injection Therapy and Discography

Spinal injection procedures are commonly performed for therapeutic and diagnostic purposes. Diagnosis of a spinal problem begins with the history and physical examination. Anatomical studies such as magnetic resonance imaging (MRI) and computed tomography (CT) scans should be viewed in the context of the clinical scenario. Abnormal findings may be seen in patients without any clinical complaints (1,2). Electrodiagnostic studies are a physiological tool used to identify lower motor neuron lesions. Sensitivity and specificity of EMG=NCV is not perfect (3).
