Spinal and radicular pain disorders.

Although most acute conditions of the spine are benign and self-limited, the economic costs and disability resulting from these disorders have reached epidemic proportions in industrialized society. Recent scientific research to determine the causes of common spinal disorders, long attributed to structural abnormalities, have now implicated complex biochemical and neurophysiologic processes which may offer insights for future therapy interventions. This article reviews the functional and pathologic anatomy and correlates with current diagnostic and nonoperative management strategies for common mechanical spinal and radicular pain syndromes.
