BACKGROUND: The pathophysiology of pain in symptomatic thoracic disc herniation (TDH) patients remains poorly understood. Mere mechanical compression of the spinal cord and/or the exiting nerve root by a prolapsed disc cannot explain the pathogenesis of pain in all cases. Previous studies report a direct correlation between the levels of proinflammatory cytokines in disc biopsies and the severity of leg pain in patients with lumbar disc herniations. A similar correlation in patients with TDHs has not been investigated...
