Sympathetic nerve innervation in cervical posterior longitudinal ligament as a potential causative factor in cervical spondylosis with sympathetic symptoms and preliminary evidence

According to the experimental result and clinical practice, we hypothesized that sympathetic nerve fibers distributed in PLL may represent a pathologic basis of stimulation induced by cervical vertebral degenerative changes and thus are susceptible to being a potential causative factor in cervical spondylosis with sympathetic symptoms.
