Abstract
Clinical analysis of low back pain due to degenerative spine disease was carried out using lumbosacral nerve root block at a single level and lumbar sympathetic nerve block. The clinical feature of low back pain relieved by nerve root block was unilateral pain restricted in the area cranial to the medial iliac crest and frequently accompanied with sciatica due to lumbosacral nerve root impairment. Nerve root block can assess to determine whether it is low back pain due to segmental lesion of the spinal column. On the other hand, the clinical feature of low back pain relieved by sympathetic nerve block was pain in paravertebral area on unilateral or bilateral side, but it was nonspecific. Sympathetic nerve block may have the therapeutic effects for pain due to nonsegmental lesion of the spinal column considering anatomic distribution of afferent nerve in the sympathetic trunk.
