[Posterior spinal rami in localization of low back pain].
Objective findings even after standard evaluations could hardly be obtained in some low back pain (LBP). Neurolocalization of LBP is dependent on the relationship between the complaint site of pain and the distribution of the posterior branch of the spinal nerves to search for the source and to localize the level of injury. The primary sites of LBP we suggested are higher than the complaint site. In 1263 cases of LBP, the results of contrast test with procaine injection at both sites have shown that nearly all the complaint sites are secondary. According to the theory as mentioned, satisfactory effects of 1108(87.73%) of 1263 treated by freezing the posterior spinal rami at the primary site have been obtained.
