Nerve root block in lumbar disc herniation

Abstract

189 patients(151 men and 38 women)with an average age of 45.2, diagnosed with lumbar disc herniation were treated by nerve root block. They presented with an average JOA score of 12.5 points. The level, localization and migration of the disc herniation were determined by MRI. 105 of 189 cases were deemed unsuitable for surgical intervention. 91 of those 105 cases were followed for more than 6 months. The outcome for these 91 patients was “excellent” in 39 cases, “good” in 45 cases and “poor” in 7 cases. In cases of paracentral type herniation without migration and lateral herniation, spinal nerve root block proved to be ineffective in many 62 cases, and surgery was performed in 57 cases. Our study concluded that spinal nerve root block was more effective in addressing central lumbar disc herniation with migration.
