Description

46 patients (23 men and 23 women) with an average age of 70.2 were diagnosed with lumbar canal stenosis and were treated by nerve root block. They presented with an average JOA score of 15.3 points. We evaluated JOA score, the findings of the myelogram and the diameter of the lateral recess. The surgery was performed in 15 cases. 31 of 46 cases were deemed unsuitable for surgical intervention. All those cases were followed up for more than 6 months. The outcome for these 31 patients was “excellent” in 12 cases, “good” in 10 cases and “poor” in 9 cases. Our study concluded that spinal nerve root block was more effective in addressing radicular symptoms without severe lateral stenosis.
