Abstract
|
|
|
|
The main cause of radiating pain frequently remains obscure, particularly in those patients with multiple level involvement, recurrent sciatica following surgery on the back or the undetermined etiology of the sciatica by standard clinical and radiologic evaluation. In these cases the selective nerve root block test is a useful diagnostic method to indicate whether the pain is neural in origin and/or whether nerve root is pain producing in these patients with equivocal clinical and imaging studies. The authors performed 169 selective nerve root blocks in 94 patients. The follow up period was more than 6 months. In cases, more than 50% improvement of leg pain was 105(62%)cases and one grade or more improvement of neurologic claudication was 108(64%)cases, and the period of improvement was only few days except 4 patients. But the spinal nerve root block was one of the valuable procedure for selection of treatment method.
