title: [Application of selective nerve root blocks in limited operation of the lumbar spine].
abstract: OBJECTIVE
  To summarize the clinical application result of the selective nerve root blocks in limited operation of the lumbar spine.
  
  
  METHODS
  From January 2008 to October 2012,68 patients with lumbar spinal canal stenosis with multiple levels were underwent the selective nerve root blocks in limited operation of the lumbar spine,including 47 males and 21 females with an average age of 56 years old ranging from 45 to 80. After never roots blocks,64 cases were positive for limited operation of the lumbar spine; the other 4 cases were negative and abort the operation.
  
  
  RESULTS
  The nerve roots block operation smoothly and no complications related to the nerve roots block occurred. There was no neurologic injury complication in this study. Follow-up period ranged from 16 to 45 months postoperatively (means, 32 months). The recovery effect was calculated with Macnab scores, the result was excellent in 44 cases, good in 18 cases, poor in 1.
  
  
  CONCLUSIONS
  Operative treatment for lumbar spinal canal stenosis with multiple levels is focused on the areas causing symptomate neural compression rather than prophylactic decompression at areas of nonsymptomatic disease. Application of selective nerve root blocks can accurately judge the responsible vertebral body and pain source and improve the curative effect of limited operation of the lumbar spine
