title: [Clinical course of decompressive surgery for the treatment of lumbar stenosis].
abstract: Several authors and publications have focused on comparing the clinical course of nerve root decompressive surgery, with or without fusion, to treat degenerative lumbar stenosis. However, there are not many reports analyzing the clinical course after decompressive surgery of a single nerve root (the most symptomatic one) comparing it with decompression of all the roots in a segment. This study intends to compare the clinical course after decompressing the most symptomatic lumbar nerve root with the release of multiple lumbar nerve roots to relieve neuropathic pain resulting from degenerative lumbar stenosis.
  
  
  
  A prospective, observational, descriptive longitudinal study was performed. A total of 38 patients were divided into two groups that included each 19 cases. Patients underwent recalibration of either a single nerve root or multiple nerve roots of a segment. Percentages were calculated as well as the Student t test and the Pearson correlation.
  
  
  
  In group A, a decrease of 46.63 points was seen in the Oswestry scale, representing a 66.73% improvement in pain. In group B, in turn, a mean decrease of 34.54 points was seen in the Oswestry scale, equivalent to a 47.23% improvement in pain, with a Student t in which p = 0.11 and a Pearson correlation coefficient of 0.08.
  
  
  
  No statistically significant differences were found between both study groups.
