ObjectiveTo evaluate clinical result of the micro-decompression procedure for lumbar spinal stenosis.MethodsFrom September 2001 to May 2006,87 patients (male 60, female 27) with lumbar spinal stenosis underwent micro-decompression. The age of patients were from 43 to 80 years with an average of 51 years. Among them,2 cases with spinal stenosis occured in L(3,4), 47 in L(4,5), 38 in L5S1.ResultsAll patients were followed up for 18-48 months with an average of 26 months. The results were excellent in 52 cases, good in 28, poor in 7, according to Macnab of back leg pain standard. The rate of excellent and good was 92%.ConclusionOperative treatment for lumbar spinal stenosis is focused at the areas causing symptomatic neural root compression rather than prophylactic decompression at areas of nonsymptomatic disease. The micro-decompression procedures are more likely to be well tolerated by older patients.
