Interventions

Procedure/Surgery : To determine symptom related lesions, RFSS was performed for suspected nerve roots on MRI. (Fig. 1) RFSS resembled transforaminal steroid injection6. Detailed processes are as foll

lildocain for pain control.

Inclusion criteria

Inclusion criteria: From 2010 to 2012, consecutive patients who received RFSS and underwent spine surgery in single institute were enrolled for this study. . MRI for patients who presented low back pain and leg radiating pain revealed multiple lumbar spinal stenosis and/or lumbar herniated disc with spondylosis. In specific cases, minimal invasive approach was required because of their medical illness such as rheumatoid arthritis, bone marrow transplanted state, or aplastic anemia. Effect of RFSS on reducing surgical range of multiple lumbar stenosis was measured. Difference in surgical range was compared between groups depending on whether RFSS was used. For this comparison, historic control (HC) group of patients who had received spinal surgery for multiple lumbar stenosis were selected. The HC group was sex-age-diagnosis matched group of RFSS group (R group). Of 1,141 patients who underwent spinal surgery from 2008 to 2014, those whose sex, age, and preoperative diagnosis matched with R group patients were enrolled for the HC group. There were three subgroups according to their numbers. For comparison, HC subgroup was set at 1x, 2x, 3x than the number of patients in the R group. Medical records and MRI of the historic group were reviewed. The number of roots that might be related to the patient’s original symptom was checked on preoperative MRI. Surgically decompressed segment of each patient was reviewed and the difference between preoperative and operative numbers was calculated.
