Decision-making process in patients with lumbar spinal canal stenosis
2014
Abstract The aim of this study was to develop a strategy to determine a sound methodology for decision-making in lumbar spinal canal stenosis (LSCS). This was a retrospective study of patients with LSCS to determine the rationale for those who underwent surgery and those who received conservative treatment. All case records were assessed to extract information on the morphology grade and dural sac cross-sectional surface area (DSCA) on MRI. Patients' functionality and satisfaction were examined as outcome measures in order to understand factors that were associated with benefit from either treatment strategy. In all 357 patients, case records were reviewed. The mean age of patients was 57.5 (SD=10.9) years. Of these, 176 patients underwent surgery. Post-treatment satisfaction was found in a large portion of the surgical group (93.2%) whereas this was 84.5% for those who received conservative treatment. Most patients (86.4%) who underwent surgery were identified as having grade C and grade D stenosis, while those who received conservative treatment were identified as having grade A and grade B stenosis (P
