|Abstract:||Objective: the Classification proposed by Landim for lumbar spine stenosis could be a method of diagnostic standardization once, on the literature, there are no studies that standardize the use of a classification which allows the comparison of results. It is necessary the evaluation of intra and interobservers ' reproducibility for such system as to validate it for this matter. Methods:pre-operative image exam of lumbosacral column of 11 patients diagnosed with symptomatic lumbar stenosis were selected. The criteria for selection were image exams with good quality and diverse etiologies. The age group ranged from 15 to 87 years and included both sexes. The studied samples were followed at the Ambulatory of Spine Column of the Department of Orthopaedics and Traumatology of the Hospital das Clínicas, Universidade de Campinas (Unicamp), city of Campinas, state of São Paulo, Brazil. Twelve spine surgeons classified the 11 sample exams according to Landim 's Classification in two different moments with a time interval of 3 weeks. The intra and interobservers ' statistical analysis used were the Wilcoxon and the Alpha of Cronbach Tests, respectively. Significant results were considered as P<0.05. Results: the analysis of the addition of the first and second classifications from the 11 cases appraised by 12 spine surgeons with a time interval of 3 weeks, resulted in percentual accordance among intra and interobserver of 65% and 83% for global classification; 80% and 91% for "segment"; 86% and 95% for "type"; 85% and 82% for "area", respectively. The intraobserver reproducibility was 79% and interobserver, 88%. Conclusion: the proposed Classification of Landim has an easy applicability and may become a possible mean to standardize information with good levels of reproducibility and confidence intra and interobservers for more consistent future conclusions related to the pathology of lumbar stenosis.|
