OBJECTIVE: The goal of this study was to evaluate the efficacy of interspinous spacers in degenerative lumbar disease and the evolution of patient’s depression status and somatization preexisting symptoms. METHODS: 20 patients with degenerative lumbar spinal stenosis were evaluated. Considering the different inclusion criteria, patients agreed to participate in the study by signing the written consent form. For clinical and psychosomatic assessment we used Euroqol Score (EQ-5D) for lumbar spine and lower limbs, Visual Analogue Scale (VAS); Oswestry Disability Index version 2.0 and Modified Somatic Perception Questionnaire (MSPQ); and Zung Self-Rating Depression Scale (ZDS). Statistical analysis was performed using Friedman and Wilcoxon tests, with significance level of 0.05. RESULTS: There was an improvement in EQ-5D (p<0.001), VAS for lumbar spine and lower limbs (p<0.001), ODI (p<0.001), without significant changes in MSPQ (p=0.197). CONCLUSION: In patients with degenerative lumbar disease (Benzel grade 2, 3 and Pfirmann grade 3, 4) and stable in psychosomatic terms, the use of interspinous spacers proved effective clinical progression and improved the rate of depression related to the pre-existing pathology.
