Objective: To evaluate functional results in patients submitted to lumbar arthrodesis for the treatment of degenerative disc disease. Methods: This is a retrospective study that considered patients submitted to surgery due to degenerative disc disease, with a minimum of 12 months of postoperative follow-up. The Oswestry Disability Index (ODI) and Scoliosis Research Society-22 (SRS-22) questionnaires, including total value and domains, were considered indicators of functional outcome and quality of life. Results: Sixty-one patients (mean age 60.4 years) met the inclusion criteria and had ODI and SRS-22 data recorded. Nineteen were male and 42 female. The mean of postoperative follow-up was 29 months (12-67 months). There was no statistically significant difference in any score between sexes. The mean values obtained by the questionnaires were ODI 43.4%; SRS-22 Total 2.7; Function/Activity 2.6; Pain 2.8; Appearance 2.6; Mental Health 3.0; Satisfaction 3.4. Conclusion: The values of the surgical outcome indicators were consistent with important functional disability, although the satisfaction indicator with the treatment showed satisfied patients.
