Quality of Life Assessment in Patients Undergoing Surgical Treatment for Adolescent Idiopathic Scoliosis, According to the Last Vertebra Instrumented

Abstract

Objective: Evaluate the influence of the last instrumented vertebra on the quality of life of patients undergoing surgical treatment for adolescent idiopathic scoliosis. Methods: This is a retrospective and cross-sectional study, with level 4 of evidence. For this evaluation, the SRS-22r questionnaire was applied. The variables sex, age at the date of surgery, number of instrumented vertebrae and last instrumented vertebrae were correlated with the domains of the SRS-22r questionnaire. Results: 39 patients were evaluated, 33 (84.6%) of whom were female, with a mean age of 14.5 years at the date of surgery. All patients were introduced to arthrodesis posteriorly and instrumented with pedicle screws. The last instrumented vertebrae were D12, L1, L3 and L4. The average number of instrumented vertebrae was 11.9. There was no statistical significance in the correlation between the variables gender and the last instrumented vertebra with quality of life. The correlation between the variable number of instrumented vertebrae and the function / activity domain, as well as the correlation between the variable age at the date of surgery and the satisfaction with the treatment domain, presented statistical significance. Conclusion: The last instrumented level does not seem to interfere with quality of life, although patients with less instrumented levels had better scores in the function / activity domain.
