ABSTRACT
Objective:
Determine if patients undergoing PLIF or TLIF surgery achieved improvement in the score of ODI and SF-36 questionnaires one year after surgery.
Methods:
Retrospective, single-center and non-randomized study. Patients submitted to spinal surgery using the PLIF or TLIF technique were included who completed the ODI and SF-36 questionnaires at least at the preoperative visit, and one year after surgery. Patients were divided into two groups, Group 1 (1 surgery level) and Group 2 (> 1 surgery level) and the ODI and SF-36 scores were compared for improvement.
Results:
The mean age was 47 years, with 52% of males (13/25) and mean of 5 days of hospital stay. Patients presented a significant improvement of ODI questionnaire (p<0.001) and in all SF-36 domains except in General Health State (p=0.58). In each group, it was observed that patients submitted to more than one level of surgery had greater blood loss and shorter hospital stay; however, the improvement obtained in ODI and SF-36 compared to the one-level surgery group was similar.
Conclusions:
PLIF and TLIF techniques are effective and lead to improved scores in ODI and SF-36 questionnaires one year after surgery. Patients undergoing two or more levels of instrumentation showed significant and similar improvement in ODI and SF-36. Level of evidence II, Single-Center Retrospective Study.
