Cross-Sectional Study Evaluating Nonoperative and Surgical Treatment for Lumbar Degenerative Spondylolisthesis

Abstract

Introduction Nonoperative treatment is the first prerogative for patients with degenerative spondylolisthesis without neurological deficit. In cases where persistent pain or neurological deficit becomes prevalent, surgery becomes an option. In this cross-sectional study, we evaluated clinical and functional results of patients with lumbar degenerative spondylolisthesis treated nonoperatively or surgically. Patients and Methods Patients with degenerative spondylolisthesis treated either nonoperatively or surgically from 2004 to 2014 were selected from databases and a cross-sectional evaluation was applied. Outcome measures included back and leg visual analog scales (VAS), Fischgrund criteria, short form-36 (SF-36) physical function, and the modified oswestry disability index (ODI). Results Of the 85 patients who met the inclusion criteria, we evaluated 43 in total: 20 with nonoperative treatment and 23 with surgical treatment. Baseline characteristics were similar without significant differences. The mean follow-up time was 43 months (range, 10–72 months) for nonsurgically and 36 months (range, 6–80 months) for surgically treated groups. The surgical group displayed better scores in back VAS (8 vs. 4), leg VAS (6 vs. 3), SF-36 physical function (35 vs. 77), and ODI (46 vs. 17). On the basis of the Fischgrund criteria, only 10% of patients reported excellent or good health post nonoperative treatment versus 83% for those treated surgically. Conclusion Symptomatic patients with lumbar degenerative spondylolisthesis treated surgically obtained better clinical and functional scores than patients treated nonoperatively. The limitations of the study do not permit statistical analysis and hence further review is necessary to draw firm conclusions.
