Overview

Observational cohort study identifies factors influencing surgery outcomes for spinal disorder.

Key Points

  • The aim is to identify predictive factors impacting surgical outcomes in degenerative lumbar spondylolisthesis patients.
  • Observational cohort study involving 52 patients aged 45-75 with single-level degenerative spondylolisthesis.
  • Patients underwent lumbar interbody fusion, with outcomes measured using VAS and ODI.
  • Logistic regression and multivariate analysis were performed to assess predictors of unfavorable outcomes.
  • Significant predictors of unfavorable outcomes included facet angle (P = 0.039), lateral listhesis (P = 0.021), and disc height (P = 0.032).
  • Inadequate post-operative disc height restoration resulted in slower recovery.
  • Favorable outcomes showed significant improvements in VAS scores from 7.0 to 2.5 and ODI scores from 28 to 8 at 6 months.
