Overview

Retrospective cohort study shows clinical deterioration in 19.3% of adults with lumbar spinal stenosis, indicating key risk factors and protective measures.

Key Points

  • Clinical deterioration affected 19.3% of patients over a mean follow-up of 121 months, with major issues including reduced walking tolerance.
  • Among 202 adult patients with symptomatic lumbar spinal stenosis, 92.3% of those deteriorating reported neurogenic claudication.
  • In a retrospective cohort analysis, risk factors included lumbar developmental stenosis, while an increased dural sac area was protective.
  • Findings support conservative management for patients with tolerable symptoms and low functional expectations, especially without significant risk factors.
