Preoperative Factors Predict Postoperative Trajectories of Pain and Disability Following Surgery for Degenerative Lumbar Spinal Stenosis

We investigated for potential predictors of outcome following degenerative lumbar spinal stenosis surgery. In this longitudinal study of 529 patients, approximately one in three patients experienced a poor clinical outcome. Demographic, health, and clinical factors were more predictive of clinical outcome than surgery-related factors.
