Multivariate Analysis and Risk Factors Were Used to Predict the Short-term Postoperative Pain of Degenerative Lumbar Spine

Inclusion Criteria: 1. confirmed diagnosis of lumbar degenerative disease (spinal stenosis, disc herniation with lumbar instability, and lumbar spondylolisthesis), with no significant symptomatic relief after conservative treatment for more than 3 months, and in need of surgical intervention; 2. lumbar spinal fusion surgical treatment with PLIF; 3. grouping based on the presence or absence of a lumbar or limb pain with VAS ≥3 at the 3th month postoperative follow-up; 4. observational indicators including individual factors, surgical factors, spine-pelvis sagittal balance parameters, and paravertebral muscle parameters. Exclusion Criteria: (1) those with a history of lumbar spine trauma, inflammation, tumor, or surgery; (2) those with congenital or acquired severe lumbar vertebral deformity; (3) those with severe neurological dysfunction; (4) those with incomplete baseline and follow-up data.
