Foraminal Imaging and Symptoms in Single-Level Degenerative Lumbar Stenosis
Correlation Analysis Between Foraminal Imaging Morphology and Clinical Symptoms in Patients With Single-Level Degenerative Lumbar Spinal Stenosis
This retrospective observational study investigated the correlation between foraminal imaging morphology (evaluated by MRI 4-level score and CT Haleem-Botchu classification) and the severity of clinical symptoms in patients with single-level degenerative lumbar spinal stenosis. A total of 120 adult patients treated between January 2024 and December 2025 were included. Patients were categorized into mild, moderate, and severe groups based on their Visual Analog Scale (VAS) scores. The study analyzed the correlation of imaging grades with clinical functional scores (ODI and VAS) and identified independent imaging factors associated with symptom severity. No new treatments or extra hospital visits were involved.

상세 설명
To ensure data validity, two independent radiologists, who were blinded to the patients' clinical information and grouping, evaluated the imaging grades at the responsible segment on the symptomatic side. Inter-observer reliability was assessed using the weighted Kappa coefficient.

연구 인구
This retrospective cohort study initially screened 289 consecutive patients diagnosed with single-level degenerative lumbar spinal stenosis between January 2024 and December 2025. After applying strict inclusion and exclusion criteria, a final cohort of 151 eligible patients was established. From this cohort, a stratified sampling method was applied to select 120 patients (40 patients per group) to ensure balanced statistical power, categorizing them into mild (VAS 1-3), moderate (VAS 4-7), and severe (VAS 8-10) symptom groups based on their baseline Visual Analog Scale (VAS) scores. Clinical and imaging data were extracted for correlation and regression analysis.

Correlation Between Imaging Grading and VAS Pain Scores
기간: Baseline (at index imaging; single time-point cross-sectional assessment)
|
The correlation between the severity of foraminal stenosis (assessed by MRI 4-level score and CT Haleem-Botchu classification) and Visual Analog Scale (VAS) pain scores in patients with single-level degenerative lumbar spinal stenosis. The association was analyzed using the Spearman rank correlation coefficient. |
