Objective:
This study aimed to systematically identify and quantify the acceptable spino-pelvic parameters for Chinese elderly patients with lumbar stenosis syndrome (LSS) following surgical treatment.
Method:
A prospective study of 165 LSS cases from July 2018 to June 2020 evaluated spino-pelvic alignment using PI, LL, PT, and SVA, categorized by SRS-Schwab classification. Quality of life was assessed via the Oswestry disability index (ODI), and parameter thresholds were determined by AICc and ROC analysis.
Results:
No significant change in radiological parameters was observed postsurgery. However, clinical outcomes improved with lower grades of PI-LL and PT. The mean threshold for PI-LL and PT at baseline was 18.8° and 26.1°, respectively. At the endpoint, PI-LL was 17.7°, and PT was 26.1°, indicating optimal ranges for surgery.
Conclusion:
Spino-pelvic alignment significantly correlates with quality of life in elderly LSS patients. The study suggests that PI-LL and PT should be maintained within 17.7° and 26.1°, respectively, for optimal surgical outcomes.
