简介
Introduction
Anterior Lumbar Interbody Fusion (ALIF) and Posterior Spinal Fusion (PSF) play pivotal roles in restoring lumbar lordosis in spinal surgery. Debates persist between combined single-position surgery and traditional prone-position PSF for optimizing segmental lumbar lordosis.
Research Question
The study investigates the impact of performing ALIF in the supine position followed by PSF in the prone position on segmental lumbar lordosis.
Material and Methods
A cohort of 59 patients underwent ALIF and PSF at a single institution. Preoperative, post-ALIF supine, and post-PSF prone Cobb angles were assessed using x-ray imaging. Statistical analyses, including one-way repeated measures ANOVA and Post-hoc analyses with Bonferroni adjustment, were employed for mean comparisons within subjects.
Results
The mean Cobb angle for the entire cohort showed significant variations over different time points (p).
