Abstract
Background: Lumbar spondylodiscitis, particularly at the L4/5 and L5/S1 segments, poses significant clinical challenges due to their impact on spinal stability and function. This study aims to evaluate the efficacy of robot-assisted uniportal spinal endoscopy in treating this disease.
Methods: This retrospective cohort study include 96 consecutive patients with lumbar spondylodiscitis treated from January 2022 to December 2022. Patients were classified into a robot-assisted group (n = 47) and a traditional surgery group (n = 49) according to the surgical approach received. The primary outcomes included operative time and length of hospital stay. Secondary outcomes included operative time, intraoperative blood loss, fluoroscopy time, complications, and family satisfaction. Longitudinal changes in C-reactive protein (CRP), interleukin-6 (IL-6), procalcitonin (PCT), white blood cell count (WBC), erythrocyte sedimentation rate (ESR)), and visual analog scale (VAS) scores were analyzed using repeated-measures analysis of variance (ANOVA).
Results: Compared with the traditional surgery group, the robot-assisted group showed reduced operative time, shorter hospital stay, decreased fluoroscopy time, lower intraoperative blood loss, and higher overall family satisfaction rate (all P < 0.05). The total complication rates were comparable between the two groups (P = 0.141). Repeated-measures ANOVA demonstrated significant group × time interactions for CRP, IL-6, PCT, and VAS scores, indicating different postoperative recovery trajectories between groups. WBC and ESR showed significant temporal changes but no significant group × time interactions.
Conclusion: Robot-assisted uniportal spinal endoscopy was associated with favorable perioperative and early clinical outcomes for patients with lumbar spondylodiscitis, suggesting its potential role in facilitating early postoperative recovery.
