Risk Factors of Correction Loss After Percutaneous Reduction and Fixation for Thoracolumbar Burst Fracture: A One-Year Follow-Up Study

Year: 2025

Type: article

Abstract: Study design and purpose: This is a single-center retrospective observational study. The study aimed to find out the risk factors for correction loss after percutaneous reduction and fixation for thoracolumbar burst fractures. MATERIALS AND METHODS: This study included 25 patients who underwent percutaneous reduction and pedicle fixation for thoracolumbar burst fractures from 2017 to 2024. Radiographic assessments were performed to identify vertebral wedge and focal kyphosis angles pre-operatively, post-operatively, and at one-year follow-up for all patients. Then, patients were divided into two groups: no correction loss (Group NCL), which had <5 degrees of correction loss, and correction loss (Group CL), which had 5 and >5 degrees of correction loss at one-year follow-up. Between the two groups, radiological parameters, BMI, osteoporosis, long/short construct, surgical time, intraoperative blood loss, postoperative complications, and revision surgery rate were evaluated. In comparing the groups, the Mann-Whitney U test analysis was used for continuous variables, while the Fisher exact test was used for dichotomous variables. RESULTS: <0.001), but decreased at final follow-up (p<0.001). The BMI, osteoporosis, long/short construct, surgical time, intraoperative blood loss, and postoperative complications were not significantly different. No revision surgery was observed in either group. CONCLUSIONS: Percutaneous reduction and fixation for thoracolumbar fractures could correct and maintain good spinal alignment. The preoperative large vertebral wedge angle was the only risk factor for correction loss. Short fixation, osteoporosis, and vertebral comminution were not significant risk factors in our study.
