Abstract

Objective: The goal of this study was to evaluate the feasibility of the fractured vertebra antedisplacement reconstruction technique for the treatment of posttraumatic thoracolumbar kyphosis (PTK).

Methods: A total of 22 patients with PTK who were treated with the fractured vertebra antedisplacement reconstruction technique were retrospectively analyzed. The radiological evaluation included global kyphosis, thoracolumbar angle, and sagittal vertical axis. The clinical evaluation included visual analog scale pain score, Oswestry Disability Index score, SF-12 Health Survey score, and American Spinal Injury Association grade. The complications were recorded.

Results: The mean global kyphosis was 55.0° ± 12.6° preoperatively, 8.5° ± 5.0° postoperatively, and 10.3° ± 4.8° at the latest follow-up (p < 0.001). The average total kyphosis correction achieved was 44.7° ± 14.2°, with a range of 23.4°-79.4°, indicating a mean final correction of 80.1%. The mean thoracolumbar angle was 46.2° ± 13.2° preoperatively, 6.6° ± 4.5° postoperatively, and 7.6° ± 4.2° at the latest follow-up (p < 0.001). The mean sagittal vertical axis was improved significantly, from 51.1 ± 24.2 mm preoperatively to 28.5 ± 17.4 mm at the latest follow-up (p = 0.001). One patient (4.5%) experienced single intervertebral fusion nonunion, and 1 patient (4.5%) experienced distal screw loosening. No patients experienced any neurological deterioration. The visual analog scale pain score, Oswestry Disability Index score, SF-12 Health Survey score, and American Spinal Injury Association grade achieved significant improvement at the latest follow-up.

Conclusions: Fractured vertebra antedisplacement reconstruction technique can effectively correct kyphosis, reconstruct spinal stability, and improve the patient's symptoms and neurological function. This technique is safer, minimally traumatic, and less technically demanding to avoid osteotomy-related complications. It is a feasible treatment choice for PTK.

椎体骨折反移位重建技术：创伤后胸腰椎后凸的可行治疗选择。

研究目的本研究旨在评估骨折椎体反移位重建技术治疗创伤后胸腰椎后凸（PTK）的可行性：方法：回顾性分析了22例采用椎体骨折反移位重建技术治疗的胸腰椎后凸患者。放射学评估包括整体后凸度、胸腰椎角度和矢状纵轴。临床评估包括视觉模拟量表疼痛评分、Oswestry残疾指数评分、SF-12健康调查评分和美国脊柱损伤协会分级。并对并发症进行了记录：结果：术前平均整体后凸为 55.0° ± 12.6°，术后为 8.5° ± 5.0°，最近一次随访时为 10.3° ± 4.8°（P < 0.001）。脊柱后凸的平均总矫正度为（44.7° ± 14.2°），矫正范围为 23.4°-79.4°，平均最终矫正率为 80.1%。术前平均胸腰椎角度为（46.2° ± 13.2°），术后为（6.6° ± 4.5°），最近一次随访时为（7.6° ± 4.2°）（P < 0.001）。平均矢状纵轴明显改善，从术前的 51.1 ± 24.2 毫米降至最近一次随访时的 28.5 ± 17.4 毫米（p = 0.001）。一名患者（4.5%）出现单个椎间融合不愈合，一名患者（4.5%）出现远端螺钉松动。没有患者出现神经功能恶化。视觉模拟量表疼痛评分、Oswestry残疾指数评分、SF-12健康调查评分和美国脊柱损伤协会分级在最近的随访中均有显著改善：结论：骨折椎体反移位重建技术能有效矫正脊柱后凸、重建脊柱稳定性，并改善患者的症状和神经功能。该技术更安全、创伤小、技术要求低，可避免截骨术相关并发症。它是治疗 PTK 的可行选择。
