Results and complications of vertebrectomy with posterior approach after 2-year follow-up

OBJECTIVE: To describe the surgical technique for vertebrectomy by posterior single approach in the thoracic and thoracolumbar spine with circumferential reconstruction and arthrodesis, and evaluate retrospectively the results and complications after 2 years of follow-up in patients undergoing this technique.METHODS: Retrospective analysis of medical records and imaging studies of 12 patients with vertebrectomy indication for various pathologies, undergoing this surgical technique.RESULTS: Eight (66.67%) patients were male and four patients (33.33%) were females aged 13-66 years (mean 40 years). There were nine patients with involvement of the thoracic spine and three of the lumbar, and one patient with two consecutive vertebrae affected. All patients had improved or remained with the neurological condition. Surgical complications were two cases of hemothorax, two cases of loosening of the screws, one of them requiring surgical revision, and a case of material failure and pseudarthrosis.CONCLUSION: Vertebrectomy by posterior approach in thoracolumbar spine with circumferential reconstruction and fusion can be performed safely for a variety of indications.

【研究目的】描述胸段及胸腰段脊柱经后入路单一术式行椎体切除术（vertebrectomy）联合环形重建与关节融合术（arthrodesis）的手术操作技术，并对接受该术式的患者开展为期2年的随访，回顾性评估其手术疗效与并发症发生情况。【研究方法】对12例因各类病变符合椎体切除术适应证并接受该手术术式的患者的病历资料与影像学检查结果进行回顾性分析。【研究结果】本研究纳入的患者中，男性8例（占比66.67%），女性4例（占比33.33%），年龄范围为13~66岁，平均年龄40岁。其中9例患者累及胸段脊柱，3例累及腰椎，另有1例患者存在2个连续椎体受累。所有患者的神经功能状态均得到改善或保持稳定。手术相关并发症包括2例血胸（hemothorax）、2例螺钉松动，其中1例需行手术翻修，以及1例内固定材料失效与假关节形成（pseudarthrosis）。【研究结论】针对多种手术适应证，胸腰段脊柱经后入路行椎体切除术联合环形重建与融合术可安全开展。
