This retrospective study investigated the early results of a single-stage posterolateral transpedicular corpectomy and fusion in the thoracolumbar spine. A modified technique with nerve preservation and bilateral expandable cage implantation is described. Four patients with vertebral metastasis and one patient with vertebral osteomyelitis were included in this series. Two patients underwent two level corpectomies, whereas three patients underwent single level corpectomy. The mean follow-up was 3.3 months. No perioperative complication was encountered. Improvement in neurological status was observed in patients with preoperative neurological deficits. Vertebral height and sagittal and coronal deformity were corrected using the current technique. Bilateral cage implantation offers an additional advantage of asymmetrical reconstruction of the ventral column in cases of hemicorpectomy. Single-stage posterolateral transpedicular corpectomy and fusion is a useful approach to treat ventral thoracolumbar pathologies.
本回顾性研究探讨了胸腰椎后路经皮单节段椎体次全切除融合术的早期结果。描述了一种改良的神经保护技术和双侧可扩张 cage 植入技术。本研究纳入了 4 例椎体转移瘤患者和 1 例椎体骨髓炎患者。其中 2 例患者行两节段椎体次全切除，3 例患者行单节段椎体次全切除。平均随访时间为 3.3 个月。无围手术期并发症。术前存在神经功能缺损的患者神经功能状态得到改善。采用当前技术可矫正椎体高度及矢状面和冠状面畸形。对于半椎体切除，双侧 cage 植入可提供额外的优势，即不对称重建前柱。后路经皮单节段椎体次全切除融合术是治疗胸腰椎腹侧病变的有效方法。
