椎板螺钉胸腰椎椎管重建术

Thoracolumbar canal reconstruction with lamina complex re-implantation fixed by laminar screws

摘要:

[目的]介绍椎板螺钉胸腰椎椎管重建术的手术技术和初步临床效果。[方法]对 17 例胸腰椎椎管内肿瘤患者行肿瘤切除后椎管重建术。于肿瘤所在节段行全椎板切除，显露椎管，切除肿瘤，将切下的棘突椎板复合体行原位回植，恢复骨断端对应关系，用椎板螺钉固定重建椎管。[结果]17 例患者均顺利完成手术，无严重并发症。随访 12~18 个月。末次随访时，所有患者骨断端均无明显塌陷移位并获得良好骨性愈合，症状均较术前明显改善。[结论]棘突椎板复合体原位回植椎板螺钉固定椎管重建术简单实用，有其特有优势，短期内可取得满意的临床疗效。

Abstract:

[Objective] To introduce the surgical technique and preliminary clinical results of thoracolumbar canal reconstruction with lamina complex re-implantation fixed by laminar screws. [Methods] A total of 17 patients underwent abovesaid surgical treatment after re- section of introspinal tumors in our hospital. The entire autologous spinous process-lamina complex was completely removed to expose canal before the resection of the tumor. The entire autologous spinous process-lamina complex was reimplanted to restore corresponding spinal structure, and were fixed by laminar screws. [Results] All patients had operation performed smoothly without serious complications, and fol- lowed up 12~18 months. At the latest follow-up, all the patients got significant improvement in symptoms, without displacement and col- lapse of re-implanted spinous process-lamina complex. [Conclusion] Thoracolumbar canal reconstruction with autologous spinous processlamina complex re-implantation fixed by laminar screw is simple and feasible technique with unique advantages and does achieve satisfacto- ry clinical outcomes in short term.
