枕颈融合固定在颅颈部畸形手术中的应用
|
Abstract:
目的 · 研究枕颈融合固定在颅颈交界处畸形治疗中的应用。方法 · 在诱发电位监测下对36 例颅颈交界处畸形行枕颈部减压, 术中采用 Vertex 枕骨钉 – 椎板钩系统固定 16 例,Vertex 螺钉 – 钛棒系统固定 11 例,Mountaineer OCT 系统固定 9 例。术后随访 2 ~ 12 年 ( 平均 7 年 ),依据颈椎 JOA?评分表对术后患者进行评分。结果 · 全部病例获得随访。与术前比较,影像学资料显示术后 9 个月植骨 融合率达100%。无内固定棒钉断裂及脱钩现象。JOA 评分结果显示:治愈24 例(66.7%),显效4 例(11.1%),有效8 例(22.2%), 无效 0 例。结论 · 枕颈固定融合有助于恢复颅颈交界区的稳定性。术前完善的影像学资料、明确的手术指征、合适的术式及内固定材 料,是患者获得良好预后的关键。
