颈椎单开门OsteoMed M3钉板内固定椎管扩大成形术的临床应用

目的 介绍一项新技术在颈椎单开门椎管扩大成形术中使用OsteoMed M3钉板内固定,评价其在颈椎疾患手术中的应用效果.方法 选择多节段椎间盘突出并椎管狭窄等颈椎疾患16例,行颈椎单开门OsteoMed M3钉板内固定椎管扩大成形手术治疗,术后随访半年以上.结果 16例患者全部得到随访,术后随访半年以上,术前JOA评分:9.06±2.380(5~13),术后JOA评分:13.63±1.408(11~16),差异有统计学意义(P<0.005),大部分病人症状明显改善,术后改善率57.5%.1例症状改善不明显的患者,二期实施前路减压固定融合术后症状缓解,无一例出现继发性椎管狭窄.结论 在颈椎单开门椎管扩大成形术中应用OsteoMed M3钉板内固定具有避免开门后再关闭,保持椎管扩大效果,同时对脊柱活动度影响小的优点,且操作简单,并发症少,适合临床运用.
