微形钛板固定颈椎椎板成形术的临床应用

Clinical application of cervical laminoplasty with Ti-mesh plates

[目的]介绍一种颈椎后路开门、微形钛板固定的椎板成形术式,评价其在颈椎椎管狭窄手术中的应用效果。[方法]选择27例颈椎管狭窄症患者实施颈椎后路单侧或双侧开门减压、微形钛板固定开门椎板的新术式,术后平均随访27个月。[结果]27例患者切口均达到一期愈合,术后随访半年以上症状改善优良率88%,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1例出现继发性椎管狭窄。[结论]应用微形钛板固定的颈椎椎板成形术具有避免开门椎板再关闭,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。

[ Objective] To introduce cervical laminoplasty fixation with Ti-mesh plates in posterior open door decompression and evaluate its clinical outcomes. [ Method] A total of 27 cases with cervical spinal stenosis were treated by laminoplasty with mini titanium plates. The mean following-up time were 18 months. [ Result ] All cases were primary healed, the preoperative symptoms were improved satisfactorily with 88% good to excellent outcome over 6 months following-up. One case without relief of nurological symptoms underwent an additional anterior multilevel corpectomy. The surgical lamina achieved bone fusion without stenosis. [ Conclusion ] The laminoplasty with Ti-mesh plates restore spinal posterior construction with less loss of range of motion and maintain larminar in open position without stenosis. The surgical procedure is easier to perform with less complication rates.
