颈前路椎间盘切除椎间融合器融合术加颈后路单开门术治疗脊髓型颈椎病

Clinical application of anterior cervical discectomy and interbody fusion and posterior cervical spine canal open-door laminoplasty in cervical spondylotic myelopathy

[目的]探讨颈椎前路椎间盘切除椎间融合器融合术加颈椎后路单开门椎管扩大成形术治疗脊髓型颈椎病在临床上的应用价值。[方法]应用CervicalCage行颈椎前路椎间盘切除椎间融合术,同时,颈椎后路行单开门椎管扩大成形术11例,平均随访6个月。按40分法和JOA评分对手术前后脊髓功能进行评分,并测量颈椎术前术后前柱高度及椎管宽度和进行相关性分析。[结果]颈椎前路椎间盘切除椎间融合器融合术加颈椎后路单开门椎管扩大成形术,明显改善脊髓型颈椎病的脊髓功能。40分法平均37分,改善率83%;JOA评分16.5分,改善率91%;前柱高度平均增加1.28mm;椎管宽度平均增加2.22mm。[结论]颈椎前路椎间盘切除椎间融合器融合术加颈椎后路单开门椎管扩大成形术,有效恢复了颈椎前柱高度、增加椎管宽度,明显改善了脊髓型颈椎病的脊髓功能。

[ Objective ] To evaluate the value of anterior cervical discectomy and interbody fusion and posterior cervical spine canal open-door laminoplasty in cervical spondylitic myelopathy. [ Methodl Eleven patients underwent anterior cervical discectomy and interbody fusion and posterior cervical spine canal open-door laminoplasty using Cervical Cage with average follow-up of 6 months. The spondylotlc function was evaluated by forty points of JOA score and correlation study between anterior column height and spine canal width. [ Result ] The anterior cervical discectomy and interbody fusion and posterior cervical open-door laminoplasty significantly improved the spondylotic function. The score were separately 37 and 16, 5 after operation by 40 points of JOA score and the improving rate were separately 83% and 91%. The anterior column height and spine canal width increased average 1.28 mm and 2. 22 mm separately. [ Conclusion] The anterior cervical discectomy and interbody fusion and posterior cervical spine canal open-door laminoplasty can resort the anterior column height, increase the spine canal width and significantly improve the spondylotic function.
