颈椎后路椎管扩大成形术后并发症的研究进展

RESEARCH PROGRESS OF COMPLICATIONS OF EXPANSIVE LAMINOPLASTY

目的总结颈椎后路椎管扩大成形术后并发症中发病机制尚未完全了解的轴性症状、后凸畸形、节段性运动麻痹的研究进展。方法查阅有关颈椎后路椎管扩大成形术后并发症文献,并综合分析。结果轴性症状、后凸畸形、节段性运动麻痹并发症的发病机制尚未完全了解,但已有了更多新的发现,如椎体后方肌肉韧带复合体的重要性和引起节段性运动麻痹的神经根麻痹、脊髓损伤两种学说。结论应对轴性症状、后凸畸形、节段性运动麻痹并发症的发病机制作进一步研究,以期能有效防治其发生。

Objective To review the progress in the research of complications after expansive laminoplasty such as axial symptom,kyphotic deformity,and segmental motor paralysis.Methods Recent articles about complications after expansive laminoplasty were reviewed,and comprehensive analysis was done.Results The pathogenesis of axial symptom,kyphotic deformity,and segmental motor paralysis has not yet fully been understood,but has brought new finding,such as the importance of the spinous process-ligament-muscle complex,C5 palsy theory,and the involvement of the spinal cord mechanism.Conclusion The pathogenesis of axial symptom,kyphotic deformity,and segmental motor paralysis should be further investigated to prevent and treat the complications.
