Objective:To evaluate the application of titanium plate and titanium mesh in multi-segmental cervical spondylotic myelopathy anterior fixation.Methods:Twenty-five patients of multi-segmental cervical spondylotic myelopathy were treated with anterior cervical corectomy and fixation with titanium plate and titanium mesh from 1998 to 2002.Results:All the twenty-five patients of bone planted were in fusion.Titanium mesh shedding,screw loose,plate breaking were not found after follow-up for an average of twelve months.The function of nerve had been improved.

中文摘要：目的：探讨前路钛钢板加钛网植骨内固定治疗多节段脊髓型颈椎病的效果及意义，方法：总结1998年至2002年期间收治的25例有2-3个节段突出的脊随型颈椎病行前路椎体次全切术前路钛钢板加钛网植骨内固定术，结果：经平均12个月的随访，25例患者植骨全部融合，无钛网移位脱落，无螺钉松动，钢板断裂，神经功能得到了不同程度恢复。

A further advantage is the smaller pitch of the screws allowing more threads to grasp the thinner cortices.

另一项优势是螺钉较小的斜度让更多的螺纹把持薄的皮质骨。
