露需要融合的颈椎及胸椎椎体.将切口横向

至颈椎椎间关节的外侧面以及胸椎的横突位置.向头端至枕外隆凸(EOP)移除软组织\关节面\椎板去皮质,选择理想进钉点.术前CT可显示弓根大小及方向,为减少固定钛棒的弯曲,尽可能保证螺钉排列位于一条直线上安放螺钉钻孔

先决定钻孔的深度.按压钻孔导向器上的按钮,安装套管,可调节钻孔深度,每2mm递增.

(黑色适用于8-16mm,白色适用于16-30mm)将钻孔导向器放置在进钉点,

直径2.4mm的钻头,并开始钻孔.测量钻孔深度,根据所测深度选择相同长度的螺钉再次将钻孔导向器放置在进针点,

直径3.5mm的丝攻,保持相同的角度,进行攻丝.选择合适长度的螺钉,植入.偏角螺钉:提供额外15度的角度,以适合不同

的解剖结构,适用于大角度偏角固定的区域,螺钉呈绿色.螺钉头部的凹槽显示偏角的方向置棒枕骨钛板的大小,是由纵向放置在枕骨上的钛棒间距离决定,所以需要先裁减合适长度钛棒,并弯棒,以至于棒的一端可以轻易放置进各个方向的万向螺钉,另一端可伏帖的放于枕骨表面将钛板放置在枕外隆凸和枕骨大孔之间的中线上Y型钛板必须倒置安放,单头朝上,位于EOP下方中线,其余对称的2头,必须放置在大孔上方,以便在钛板的尾端植骨T型钛板放置在靠上的部位,单头向下,位于
