结果棘突钢丝在屈伸和侧弯时的运动范围可恢复完整颈椎水平，但旋转时的运动范围比完整颈椎大。
Results The range of motion (ROM) of process wire was less than that of the intact in flexion, extension, lateral bending, but not in axial rotation.
棘突钢丝固定在前屈运动方向上可加强节段的稳定性，可恢复节段在后伸、侧弯和轴向旋转运动方向上的稳定性；
The stability with wire fixation was greater and equal to in flexion and in extension, lateral bending and axial rotation respectively.
