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.
子房卵球形或球状；柱头2或3(- 5)，通常下弯，整个具乳突。
Ovary ovoid or globose; stigmas 2 or 3 (-5), usually recurved, papillate throughout.
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.
