摘要
目的 比较瞄准器法和直视法置入经椎板螺钉的结果。方法 20具腰段脊柱标本（T12～S1），在左侧采用瞄准器、在右侧直视下钻孔，然后置入直径4．0mm螺钉作为经椎板螺钉，观测椎板穿破率和穿破程度。结果 瞄准器法和直视法置入螺钉的椎板穿破率分别为37．04％和41．67％，穿破程度均小于2mm，经秩和检验，两者差异无显著性意义（P〉0．05）。结论 瞄准器法或直视法在国入腰段脊柱置入直径4．0mm螺钉作为经椎板螺钉，均较为安全、可行。
Objective To observe results of placement of translaminar screw in two methods. Methods Twenty specimens of lumbar spine were used. On the left, an aim - sighting device was used while on the right, the direct visualization was used for drilling the holes. Results The penetration rates of laminar for methods of the aim - sighting device and the direct visualization were 37.04 % and 41.67 % respectively. The penetration depth was all no more than 2 mm. There was no statistically significant difference between the two methods （P 〉 0.05 ）. Conclusion It is indicated that any method by the aim- sighting device or under the direct visualization, is relatively safe and feasible for placement of translaminar screws of 4.0 mm in diameter in the lumbar spine of the Chinese.
