摘　　要：目的 :探讨腰椎横突平分线与椎弓根侧方平分线的关系。方法 :对 10 0套干燥腰椎骨标本横突平分线与椎弓根侧方平分线的关系及距离进行了观测。结果 :在L1有 83 .1% ,L2 73 .1% ,L372 .4% ,L4 87.5 % ,L55 4.1%的横突平分线位于椎弓根侧方平方分线下方 ,距离为L1(2 .4± 1.0 )mm ,L2 (2 .4± 0 .8)mm ,L3(2 .3± 0 .9)mm ,L4 (2 .9± 0 .8)mm ,L5(2 .3± 0 .7)mm。结论 :横突平分线多不通过椎弓根中心 ,所以横突平分线作为腰椎椎弓根螺钉的横向定位标志欠准确。Objective: To discuss the relationship between the center of the pedicle and the axis of the transverse process.Methods: The distance from the center of the pedicle to the axis of the transverse process were measured on 100 dry lumbar vertebrae specimens.Results: The axis of the transverse process are inferior to the center of the pedicle in 83.1% L 1, 73.1% L 2, 72.4% L 3, 87.5% L 4, 54.1% L 5, and the distance is 2.4±1.0 mm in L 1,2.4±0.8 mm in L 2, 2.3±0.9 mm in L 3, 2.9±0.8 mm in L 4, 2.3±0.7 mm in L 5.Conclusion: Because the axis of the transverse process does not cross the center of pedicle, it is not a ideal mark of pedicle screw entrance point.
