【摘要】 目的:为临床椎弓根钉植入的安全性提供客观依据。方法:采取 Maged 法和"人" 字嵴法,将临床应用的真实螺钉,分别植入两侧椎弓根。在20具脊柱标本上对 T₁₁～L₂椎弓根钉道壁进行测量。结果:上、下钉道壁厚度间无统计学差异内,外侧壁在穿透率和厚度上均有统计学差异。结论:①从钉道内、外侧壁的厚度方面论证其对植钉安全性的重要意义。②从穿透率和钉道壁厚度的角度,论证了 T₁₁、T₁₂应用 Magerl法,L₁、L₂应用人字嵴法即不同节段应用不同方法的临床解剖学依据。更多还原

【Abstract】 Objective:To measure the wall of pedicle screw path in thoracolumbar spine,It is benefit to the clinic.Method:We use the magerl technique and the"Λ"shape crest technique to in- sert the pedicle screw with the truely clinical screw in every pedicle of T₁₁-K₂ vertebral,The wall of pedicle screw path was measured with slide gaud.Result:The parameter of the superior and inferior wall has no variety the violation ratio the pedicle screw path and the parameter of the medial and later- al wall have varieties.Conclusion:①the parameter of the medial and lateral wall has much significance for the safely insertion;①As far as it is the violation ratio and the parameter of the pedicle screw wall, we conalude that our result is the clinical anatomic basion about the T₁₁-L₁₂with magerl technigue and the L₁～L₂ with the"Λ"shape crest technique.更多还原
