计算机辅助导航热塑膜定位固定无移位髋臼后柱骨折的实验研究

目的 评估应用计算机辅助热塑膜定位系统微刨置入螺钉固定髋臼后柱骨折的准确性和有效性. 方法应用计算机辅助热塑膜定位系统将20枚空心钉置人10具标本的髋臼后柱.置入螺钉后,通过CR、CT检查螺钉的位置.结果 在计算机辅助热塑膜定位系统辅助下,直接置入螺钉,20枚髋臼后柱螺钉均在安全区内. 结论计算机辅助热塑膜定位系统为微创置入髋臼后柱螺钉提供准确的窄间定位和稳定的路径导航,操作时手术创伤明显减少,具备较好的安全性和准确性,为进一步应用于临床奠定了基础.

Computer.assisted thermoplastic elustomer film localization system for screw insertion to fix posterior column of acetabulum

Objective To assess accuracy and efficacy of the mini-invasive screw insertion for fix-ation of the posterior column of acetabulum by the computer-assisted thermoplastic elastomer film localization system. Methods In a simulated surgical setup, 20 cannulated screws were placed into the posterior column of acetabulum in 10 corpses under the guidance of the computer-assisted thermoplastic elastomer film localization system. The positions of the screws were checked with CR and CT. Results All the 20 screws were in the safe area. Radiation exposure was totally avoided. Conclusion The system can pro-vide precise, effective and safe navigation for screw insertion to fix the posterior column of acetabulum, and markedly prevent the patient and the staff from exposure to the radiation.
