Abstract:
Objective A design of guide wire localization apparatus for the internal fixation of dens fractures. Methods From October 1999 to February 2000, 5 cases of dens fractures were treated by anterior internal fixation using cannulated compression screws; 4 cases were of Anderson typeⅡ and 1 case was typeⅢ . The guide wire localization apparatus was used for all of the patients during operations. Results The operating time was 2 to 2.5 hours, averaging 2 hours 15 minutes. The amount of bleeding was 20 to 100 ml, averaging 60 ml. The time of follow-up was 5 to 9 months, averaging 6.7 months. The locations of all the 5 cannulated compression screws were excellent, positioning in the center of the odontoid process without deviation. 4 cases healed normally and 1 had delayed bone healing. Conclusion The use of a guide wire location apparatus increased the accuracy of internal fixation of screws in dens fracture, decreased X-ray to radiation to the bodies, and reduced the possibility of pollution in operation.
