Application of visible simulation surgery in the typeⅡB odontoid fractures / 局解手术学杂志

ABSTRACT

Objective Through the exploration of the reality technology to find the treatment of type Ⅱ odontoid fractures in anterior fixation of odontoid fractures with hollow screw .Methods Based on 64 row spiral CT continuous 2-dimensional images of akull ,atlas and axis were reconstructed by the Mimics software ,Mimics software reconstruction atlas ,the atlantoaxial 3D visualization structure in Mimics, simulated surgery was carried out in the MedCAD .Results The structure of three-dimensional reconstruction image was clear ,structure of hollow screw into pin-point was accurate in virtual simulation surgery ,the screw path is correct .Conclusion Mimics Software has great val-ues in the diagnosis of odontoid fractures ,preoperative risk evaluation ,place the hollow screw and clinical teaching ,which provides an objec-tive basis for choice of treatment program .
