RESUMO
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 .
RESUMO
Objective Through the exploration of virtual simulation surgery to find a way to treat lumbar spinal metastases. Methods Based on 64 row spiral CT continuous 2-dimensional images of lumbar segments, normal lumbar vertebral, destruction of disease, abdominal aorta and kidneys were reconstructed by the Mimics software. 3D visualization structure was contemplated by anterior lesions clear, titanium mesh of bone cement support, and posterior pedicle screw fixation. Results The three-dimensional reconstruction distinctly displayed the structures of lumbar and its adjacent organs, and the entire virtual simulation surgery was intuitive. Conclusion The application of virtual simulation surgery ensures more accurate 3D model of lumbar establishment and its adjacent organs, and it provides an objective basis for in-dividualized treatment programs.
