Background: 3D printers have increased surgical success by providing preoperative simulation of complex surgical approaches. Individualized 3D printed model used many fields of neurosurgery. We present 3D printed model assisted posterior internal fixation of C2 type III fracture.
Methods: 64 year old male patient was admitted to emergency service after vehicle accident. The patient had severe neck pain but no neurological deficits. After computed tomography scanning, C2 type III fracture found.We planned individualized 3D printed C1-C2 model to reduce complications and improve the success. We used Fused Deposition Modeling(FDM) 3D printer. The material used in FDM 3D printers is a rigid thermoplastic wrapped in rolls, called a filament. The filament is thinned to a thickness of 0.4 mm through a hot nozzle tip and layers are formed with this thin plastic.After 3D modelling we performed surgery preoperatively on this model.
Results: The patient was placed prone with the head fixed in the head holder. The posterior internal fixation procedure was performed by using a C1 lateral mass screw, a C2 pedicle screw. There was no complication and short surgery time. Patient discharged postoperative 4th day.
Conclusion: Individualized 3D printed model assisted C1-C2 fixation is effective in C1 -C2 fractures. 3D printed models has many advantages, including preoperative simulation, intraoperatve guidance, and peroperative complications.
