Clinical application of accurate lumbar pedicle screws placement assisted by 3D printing navigation modules
Objective Lumbar individualized navigation modules were used in clinic to evaluate the feasibility and accuracy. Methods we selected two adult patients with lumbar vertebral compression fracture and adopted 3D reconstruction, digital design and 3D printing to make 12 lumbar individualized navigation modules which were applied in operationin order to assist implanting lumbar pedicle screws. Then, the postoperative X-ray and CT examination were used to evaluate the efficacy of the screws implanting. Results A total of 12 lumbar pedicle screws were implanted and all of them were located within the pedicle. The success rate of implantation was 100%. Conclusion By means of digital design and 3D printing navigation modules, we can realize accurate andindividualized implanting lumbar pedicle screws.
