摘　　要：目的将腰椎个体化导航模块应用于临床,评价导航模块的可行性及精确性。方法选取2例成年腰椎压缩型骨折患者,通过三维重建腰椎模型、数字化设计导航模块和3D打印,制造12个腰椎个体化导航模块,术中应用个体化导航模块辅助植入腰椎椎弓根螺钉12枚,通过术后X线和CT检查,评价螺钉植入效果。结果共植入12枚腰椎椎弓根螺钉,全部12枚螺钉均位于椎弓根内,植入准确率为100%。结论基于数字化设计的3D打印导航模块,可实现个体化的腰椎椎弓根螺钉精确植入。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.
