Abstract：【Objective】The individualized bionic artificial lamina of titanium alloy was made by 3D printing technique. The feasibility of implantation was discussed through the model of lumbar laminectomy. 【Methods】A sample of adult lumbar vertebrae was selected, and the titanium alloy bionic artificial plate was printed in 3D. The lumbar vertebral laminectomy and implantation were performed and the cortical bone trajectory screw and locking screw technique were used to fix it. Afterwards the stability was observed. Finally, CT scan was applied to understand the condition of artificial lamina and screws. 【Results】The morphology of bionic spinal lamina designed in this study was similar to the original lamina structure. It was easy to install and matched well in simulated surgery. The use of cortical bone trajectory screw technique to fix the bionic lamina showed good stability. The retained spine and interspinous ligaments were reconstructed to the suture hole of artificial lamina spinous process. The results of CT scan showed that the designed artificial lamina was similar to the original spinal spinous process lamina, with good matching, ideal position of fixation screw and significant increase in the volume and anteroposterior diameter of osseous spinal canal after surgery. 【Conclusion】The individualized bionic artificial lamina designed by 3D printing technique can increase the volume of spinal canal after lumbar laminectomy, whose compatibility and stability are good. It has the advantages of retaining the motion of spinal segment and providing posterior ligament attachment point reconstruction.
