Active Comparator
3D printing guide plate group
Conventional guidance group
3D-printed customized guide plate will be used to guide the puncture in percutaneous disc decompression surgeries.
The surgeons would place the needle according to his/her previous experience under the guidance of C-arm fluoroscopy or CT.
