Abstract Objective To study 3D printing guide system on puncture accuracy and fluoroscopic exposure as well as surgical efficiency of transforaminal percutaneous endoscopic lumbar discectomy (PELD).Methods Four patients with Lumbar disc herniaion, admitted to our hospital from October 2016 to February 2017 and aged from 45 to 78 years old (with the average age of 58.5),including 2 males and 2 females,were chosen as study objects.The 3-dimensional image was obtained with Mimics Medical 17.0 software.A perfectly personal navigation module included puncturing-guidance-channel was designed and printed by 3D-printing technology.The printing module was tested in surgery.The module was tightly attached to the puncturing area, and the puncturing was performed following the guide system during the surgery. The accuracy of the needle was observed with the C arm X-Ray machine.Results All the 4 patients successfully received surgery.Intraoperative fluoroscopy showed satisfied results which were classified based on accuracy: 2 highly accurate results, one qualified result and one acceptable result. No puncture failure and no injuries of important organs or blood vessels were found.Conclusion 3D printing guide system can significantly improve the puncture accuracy of PELD and reduce its fluoroscopy exposure as well as operation time, which indicates its great potential in the future clinical applications.
