Abstract Objective To develop a novel puncture localization device and evaluate its application value in assisting puncture localization in lumbar intervertebral foramen surgery.Methods A right triangle can be constructed in the three-dimensional space of the lumbar spine，and the hypotenuse was that the ideal puncture path for the posterolateral approach.According to this principle，a puncture positioning device was developed to assist surgery.From June 2020 to April 2021，there were 64 patients diagnosed with single segment lumbar disc herniation and underwent percutaneous transforaminal surgery in the orthopedic department of Wuzhou Red Cross Hospital，including 34 males and 30 females.The age range was 22~79 years，with an average of (55.15±16.42) years old.Patients were randomly divided into a puncture positioning device group and a traditional group that completed puncture positioning with freehand technqiue under C-arm fluoroscopy.Among them，the device group had 34 cases and the traditional group had 30 cases.We compare the puncture frequency，puncture time，fluoroscopy frequency，visual analogue scale(VAS) pain score，Japanese Orthopaedic Association (JOA) score，and Oswestry Disability Index (ODI) of two groups of patients at specific times before and after surgery.Results The puncture frequency，puncture time，and fluoroscopy frequency of the positioning device group were all lower than those of the traditional group，with a statistically significant difference (P＜0.05).The JOA score and ODI index of the two groups of patients improved significantly at 1 day and 6 months after surgery compared to before surgery (P＜0.05)；There was no statistically significant difference in VAS score，JOA score，and ODI index between the two groups (P＞0.05).Conclusion Right triangle measurement can be used as a new preoperative design method.The application of this new puncture positioning device in lumbar intervertebral foramen endoscopic surgery can reduce the number and time of punctures，improve accuracy，and is particularly suitable for beginners.
