Objective: This study aims to evaluate the clinical benefits of the integrated optical and magnetic surgical navigation system in assisting transforaminal endoscopic lumbar discectomy (TELD) for the treatment of lumbar disc herniation (LDH). Methods: A retrospective analysis was conducted on patients who underwent TELD for LDH at Beijing Chaoyang Hospital, Capital Medical University from November 2022 to December 2023. Patients treated with the integrated optical and magnetic surgical navigation system were defined as the navigation-guided TELD (Ng-TELD) group (30 cases), while those treated with the conventional x-ray fluoroscopy method were defined as the control group (31 cases). Record and compare baseline characteristics, surgical parameters, efficacy indicators, and adverse events between the 2 patient groups. Results: The average follow-up duration for the 61 patients was 11.8 months. Postoperatively, both groups exhibited significant relief from back and leg pain, which continued to improve over time. At the final follow-up, patients’ lumbar function and quality of life had significantly improved compared to preoperative levels (p < 0.05). The Ng-TELD group had significantly shorter total operation time (58.43 ± 12.37 minutes vs. 83.23 ± 25.90 minutes), catheter placement time (5.83 ± 1.09 minutes vs. 15.94 ± 3.00 minutes), decompression time (47.17 ± 11.98 minutes vs. 67.29 ± 24.23 minutes), and fewer intraoperative fluoroscopies (3.20 ± 1.45 vs. 16.58 ± 4.25) compared to the control group (p < 0.05). There were no significant differences between the groups in terms of efficacy evaluation indicators and hospital stay. At the final follow-up, the excellent and good rate of surgical outcomes assessed by the MacNab criteria was 98.4%, and the overall adverse event rate was 8.2%, with no statistically significant differences between the groups (p > 0.05). Conclusion This study demonstrates that the integrated optical and magnetic surgical navigation system can reduce the complexity of TELD, shorten operation time, and minimize radiation exposure for the surgeon, highlighting its promising clinical potential.

Objective To assess the radiography change of lumbar spinal stenosis (LSS) treated with the implantation of Coflex interspinous device retrospectively.Methods Sixty patients (34 male and 26 female) with LSS who underwent the decompression and Coflex device implanted surgery from January 2010 to December 2013 were followed up.The mean age of the patients was 59.4 years.There were 33 cases underwent Coflex surgery and 27 cases underwent Topping-off surgery.The Coflex segment ranged from L1/2 to L4/5 (L1-2:1,L2_3:5,L3_4:19,L4_5:35).The foraminal height,foraminal width and intervertebral space height change of the Coflex segment as well as its adjacent segment were recorded pre-/post-operatively and at last follow-up.Meanwhile,the Oswestry Disability Index (ODI) and Visual Analog Scale(VAS) were measured in all patient pre-/post-operatively and at last follow-up.The measurement data was recorded as ~ ± s.And the independent and paired samples t-test was used to conduct the statistical analysis.Results The foraminal height(FH) increased from (19.82 ± 2.38) mm to (22.28 ± 2.95) mm (P ＜ 0.05) post-operatively,and the FH decreased to (19.31 ± 3.32) mm at the last follow up(P ＞ 0.05,compared to the post-operation).The average foraminal width (FW) was 11.2 mm,11.58 mm and 11.12 mm at pre-/post-operation and follow up,which had no significant different change(P ＞0.05).The post-operative intervertebral space height (ISH) increased from (7.84 ± 1.56) mm to (10.05 ±2.39) mm (P ＜0.05),and the ISH decreased to (7.91 ± 1.77) mm at the last follow up(P ＞0.05,compared to the post-operation).The amount of the decreased FH and ISH had no significant difference when comparing the Coflex segment with its adjacent (Coflex ± 1) segments (P ＞ 0.05).The lumbar lordosis (LL) was 43.13° ± 15.93°,38.41° ± 10.82° and 43.10° ± 13.21° at pre-/post-operation and follow up,there was no significant difference between pre-and post-operation (P ＞ 0.05).All patients showed statistically significant improvement(P ＜ 0.05) in the clinical outcome assessed in the VAS and ODI at the time of follow up compared to the pre-operation.The ODI score decreased from 65.12 ± 13.56 to 9.89 ± 1.77; the VAS score decreased from 8.02 ± 1.81 to 1.66 ± 0.51.Conclusions Coflex device could temporarily improve the FH and ISH after operation.However,it could not maintain the improvement as the follow-up time extended.The surgical decompression is the responsible factor for the good clinical outcome but not the improvement of FH.
