Whole process navigated percutaneous endoscopic lumbar discectomy guided by a novel X-ray instant navigation: a technical report and preliminary clinical outcomes.
Article in BMC musculoskeletal disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveIn this study, we established a rapid whole-process Percutaneous Endoscopic Lumbar Discectomy(PELD) surgical workflow guide by a novel X-ray instant Navigation(XIN)based on permanent calibration and specialized instruments. The safety and efficacy of this technique were evaluated through clinical application on surgical treatment in patients with lumbar disc herniation.
methodsFrom June 2023 to February 2024, 44 patients with lumbar disc herniation underwent PELD guided by XIN system. A retrospective review of clinical data was conducted, including navigation preparation time, cannulation time, total operative time, intraoperative fluoroscopy exposure, and hospital stay duration. Outcomes were assessed using the Visual Analog Scale (VAS) for back and leg pain, the Oswestry Disability Index (ODI) for functional status, and the modified MacNab criteria for overall efficacy.
resultsThe average surgical time was 50.29 min (range: 32-71 min), with an average navigation preparation time of 2.57 min and cannulation placement time of 12.70 min. The average postoperative hospital stay was 1.39 days (range: 1-3 days). The average intraoperative fluoroscopy count was 3.41 times. At the final follow-up, significant improvements were observed in both the VAS scores for back and leg pain and ODI functional impairment index compared to preoperative values, with statistically significant differences (P < 0.001). According to the Modified MacNab criteria,27 cases (61.4%) were rated as excellent, 13 cases (29.5%) as good, 3 cases (6.8%) as fair, and 1 patients (2.3%) as poor, resulting in an overall excellent/good rate of 90.9%. No cases of nerve root injury or deep infection occurred.
conclusionWe developed a whole process navigated PELD technique, incorporating specialized instruments and a streamlined procedural workflow based on X-ray instant navigation (XIN). Preliminary clinical results demonstrate that this technique is safe, efficient, and effective.
