A novel guiding device for puncture localization in percutaneous transforaminal endoscopic discectomy.
Trial report in Journal of orthopaedic surgery and research, 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
backgroundConventional fluoroscopy-based positioning techniques for percutaneous transforaminal endoscopic discectomy (PTED) depend heavily on the operator’s spatial cognition and surgical expertise, typically necessitating multiple puncture attempts under iterative radiographic monitoring, which inherently involves substantial risks of iatrogenic injury and cumulative radiation exposure. This study aims to develop a simple and practical novel puncture guiding device for PTED and apply it in PTED surgery.
methodsA novel guiding device for assisting puncture localization in PTED was developed. Patients scheduled for PTED were randomly divided into two groups: Group A and Group B, with 30 cases in each group. Group A used the novel guiding device for puncture localization in PTED, while Group B used the traditional fluoroscopic puncture method. The subsequent endoscopic surgical procedures were the same for both groups. The basic data of the patients, intraoperative puncture localization evaluation indicators (number of punctures, number of fluoroscopies, puncture localization time, surgical time), and surgical efficacy evaluation indicators were recorded and compared.
resultsThe number of punctures in Group A and Group B were 4.40 ± 0.89 and 7.93 ± 2.27, with Group A having significantly fewer punctures than Group B (P < 0.05). The number of fluoroscopies in the two groups were 13.03 ± 1.13 and 20.70 ± 3.34, respectively, with Group A having significantly fewer fluoroscopies than Group B (P < 0.05). The puncture localization time in the two groups were 34.57 ± 5.52 min and 43.00 ± 6.38 min, respectively, with Group A having a shorter puncture localization time than Group B (P < 0.05). The total surgical time in the two groups were 91.00 ± 10.70 min and 99.67 ± 10.08 min, respectively, with Group A having a shorter total surgical time than Group B (P < 0.05). There were no significant statistical differences in surgical efficacy evaluation indicators between the two groups (P > 0.05).
conclusionThe novel guiding device has the advantages of being easy to use, fast and accurate in puncture, and having a high success rate. Compared with the traditional fluoroscopic puncture method, the novel guiding device can reduce the difficulty of puncture localization in PTED, improve puncture accuracy, and reduce the number of punctures, fluoroscopies, and puncture localization time.
