Application of the guidewire anchoring technique in lateral approach transforaminal endoscopic lumbar foraminoplasty: a propensity score-matched retrospective study.

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
Objective: Safe and rapid bony localization for intervertebral foraminoplasty is essential in lateral transforaminal endoscopic lumbar discectomy (TELD). This study introduces a novel guidewire anchoring puncture technique and compares it with conventional puncture to evaluate operative efficiency, safety, and clinical outcomes. Methods: A retrospective 1:1 propensity score-matched (PSM) analysis was performed on 60 patients with single-level L4/5 or L5/S1 disc herniation receiving TELD (anchoring group = 30, conventional group = 30). Baseline demographics, intraoperative metrics, neurological complications, and serial Oswestry Disability Index (ODI)/leg pain Numeric Rating Scale (NRS) scores (preoperatively, 1-day, 3-month, 12-month postoperatively) were compared. Results: Baseline characteristics were balanced after PSM (all standardized mean differences < 0.1). The anchoring group exhibited significantly shorter total operative time, superior articular process (SAP) foraminoplasty time, and fewer fluoroscopic exposures (all Conclusion: The guidewire anchoring technique improves TELD foraminoplasty efficiency and reduces intraoperative radiation and neurological complication risk. However, given the single-center, small-sample, 12-month limited follow-up design, its broad clinical adoption requires further multicenter prospective validation. Both techniques deliver equivalent clinically meaningful long-term pain relief.
