Unilateral Biportal Endoscopic Decompression for Degenerative Lumbar Spinal Stenosis Under Local Anesthesia in Elderly Patients with Medical Comorbidities.
Article in Orthopaedic surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveConventional Unilateral Biportal Endoscopic (UBE) surgery usually requires general anesthesia (GA), which introduces additional risks to patients with significant medical comorbidities. This article explores the use of UBE decompression under local anesthesia (LA) in elderly patients with severe medical comorbidities treated at our institution, providing valuable clinical insights for the application of this technique.
methodsA retrospective analysis was conducted on patients clinically diagnosed with lumbar spinal stenosis (LSS) at our center between November 2021 and March 2024, who underwent UBE decompression surgery under local LA. The data collected included demographics, visual analog scale (VAS) scores for leg pain, oswestry disability index (ODI), and modified Macnab grades. The UBE decompression procedure was divided into seven key steps, and intraoperative pain and the effectiveness of LA were assessed using patient self-reported VAS scores at each step. Data comparisons between the preoperative, postoperative, and follow-up time points were conducted using paired sample t-tests.
resultsEighteen patients (5 males and 13 females) with an average age of 77.1 ± 5.0 years were included in the study, with 83.3% (15 patients) having medical comorbidities. The average follow-up period was 14.8 ± 7.9 months. At 3 months postoperative and final follow-up, both VAS scores for leg pain (p < 0.001) and ODI scores (p < 0.001) showed significant improvement. According to the modified Macnab criteria, outcomes were rated as excellent in 13 patients (72.2%), good in one (5.6%), fair in two (11.1%), and poor in one (5.6%), yielding an excellent-good rate of 77.8%. None of the patients voluntarily requested surgery termination because of unbearable intraoperative pain.
conclusionsFor elderly patients with medical comorbidities, UBE decompression under LA is a viable and effective treatment option, yielding favorable clinical outcomes.
