Arthroscopic-Assisted Uni-Portal Spinal Surgery Combined With Kirschner Wire Anchoring for Cervical Spondylotic Radiculopathy: A Technical Note and Preliminary Clinical Results.
Article in Orthopaedic surgery, 2026. 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
purposePosterior endoscopic surgery has become a mainstream minimally invasive approach for the treatment of cervical spondylotic radiculopathy (CSR). Arthroscopic-assisted uni-portal spine surgery (AUSS), an emerging technique, has demonstrated favorable clinical outcomes in lumbar spine surgery; however, its feasibility and effectiveness in cervical spine surgery have not yet been reported. Accordingly, this technical note aimed to describe the surgical technique of AUSS combined with Kirschner wire anchoring for the treatment of CSR and to evaluate its preliminary clinical outcomes.
methodsFifteen consecutive CSR patients (9 males, 6 females) underwent AUSS combined with Kirschner wire anchoring between February and October 2024. Clinical outcomes were evaluated using the Visual Analogue Scale (VAS) for neck and arm pain, the Neck Disability Index (NDI), and the modified MacNab criteria. Pre- and postoperative pain and functional scores were compared using a paired t-test, with effect sizes (Cohen's d) and 95% confidence intervals (CIs) for mean differences calculated. Radiological parameters included osteotomy area and facet joint resection rate.
resultsAll procedures were successfully completed with a mean operative time of 97.7 ± 18.2 min and a mean incision length of 1.7 ± 0.2 cm. Postoperatively, VAS score for arm improved from 6.5 ± 0.9 to 2.8 ± 0.7 (p < 0.05), VAS score for neck from 4.3 ± 1.9 to 2.7 ± 1.0 (p < 0.05), and NDI from 54.3 ± 6.7 to 9.7 ± 2.4 (p < 0.05). The mean osteotomy area measured 98.6 ± 12.1 mm
conclusionThe AUSS with Kirschner wire anchoring achieved significant pain relief and functional improvement in CSR, demonstrating feasibility and safety in the short term. However, larger cohorts and long-term studies are required to validate its efficacy.
