Anterior vertebrectomy and O-arm navigation for old L5 traumatic fractures with kyphotic deformity: a retrospective case series of clinical and radiological outcomes.
Article in Frontiers in 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
Background: Old L5 traumatic fractures with kyphotic deformity are quite rare and surgical management constitutes a significant challenge. Anterior vertebrectomy and reconstruction with O-arm navigation for old L5 traumatic fractures with kyphotic deformity aim to restore spinal stability, correct deformity, and improve functionality. This study evaluates the efficacy and safety of this approach. Methods: A retrospective case series was conducted on 43 patients with old L5 traumatic fractures and kyphotic deformity who underwent anterior vertebrectomy and reconstruction using O-arm navigation. Data were collected on operation duration, blood loss, radiological and clinical outcomes (VAS, ODI, ASIA, local Cobb angle, and vertebral anterior margin height ratio), Bridwell classification, and complications. Results: The mean operation duration was 182.5 ± 32.8 min, with an average blood loss of 570.5 ± 71.4 mL. All patients had regular follow up with an average duration of 27.1 ± 6.8 months. The VAS scores and ODI at 3 months postoperatively and at the final follow-up showed significant improvement compared to preoperative scores ( Conclusion: Anterior vertebrectomy and reconstruction using O-arm navigation is an effective and safe approach for treating old L5 traumatic fractures with kyphotic deformity in the medium term follow-up. It offers significant pain relief, functional recovery, and sustained correction of spinal alignment, with low complication rates and high fusion success.
