Complications of vertebral augmentation in metastatic spinal fractures: a systematic review of multiple study designs.
Review in Journal of bone oncology, 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: Vertebral augmentation techniques, including vertebroplasty and kyphoplasty, are widely used to relieve pain and restore spinal stability in patients with metastatic vertebral lesions. Despite their widespread use, the full spectrum and clinical significance of procedure-related complications remain incompletely characterised. This systematic review aims to summarise and characterise all reported complications associated with vertebral augmentation for metastatic thoracolumbar disease. Methods: A comprehensive search of PubMed/MEDLINE, Scopus, and Web of Science databases was performed. Studies reporting complications associated with vertebral augmentation procedures for metastatic thoracolumbar spinal fractures were included. Randomised controlled trials, observational studies, case series, and case reports were eligible. Due to substantial heterogeneity across studies, a descriptive synthesis was performed. Results: A total of 76 studies were included, comprising 3234 patients and at least 5737 vertebral levels treated. The overall weighted complication rate was 25.5%, while the weighted rate of symptomatic complications was 3.41%. Cement leakage was the most frequently reported complication, with a weighted mean incidence of 20.7%, although the majority were asymptomatic. Other complications included postprocedural pain (1.77%), pulmonary cement embolism (1.08%), and adjacent level fractures (0.79%). Studies using CT imaging reported significantly higher cement leakage rates (28.6% vs 11.9%, Conclusions: This review presents a comprehensive and detailed description of all complications of vertebral augmentation for treatment of metastatic spine disease and reinforce its safety. Differences in imaging protocols and reporting standards contribute to variability in reported complication rates. Further prospective studies with standardised complication reporting are needed.
