Early versus late construct failure in spine metastatic disease: implications for surgical strategy and oncologic outcome.
Article in Journal of neuro-oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeThis study aimed to identify variables that portend early construct failure requiring surgical revision in patients undergoing instrumented fusion for spine metastases.
methodsA detailed retrospective chart review was performed. Demographic, surgical, and oncologic variables were collected and analyzed via independent samples t-testing, chi-square testing, and Kaplan-Meier method with log-rank testing. Significance was determined as p < 0.05.
results482 spinal fusion operations for solid tumor metastases were performed between 2012 and 2022. Of these, 24 (5.0%) required revision surgery for construct failure. There were no major differences between the revision and non-revision patients in terms of several surgical characteristics. Thirteen (54.1%) were revised within 3 months of index surgery. These early construct failures were more likely to have functional neurological deficits at surgery (6/13 vs. 0/11 [p = 0.009]), longer constructs (mean 6.4±2.4 vs. 4.2 ± 1.4 levels [p = 0.015]), and cement-augmented pedicle screws (4/13 vs. 0/11 [p = 0.044)) compared to late construct failures (> 3 months after index surgery). Additionally, 17 symptomatic failures were identified, compared to 7 asymptomatic failures which were identified incidentally with routine follow-up imaging. All 7 asymptomatic construct failures occurred in the early revisions group [p = 0.004]. Revision surgery for early construct failure was associated with significantly reduced median overall survival compared to late failure (p = 0.010).
conclusionConstruct failures in our cohort were not associated with any classical characteristics of patients undergoing revision spine surgery. Early revision (< 3 months) portends a reduction in overall survival when compared with late revisions, and early revised patients were more likely to have had more extensive surgery and poorer neurological status at the time of index cases.
