Crosslink augmentation in posterior fixation of unstable thoracic and thoracolumbar fractures: A comparative cohort study of mechanical failure and sagittal alignment.

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: The value of crosslink augmentation in posterior thoracolumbar instrumentation for traumatic fractures remains uncertain. Although biomechanical studies suggest improved rotational stability, clinical evidence is limited. Objective: To compare mechanical failure and sagittal alignment in posterior pedicle-screw constructs with and without crosslink augmentation for traumatic thoracic, thoracolumbar, and lumbar fractures. Methods: A retrospective single-center comparative cohort study included patients treated between January 2018 and March 2026 for traumatic thoracic, thoracolumbar, or lumbar fractures. Patients were grouped according to crosslink use. The primary outcome was construct-related mechanical failure, including rod fracture, screw loosening, implant disconnection, crosslink failure, progressive loss of correction, or revision for deformity. Local kyphosis was measured preoperatively, postoperatively, and at final follow-up. Results: Twenty-eight patients were analyzed: 13 with crosslink augmentation and 15 without crosslinks. Crosslink constructs were longer, with more instrumented levels (4.9 vs. 3.9; Conclusion: Crosslink-augmented constructs showed no mechanical failures despite greater baseline complexity. These findings suggest potential mechanical benefit, but larger studies are required.
