Percutaneous screw fixation combined with cement augmentation for sacral insufficiency fractures: bicentric study.
Article in European radiology, 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
objectivesTo evaluate the functional outcomes after percutaneous screw fixation combined with cement augmentation in patients with osteoporotic sacral insufficiency fractures. MATERIALS AND
methodsIn this bicentric retrospective study, elderly patients with sacral insufficiency fractures were treated using percutaneous screw fixation with cement augmentation. Functional mobility was assessed using a 6-point scale at baseline, Day 1, 6 weeks, and 6 months. Secondary outcomes included pain scores, hospital stay, and complications. Functional and pain score evolutions were analyzed using linear mixed-effects models. Subgroup analyses explored interaction effects with fracture characteristics.
resultsSixty-eight patients were included. Functional scores increased from an estimated marginal mean of 2.43 (95% CI, 2.00-2.86) at baseline to 3.51 (3.05-3.97) on Day 1, 4.15 (3.69-4.61) at 6 weeks, and 4.06 (3.31-4.81) at 6 months (all p < 0.001). Pain scores decreased from 6.60 (6.11-7.10) at baseline to 2.48 (1.96-3.01) on Day 1, 1.15 (0.62-1.67) at 6 weeks, and 1.10 (0.27-1.92) at 6 months (all p < 0.001). Same-day discharge was achieved in 43% of patients. Three complications occurred (4.4%): one asymptomatic cement leakage and two grade 3 events, including one delayed hemorrhage and one screw loosening, both of which were managed without lasting effects. Functional gains varied by fracture pattern, with a statistically significant interaction observed in patients with associated obturator ring fractures (interaction p = 0.003).
conclusionPercutaneous screw fixation with cement augmentation provides early and sustained improvement in both function and pain in elderly patients with osteoporotic sacral insufficiency fractures, with a low complication rate and potential for outpatient management. KEY POINTS: Question The clinical effectiveness of percutaneous screw fixation with cement augmentation remains to be further characterized in osteoporotic sacral insufficiency fractures. Findings Functional and pain scores improved significantly from Day 1 to 6 months, with a low complication rate and 43% of patients managed as outpatients. Clinical relevance Facilitating rapid discharge and symptom relief, this strategy aligns with the goals of geriatric care by minimizing hospitalization and promoting early functional recovery.
