Perioperative Selective Serotonin Reuptake Inhibitor (SSRI) Use and Postoperative Fracture Fixation Outcomes: A Multi-institutional Retrospective Cohort Study.
Article in Cureus, 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
introductionSelective serotonin reuptake inhibitors (SSRIs) have been implicated in impaired bone metabolism and delayed fracture healing. This study evaluates the association between perioperative SSRI use and complications following open reduction and internal fixation (ORIF) and intramedullary nailing (IMN) of various long bone shaft fractures. The study hypothesis is that perioperative SSRI use negatively affects fracture healing and increases adverse postoperative outcomes across fixation constructs.
methodsThe TriNetX database was used to identify patients (≥18 years) undergoing humeral, clavicular, or ulna shaft ORIF and humeral, femoral, or tibial shaft IMN. Patients were stratified by SSRI use within one month of the index surgery; controls had no documented SSRI history. Propensity score matching controlled for demographics and relevant comorbidities. Outcomes were assessed at one-year after surgery. Measures of association, including risk ratios (RRs), 95% confidence intervals (CIs), and p-values, were used to compare outcomes between cohorts.
resultsIn the humeral shaft ORIF cohort (n=1,576), SSRI exposure was associated with significantly higher rates of nonunion (RR=1.51, 95% CI: 1.14-2.01; p=0.004) and infection-related implant failure (RR=2.03, 95% CI: 1.31-3.16; p=0.001). In the ulna shaft ORIF cohort (n=567), SSRI use was associated with increased infection-related implant failure (RR=1.94, 95% CI: 1.12-3.39; p=0.017) and mechanical implant failure (RR=1.91, 95% CI: 1.14-3.19; p=0.012). No significant associations were identified in the clavicle shaft ORIF cohort or in any IMN cohort (p>0.05).
conclusionThe study hypothesis was not upheld. While significant adverse associations were observed in select ORIF cohorts, there were no significant differences in adverse outcomes in IMN cohorts. This discrepancy limits the ability to draw an association between SSRI use and impaired fracture healing. Given the higher baseline nonunion rates associated with IMN, the observed differences between cohorts appear inconsistent and likely reflect confounding rather than a true effect of SSRI use.
