Right heart dysfunction does not increase mortality associated with cemented hemiarthroplasty for hip fractures: A retrospective, preliminary analysis.
Article in PloS one, 2025. 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
backgroundCemented hemiarthroplasty (CH) is the preferred treatment for geriatric intracapsular hip fracture. Historically, there has been concern regarding cardiopulmonary morbidity related to bone cement impaction syndrome (BCIS). Right ventricular dysfunction predisposes to BCIS, though limited data supports this association. The purpose of this study was to evaluate if right heart dysfunction was predictive of mortality and cardiopulmonary morbidity following cemented hip hemiarthroplasty. METHODS AND
findingsThis study was a retrospective chart review and analysis conducted at a tertiary referral medical center. Patients who underwent hemiarthroplasty (cemented or press fit) at a single institution for the treatment of intracapsular hip fracture between January 1, 2013, and January 1, 2021 and had an echocardiogram completed within 90 days of their surgery were retrospectively included. Two groups of patients with right heart dysfunction were evaluated: 1) patients who carried a preexisting diagnosis of pulmonary hypertension prior to hospital admission for hip hemiarthroplasty and, 2) patients with echocardiographic evidence of pulmonary hypertension. The primary outcomes included intraoperative hemodynamic instability consistent with bone cement impaction syndrome (BCIS), in-hospital mortality, and 1-year mortality. N = 74 patients were included. 45 patients underwent cemented hemiarthroplasty and 29 patients received press-fit stems. Preexisting diagnosis of right heart dysfunction and echocardiographic evidence of right heart dysfunction were not significantly associated with BCIS, in-hospital, nor 1-year mortality. However, cementation was significantly associated with 1-year mortality (p < 0.05).
conclusionsRight heart dysfunction does not appear to predispose patients to cardiopulmonary complications or early mortality following cemented hip hemiarthroplasty. Cementation was, however, independently associated with 1-year post-operative mortality. These data add to a growing body of literature which suggests that patients with multiple medical comorbidities may be at risk of adverse outcomes related to cementation. BCIS is uncommon, remains poorly understood, and further investigation is warranted.
