Risk factors for mortality in periprosthetic femur fractures about the hip-a retrospective analysis.
Article in International orthopaedics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeFractures around the hip are known to be an indicator for fragility and are associated with high mortality and various complications. A special type of fractures around the hip are periprosthetic femur fractures (PPF) after Total Hip Arthroplasty (THA). The aim of this study was to investigate the mortality rate associated with PPF after THA and to identify risk factors that may increase it.
methodsConsecutive patients (N = 158) who were treated for a PPF after THA in our university hospital between 2010 and 2020 were identified and mortality was assessed using the residential registry. Univariate (Kaplan-Meier-Estimator) and multivariate (Cox-Regression) statistical analysis was performed to identify risk factors influencing mortality.
resultsOne-year-mortality rate was 23.4% and 2-year mortality was 29.2%. Mortality was significantly influenced by age, gender, treatment, type of comorbidity and time of surgery (p < 0.05). Surgical treatment during regular working hours (8 to 18 h) reduced mortality by 53.2% compared to surgery on call (OR: 0.468, 95% CI 0.223, 0.986; p = 0.046). For every year of age, mortality risk increased by 12.9% (OR: 1,129, 95% CI 1.078, 1.182; p < 0.001). The type of fracture according to the Vancouver classification had no influence on mortality (p = 0.179). Plate fixation and conservative treatment were associated with a higher mortality compared to revision arthroplasty (plate: OR 2.8, 95% CI 1.318, 5.998; p = 0.007; conservative: OR 2.5, 95% CI 1.421, 4.507; p = 0.002).
conclusionSurgical treatment during regular working hours is associated with lower mortality compared to surgery outside these hours. In this retrospective cohort, time to surgery showed no significant impact on all-cause mortality, and revision arthroplasty was associated with lower mortality than conservative treatment or plate fixation. LEVEL OF EVIDENCE: IV (Retrospective cohort study).
