A Fragile Balance: Survival Analysis Following Bipolar Hemiarthroplasty in the Elderly.
Article in Indian journal of orthopaedics, 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
Introduction: Hip fractures in the elderly are a significant cause of morbidity and mortality, with 1-month and 1-year mortality rates reaching up to 10% and 20%, respectively. While non-modifiable risk factors such as age and comorbidities are well-documented, modifiable factors such as surgical delay and rehabilitation remain underexplored in the Indian context. This study aimed to evaluate postoperative mortality and survival outcomes in elderly patients undergoing bipolar hemiarthroplasty and identify key predictors of mortality. Methods: A retrospective cohort study was conducted on patients aged ≥ 70 years who underwent bipolar hemiarthroplasty for proximal femoral fractures at a tertiary institute from January 2021 to July 2024. Data were collected from hospital records and follow-up was conducted telephonically. Patients with incomplete records or who were unavailable for follow-up were excluded. Survival was assessed using Kaplan-Meier analysis, and predictors were evaluated using log-rank tests and Cox proportional hazards modeling. Results: Sixty-two patients (30 males, 32 females) were included; 46 were aged ≥ 75 years. Cemented implants were used in 30 and uncemented in 32 patients. Comorbidities were present in 19 patients. Seventeen patients (27.4%) died during follow-up: 8 within 1 month, 7 within 6 months, and 2 within 2 years postoperatively. The mean time to mobilization was 3.27 days. Increasing age was a significant predictor of mortality (HR 1.08; 95% CI 1.01-1.17; Conclusions: Advanced age and the presence of comorbidities significantly increase the risk of mortality following bipolar hemiarthroplasty in elderly patients. Early postoperative deaths highlight the need for timely surgery and robust perioperative care. Improving systemic optimisation may offer the best chance at enhancing survival in this high-risk population.
