Unipolar Hip Hemiarthroplasty in Geriatric Patients: A Prospective Study and Analysis of Clinical and Radiological Outcomes.

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: Femoral neck fractures (FNF) in the geriatric population are commonly treated with hip replacement procedures, such as total hip arthroplasty, unipolar hip hemiarthroplasty (UHA), and bipolar hip hemiarthroplasty (BHA). The optimal treatment remains controversial, considering outcomes and cost-effectiveness, with UHA often being cheaper. This prospective observational study aims to evaluate UHA's clinical and radiological outcomes, safety, and survivorship compared to existing literature. Methods: We followed 90 elderly patients who underwent UHA following FNF. We assessed patients using the Parker score before and after surgery, as well as Harris Hip Score (HHS), and Postel-Merle d'Aubigné (PMA) scores postoperatively. All complications, acetabular erosions and heterotopic ossifications (HO), were documented. Results: One year post-surgery, 26.7% of patients had passed away, mostly due to declining general health status. Systemic complications occurred in 14.4% of cases, with a 1.1% rate of deep surgical site infections. A single dislocation resulted from excessive stem anteversion. UHA implant survival rate was 97.8% after 4 years. The Parker score remained stable, and HHS at 6 and 12 months was 71.5 ± 12.9 and 70.9 ± 11.8, respectively, while PMA score was 14.3 ± 2.4 and 14.5 ± 2.1, respectively. Five hips showed Baker I acetabular wear. HO were noted as Brooker I in 12 patients, II in 4 patients, and IV in 1 patient. Discussion: UHA exhibited comparable systemic complication rates, implant survivorship, and dislocation rates to those in the literature for both UHA and BHA. The deep surgical site infection rate was lower than reported for BHA. Patients' functional and mental abilities did not decline based on clinical scores. Acetabular wear in UHA was similar to its bipolar counterpart, while HO were only minor findings with no clinical implications. Conclusion: In elderly patients, UHA demonstrated clinical and radiological outcomes similar to BHA in existing literature. UHA may represent a cost-effective alternative for patients with limited life expectancy.
