Consequences of Periprosthetic Fracture After Hemiarthroplasty of the Hip.
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
Introduction Low-energy femoral neck fracture (FNF) in the elderly is a serious injury. For patients with multiple existing comorbidities and frailty, the risk of complications, poor functional outcomes, and premature death may be higher. The treatment aims for immediate weight-bearing, preferably by hemiarthroplasty (HA). Previous research has focused on prosthetic joint infection and dislocation after HA. In this study, we aimed to describe the possible surgical consequences of periprosthetic fracture after HA. Methods HA patients with a periprosthetic fracture occurring between 2009 and 2019 were included in this retrospective cohort study. Patients were identified using local quality registers and systematic searches of the patient administrative system. Results We identified 56 periprosthetic fractures. A total of nine patients (16%) experienced complications related to the fracture. Of these, 42 patients were treated surgically for the periprosthetic fracture, and four patients required additional surgeries. Three of these four reoperated patients underwent two further operations, while one patient had a single reoperation. Within three months after surgery, three patients had died. Seventeen of the 56 patients (30%) required a permanently higher level of care after the periprosthetic fracture, and we observed an increased risk of new long-term care admissions (odds ratio (OR): 2.1; 95% confidence interval (CI): 1.1-4.2; p = 0.04). The 30-day mortality rate was 7%, and the one-year mortality rate was 27%. Most patients were treated surgically for their periprosthetic fractures. Regardless of treatment, 16% of patients experienced surgically related complications. Among the operated patients, 10% required additional surgical procedures. Nearly one-third of patients ultimately needed a permanently higher level of care following the injury. Conclusions In our cohort, we observed a low number of surgical complications, and only a few patients required reoperations. However, about one-third of the patients ultimately required a higher level of care.
