Stabilizing the Unstable: Cone Hemiarthroplasty in Geriatric Intertrochanteric Fractures.
Article in Arthroplasty today, 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
Background: Unstable intertrochanteric fractures in the elderly pose a significant treatment challenge due to poor bone quality, comminution, and associated comorbidities. Bipolar hemiarthroplasty offers the advantage of early mobilization and reduced fixation-related complications. This study evaluates short-term outcomes of bipolar hemiarthroplasty using an uncemented titanium fluted, tapered cone femoral prosthesis in such fractures. Methods: A retrospective analysis was conducted on 43 consecutive elderly patients treated with uncemented bipolar hemiarthroplasty using a tapered, fluted cone stem between June 2023 and July 2024. Radiographic parameters-including stem subsidence, greater trochanter union, and limb-length discrepancy-were assessed at serial follow-ups. Functional outcomes were evaluated using the Harris Hip Score. Results: Of the 43 patients operated on, 40 completed a minimum of 12 months follow-up. Greater trochanteric union was observed in 97.7% of cases, with one persistent nonunion causing abductor weakness and early dislocation. Mean stem subsidence was 3.5 mm (0.5-20 mm), with all settling occurring within the first 3 postoperative months; 4 patients (9.3%) experienced subsidence of 5 mm or more, including one requiring revision. The mean limb-length discrepancy was 4.7 mm (1-10 mm). At final follow-up, the mean Harris Hip Score among surviving patients was 91.28, with 29 patients (72.5%) achieving excellent outcomes and 11 patients (27.5%) achieving good outcomes. Conclusions: Bipolar hemiarthroplasty using a tapered, fluted cone stem appears to be a reliable option for carefully selected elderly patients with unstable intertrochanteric fractures, offering predictable fixation, early weight-bearing, and favorable short-term functional results.
