Reduced periprosthetic fracture rate for a cemented anatomical versus a tapered polished stem in hip arthroplasty: A 6-year follow-up of a prospective observational cohort study.
Article in Journal of experimental orthopaedics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Purpose: In older patients requiring a hip arthroplasty, the cemented straight collarless polished tapered stems (PTSs) have been linked to an increased risk of periprosthetic femur fractures (PFFs) when compared to anatomically shaped stems (ASs). This study aims to perform a 6-year follow-up of PFF rates and other adverse events of an orthopaedic department's full transition from a cemented PTS to a cemented AS. Methods: A prospective single-centre cohort study included 1077 patients operated with a cemented hip replacement at Danderyd Hospital, Stockholm, Sweden, between 2012 and 2015. Patients were divided into two groups based on stem design: PTS ( Results: Most patients (77.2%, mean age 82 years) underwent surgery for a hip fracture. The 6-year PFF rate was 4.6% for the PTS group and 0.9% for the AS group. PFF patterns differed between groups, with Vancouver B fractures being more common in the PTS group. The AS group had lower rates of PJIs (3.6% vs. 1.7%) and dislocations (4.4% vs. 1.3%) than the PTS group. Conclusion: Transitioning from a PTS to an AS could reduce the PFF rate and other adverse events in hip arthroplasty. The findings are relevant for hospitals treating older and frail patients, as the mean age in this study was >80 years. Further research in different settings is warranted to confirm these results. Level of Evidence: Level II.
