Introducing the Universal Periprosthetic Femur Fracture (UPFF) Classification: All Fractures Femur.
Article in Journal of clinical medicine, 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
Peri-Prosthetic Femur Fractures (PPFFs) are occurring with increasing frequency as the incidence of hip and knee arthroplasty is rising globally. PPFFs are presenting with more complex patterns commensurate with the increasing sophistication of implant technology and surgical technique. Moreover, with patients undergoing arthroplasty procedures at a younger mean age, it is not uncommon to see both ipsilateral implants (hip and knee) being affected by the fracture. Previous classifications have separated PPFFs into the hip or knee regions, and most do not include fracture patterns about revision-style implants. Prior schemes are antiquated and are not applicable to all current fracture patterns. We present a codified anthropometric, rule-based staging system that incorporates PPFFs across the entire femur. This system is designed to standardize communication and capture variables relevant to treatment planning and future research analysis. Formal reliability and clinical validation studies are ongoing.
