Introducing the forearm fracture index to define the diametaphyseal junction zone through clinical evaluation in a cohort of 366 diametaphyseal radius fractures.

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
backgroundUnstable diametaphyseal radius fractures (DMRFs) can be prone to complications, and treatment strategies are heterogeneous. Studies are difficult to interpret as definitions of the diametaphyseal junction zone (DMJZ) are impractical for clinical use, imprecise, or prone to error.
methodsWe introduce the forearm fracture index (FFI) to define DMRFs in radiographs and ultrasound. The FFI is calculated by the ratio of the fracture's distance to the distal radius growth plate over the width of the radius growth plate. The higher the FFI, the more proximal the fracture is. We define DMRFs to have an FFI between 1 and 2. All DMRFs treated at our institution between 2010 and 2020 were identified, and demographic data, fracture characteristics, and therapeutic strategies were assessed retrospectively. Comparative sub-analysis was performed between DMRFs(-) as defined in previous publications (Lieber in Unfallchirurg 114:292-299, 2011) and DMRFs( +) that were more proximal but still met our criteria.
results516 DMRFs were identified, representing 13.0% of all screened radius fractures. Excluding buckle fractures and patients lost to follow-up, 366 DMRFs were eligible for further analysis. Conservatively managed DMRFs were more distal than those managed operatively, represented by a lower FFI (1.28 vs. 1.34, p = 0.0051). 21 (5.7%) of all DMRFs were identified as DMRFs( +). These were significantly more dislocated and necessitated surgery more often than DMRFs(-) (52.4 vs. 24.6%, p = 0.009).
conclusionsThe FFI may be a good tool to identify and describe DMRFs. It can help guiding treatment decisions and make future studies on this entity more comparable. LEVEL OF EVIDENCE: Study of Diagnostic Test, Level II.
