Bicortical versus unicortical fixation of plated clavicular fractures: A biomechanical study.
Article in Shoulder & elbow, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeTo compare the biomechanical properties of three plate stabilization techniques for midshaft clavicle fractures: anatomical bicortical locking construct, anatomical unicortical locking construct, and reconstruction bicortical locking construct.
methodsWe analyzed superior plating of the clavicle using an anatomical clavicle plate (Acumed) with both bicortical or unicortical screw fixation and a locking reconstruction plate (DePuy-Synthes). Twenty-one fourth generation composite clavicles were used for non-destructive stiffness testing in axial loading, bending, and torsion. Fifteen composite clavicles and 17 foam clavicles were used for cyclic failure testing using a combined loading method that included all three loading modes.
resultsNo significant differences were found between the three constructs in torsional stiffness nor in vertical bending loading. In axial loading, the anatomical bicortical locking construct was significantly stiffer than either anatomical unicortical locking construct or the reconstruction bicortical locking construct. The unicortical fixation was also significantly stiffer than the reconstruction bicortical locking construct. Regarding failure testing, there was not a significant difference between the bicortical and unicortical anatomical locking constructs; however, both were significantly stronger than bicortical screw fixation in the reconstruction plate.
conclusionBased on the biomechanical performance of these constructs, unicortical locked plate fixation may be a reasonable option in the treatment of displaced midshaft clavicle fracture fixation.
