Comparing the exposure of the ulna coronoid using the anterior or medial surgical approaches: a cadaveric study.

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: Surgical fixation of isolated coronoid process fractures while maintaining the soft tissue integrity of the elbow joint is challenging. Several surgical approaches are described, each with their own benefits and risks. The purpose of this cadaveric study was to compare the extent of visualization and access to the coronoid process using the medial flexor carpi ulnaris (FCU)-split and anterior brachial artery and median nerve (B-M) approaches. Methods: A total of 33 fresh frozen cadaveric upper limb specimens from 17 cadavers were dissected. Two surgical exposures, a FCU-split and anterior B-M interval approach, were performed on each specimen in a randomized order. The visibility of anatomical landmarks of the coronoid process was documented. Deidentified clinical images of the exposed coronoid were taken and the total surface area exposed was analyzed using SketchAndCalc Area calculator Software. The Medartis Aptus coronoid plate was used to assess the ease of screw hole access via each approach. Results: The anterior B-M approach visualized a significantly greater surface area of the coronoid process compared to the medial FCU-split (35.4 mm Conclusion: The anterior B-M approach provides significantly greater surface area exposure of the coronoid process compared to the medial FCU-split. While the anterior approach excels in visualization of the coronoid tip, the medial approach may provide easier access to multiple screw placement options.
