Distal Positioning of the Ulnar Shortening Plate Increases Symptomatic Removal: A Comparative Analysis of Ulnar Shortening Osteotomy Plate Positioning and Symptomatic Hardware Removal.

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: Ulnar shortening osteotomy (USO) is a common procedure to treat symptomatic ulnar-sided wrist symptoms in patients with positive ulnar variance who fail nonoperative management. Plate placement on the volar, dorsal, or subcutaneous border of the ulna has been described. There remains debate regarding the optimal plate placement to minimize soft tissue irritation and the need for plate removal. The goal of this study is to determine whether plate position along the volar cortex versus along the subcutaneous border, as well as the distance of the plate from the ulnar styloid, affects the risk of symptomatic hardware requiring removal. Materials and Methods: In total, 112 USO procedures on 107 patients performed between 2017 and 2023 were retrospectively reviewed. The position of the plate on the ulna and the distance of the plate from the ulnar styloid were assessed radiographically. Demographic information, visual analog scale pain scores, disability of the arm, shoulder, and hand scores, and incidence of hardware removal were collected and compared between plate location groups. Results: The overall symptomatic hardware removal rate was 79%. There was no difference in the rate of symptomatic hardware removal between volar (80%) and subcutaneous (77%) plate locations ( Conclusion: We found no difference in hardware removal rates based on volar versus subcutaneous plate placement after USO. Cases in which hardware was not removed had a higher mean distance from the distal plate to the ulnar styloid. Further prospective studies are warranted to determine optimal plate positioning to minimize hardware irritation after USO.
