Analysis of the Ability of a Distal Tibial Anatomical Locking Plate to Capture the Distal Tibial Fragments in Patients with Pilon Fractures.
Article in Orthopaedic surgery, 2023. 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
objectiveAlthough pilon fractures are rare in clinical practice, they are difficult to treat because of their complexity. Effective fixation of the fracture fragment is the key to the treatment of pilon fractures. Plate osteosynthesis is common clinically, but there are many types of plates and the evaluation of the effect of fixation plates is not comprehensive. This study attempted to compare the capture effect of different fixation plates on the fracture fragments based on 3D modeling and fine distinctions of fracture fragments.
methodsThe computed tomography (CT) images before treatment of 127 patients with pilon fractures from January 2019 to December 2021 were retrospectively collected. The fracture lines were mapped and digitally displayed as 3D images using MIMICS 21 software. APLUS distal tibia anatomical locking plate (Plate A) and ZIMMER distal tibia anatomical plate (Plate B) were placed on a pseudo-bone model and CT scans were used to determine the number of screws in the major and minor fragments of pilon fractures. The frequency of the two plates capturing the fracture fragments was recorded.
resultsUnder Assumption 1 or 2, Plate A performed significantly better than Plate B in capturing the major, Chaput, Volkmann, medial malleolus, and die-punch fracture fragments. Plate A captured markedly more minor fragments than Plate B under Assumption 2 but was not significantly different from Plate B under Assumption 1. Plate A or Plate B showed no obvious difference between major and minor capture rates under the same assumption, and A1 or B1 showed a markedly higher capture rate compared with A2 or B2. In addition, there was a significant positive correlation between the major capture rate and the major fragments in B1, and a significant negative correlation between the minor capture rate and the minor fragments in Plates A and B. However, there was no correlation between the major capture rate of Plate A and the major fragments.
conclusionThe APLUS distal tibial anatomical locking plate is superior to the ZIMMER distal tibia anatomical plate in the ability to capture distal tibial fragments in pilon fracture cases.
