Morphological typing of anterior process of the calcaneus from lateral X-ray film.

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 investigate the clinical impact of the proposed morphological typing of the anterior process of the calcaneus using frontal and lateral radiographs.
methodsWe consecutively included lateral radiographs of the foot bones of 294 patients with normal ankle joint development from 1 January 2018 to 30 April 2024 at our general hospital for use in this retrospective observational cross-sectional study. The geometric parameters of Bohler Angle and Gissane Angle were measured according to morphological classification, and the length, height, and angle of the anterior process of the calcaneus were measured.
resultsThe anterior process of the calcaneus was classified into 3 types, nasal (145 cases), angular (74 cases), and square (75 cases). In terms of morphological features, the nasal type had a statistically significant (p < 0.05) difference in the angle and length of the anterior process of the calcaneus compared to the angular type, and these parameters were greater than those in the square type. Meanwhile, between square, angular and nasal, there was a statistically significant difference in the height of the calcaneus' anterior process. Furthermore, it was shown that the left and right sides showed no significant differences in any morphological characteristics of the calcaneus except length. Additionally male patients tended to have a higher anterior process height than female patients.
conclusionsBifurcate ligament damage and morphological type may be linked to variations in the calcaneus' anterior process, and the classification may also be useful in making treatment decisions for fractures of this structure. LEVEL OF EVIDENCE: IV.
