1 · What the graph read from it

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.

2 · The registry

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

introductionSurgical education consists often times of a discrepancy between necessary amount of provided operative teaching and amount of organizational and ward duties. Operative education is often cut to a minimum. As public awareness toward surgical competence raises, so must the educational system. Courses that provide pre-fractured cadaveric specimens can facilitate surgical teaching realistically, prior to operating on living patients. The aim of this study is to introduce a realistic distal radius fracture simulation setup. MATERIALS AND

methods12 cadaveric specimens (3 male, 9 female) were fixed onto a custom drop-test-bench in the hyperextension of the wrist. The forearm was cut midway between elbow and carpus. The distal part of the forearm was potted, and the specimen was exposed to a high energetic impulse. CT imaging was performed after fracture simulation to detect the exact fracture patterns. We used the AO/ASIF recommendations and four-corner concept to classify the achieved fractures by two independent trauma surgeons.

resultsAll cadaveric specimens could be successfully fractured. 11 fractures were classified as type 23C3.2 and one was classified as type 23C3.3, as additional fracture of diaphysis occurred. Subclassification according to the four-corner concept showed all fractures to be type C. A concomitant ulnar styloid fracture was observed in 4 cases. Furthermore, all cases showed at least one fragment involving the sigmoid notch. There was no statistically significant correlation found regarding Hounsfield Units (HU) and age (p value 0.402), as well as HU and required kinetic energy (p value 0.063).

conclusionA high energetic impulse induced by a custom-made drop-test bench can successfully simulate realistic distal radius fractures in cadaveric specimens with intact soft tissue. Furthermore, these pre-fractured specimens can be utilized in surgical education to provide a teaching experience as realistic as possible without harming living patients.
