Reducing time from presentation to diagnosis of scaphoid fractures with cone beam CT: a before-and-after study.
Article in Emergency medicine journal : EMJ, 2026. 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
backgroundScaphoid fractures comprise approximately 50-70% of carpal bone fractures but can be difficult to detect on initial plain film radiographs. A delayed diagnosis can lead to a high rate of non-union, avascular necrosis and Complex Regional Pain Syndrome. Current literature supports cone beam CT (CBCT) (within 10-14 days) as an effective method for diagnosing scaphoid fractures. We implemented an early outpatient CBCT pathway, prior to specialist review, with the aim to increase the proportion of patients with suspected scaphoid fracture undergoing CBCT within 7 days.
methodsWe designed an ambulatory pathway for suspected scaphoid fractures in the Emergency Department (ED) in which outpatient CBCT was requested by emergency medicine clinicians. A retrospective audit of current management of these patients was performed between 1 August 2022 and 31 October 2022 (prepathway period). A list of patients who underwent CBCT performed for the indication 'suspected scaphoid or carpal bone fracture' in the hospital was obtained and screened. Implementation of the pathway took place in February 2023 and was reviewed by continuous audit monitoring from 1 March 2023 to 31 May 2023 (postpathway period).
resultsPrepathway implementation, 54 patients underwent CBCT. Following implementation of our pathway, the number of CBCTs performed in the hospital for this clinical indication increased to 111 (postpathway). The proportion of patients undergoing CBCT within 7 days increased from 11.1% (6/54) to 91.8% (102/111) (p<0.000). There was a 71.9% reduction in fracture clinic attendances (50/54 (92.6%) prepathway and 23/111 (22.5%) post pathway (p<0.000).
conclusionWe successfully implemented an ambulatory pathway for suspected scaphoid fractures in the ED that significantly increased the proportion of patients with suspected scaphoid fractures undergoing early (<7 days) CBCT and definitive care.
