Scaphoid fractures: has magnetic resonance imaging become a cost-effective alternative to definitive diagnosis?
Article in Irish journal of medical science, 2020. 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
backgroundA clinical examination finding of anatomical snuffbox tenderness (AST) with plain film radiographs alone yields low sensitivity and specificity in diagnosing scaphoid fractures. International guidelines suggest immediate referral for magnetic resonance imaging (MRI) following one non-diagnostic radiograph in such patients. Perceived cost, high demand and limited capacity of MRI scanners have resulted in few suspected fractures following this pathway in our institution.
aimsOur study aimed to audit cost-effectiveness of immediate MRI referral following one non-diagnostic radiograph in the patient with AST versus current local practice.
methodsRetrospective analysis of all patients with suspected scaphoid fractures referred from the ED to the orthopaedic service over a six-month period was performed. Mean pricing per radiograph, casting, MRI and fracture clinic presentation was obtained from our hospital's Finance department.
resultsNinety-seven patients were identified; 26 had scaphoid fractures (26.8%). Seventy-one patients with no fractures cost a mean €82,111.50 (IQR: €55,025, €98,335) having a mean of 3.1 clinic visits, 4.6 radiographs and 4.7 weeks casted, versus €40,115 for early MRI referral as per guidelines (p > 0.05).
conclusionsIn conclusion, when compared with current local practice, immediate referral of the patient with AST for MRI following one non-diagnostic ED radiograph is potentially cost-effective in establishing efficient diagnosis of scaphoid fractures. We recommend the implementation of published international guidelines in the investigation of query scaphoid fractures as a pragmatic and cost-effective practice.
