E-scooter-related imaging: a new emerging high-energy trauma patient.

objectivesTo quantify the volume and nature of radiological imaging performed for e-scooter related trauma presentations in a tertiary referral centre and to identify common radiological pattern of injuries.

methodsOur study received institutional review board approval. We retrospectively reviewed all anonymised radiological imaging studies performed in our institution for the term 'scooter' or 'e-scooter' between July 2020 and July 2021. The patient demographics, number of imaging studies performed and modality type as well as the nature of injuries identified were recorded.

resultsWithin the study period, 147 patients with e-scooter-related injuries were referred for radiological imaging. Forty-two (29%) of those patients had positive radiological findings. The vast majority of injuries on radiographs were upper limb injuries typical of a fall on outstretched hand (FOOSH) pattern. Thirty-two patients (22%) required advanced diagnostics with CT or MRI with 11 of these patients having positive findings. Four patients suffered significant head injuries including skull fractures and/or intracranial haemorrhage. Five patients suffered facial bone fractures, and 2 suffered spinal fractures. One patient suffered a handlebar abdominal trauma with a resulting large bowel injury ultimately requiring bowel resection.

conclusionE-scooter-related injuries represent a new and emerging high-energy trauma patient. These patients demonstrate injury patterns similar to other high-energy trauma such as road traffic accidents. Although the most common injuries are musculoskeletal upper limb injuries typical of FOOSH, a large proportion of these require advanced diagnostic imaging (CT, MRI) which were commonly positive for significant injuries.
