Neurosurgical Consequences of e-Scooter Use: Strategies to Prevent Neurological Injury

A comprehensive review of current trends in e-scooter associated injuries, associated outcomes, and effective interventions: Towards establishing sustainable prevention interventions

INTRODUCTION

This review aims to provide a comprehensive overview of electric-scooter (E-Scooter) injuries by evaluating the incidence, common mechanisms of injury, clinical outcomes, associated costs, and effective interventions for injury prevention.

METHODS

A literature search using PubMed, Google Scholar, EMBASE, and ProQuest was performed to identify relevant articles published between July 10, 2014, and July 10, 2024. Outcomes of interest included epidemiologic trends of E-Scooter injuries, common mechanisms of injury, associated risk factors, clinical outcomes, and interventions to decrease E-Scooter injuries.

RESULTS

A total of 41 articles were included in this study, with 39 evaluating the epidemiologic trends of e-scooter injuries, 22 the most common mechanisms of injury, 21 assessed intoxication, 15 assessed helmet usage, 33 determined patient's clinical outcomes, and 3 assessed effective interventions for decreasing the incidence of e-scooter injuries. Falls were the most common mechanism of injury; however, collisions with motor vehicles caused more severe injuries. Additionally, studies showed that up to 74 % of all E-Scooter injuries included alcohol intoxication, and over 80 % did not use a helmet leading to severe head injuries.

CONCLUSION

The incidence of E-Scooter related injuries rose significantly in recent years. These injuries typically result from falls and MVAs and are compounded by factors including limited helmet usage and riding while intoxicated. These contribute to the poorer clinical outcomes seen with E-Scooter injuries. However, there remains a significant paucity of literature focused on the outcomes of policies and interventions designed to reduce these injuries. Further investigation must address these gaps and discrepancies to inform future policies.

Electric Scooter Falls: The 2023-2024 Experience in the Clinical Emergency Children's Hospital in Galați

(1) Introduction: Since electric scooters were launched in 2017, they have become increasingly popular worldwide and a cause of childhood trauma. (2) Case reports: This paper has a double-fold purpose: it reports two cases of epidural hematomas and compares them with electric scooter-related head trauma in the literature. An overview of the literature on this topic was performed to make such a comparison. Our cases are one of almost 52 cm3 and one of 129 cm3, both in two eight-year-olds. (3) Discussion: Although usually mild, traumatic brain injuries following e-scooter falls can also be moderate and severe. Reduced helmet use, high speed, and a lack of experience are the perfect set-up for potential severe injuries. Intracranial bleeds are not frequent, and epidural hematomas are rare in such cases, but they can significantly impact the individual, community, and healthcare system. No other medium- or large-sized epidural hematomas were reported in children sustaining electric scooter-related head trauma. (4) Conclusions: Our review parallels the literature and our hospital's experience. Although there are both similarities and discrepancies between our cases and the literature, mild trauma should not be disregarded, for it may hide serious complications requiring immediate surgery.

Characteristics and Injury Patterns in Traumatic Brain Injury Related to E-Scooter Use in Riga, Latvia: Multicenter Case Series

Background and Objectives: In recent years, electronic scooters (e-scooters) have gained popularity, whether for private use or as a publicly available transportation method. With the introduction of these vehicles, reports of e-scooter-related accidents have surged, sparking public debate and concern. The aim of this study was to analyze the epidemiological data, characteristics, and severity of traumatic brain injury (TBI) related to e-scooter accidents. Materials and Methods: This retrospective case series evaluated patients who were admitted to the three largest neurosurgery clinics in Riga, Latvia, from the time period of April to October in two separate years-2022 and 2023-after e-scooter-related accidents. The data were collected on patient demographics, the time of the accident, alcohol consumption, helmet use, the type of TBI, other related injuries, and the treatment and assessment at discharge. Results: A total of 28 patients were admitted with TBI related to e-scooter use, with a median age of 30 years (Q1-Q3, 20.25-37.25), four individuals under the age of 18, and the majority (64%) being male. In 23 cases, the injury mechanism was falling, in 5 cases, collision. None were wearing a helmet at the time of the injury. Alcohol intoxication was evident in over half of the patients (51.5%), with severe intoxication (>1.2 g/L) in 75% of cases among them. Neurological symptoms upon admission were noted in 50% of cases. All patients had intracranial trauma: 50% had brain contusions, 43% traumatic subdural hematoma, and almost 30% epidural hematoma. Craniofacial fractures were evident in 71% of cases, and there were fractures in other parts of body in three patients. Six patients required emergency neurosurgical intervention. Neurological complications were noted in two patients; one patient died. Conclusions: e-scooter-related accidents result in a significant number of brain and other associated injuries, with notable frequency linked to alcohol influence and a lack of helmet use. Prevention campaigns to raise the awareness of potential risks and the implementation of more strict regulations should be conducted.

A retrospective comparative study of maxillofacial injury patterns caused by electric scooters and bicycles

BACKGROUND/AIM

The emergence of shared stand-up electric scooters has led to an increase in their usage and, subsequently, an increase in the incidence of maxillofacial trauma. This study aimed to investigate the trauma pattern associated with the use of stand-up electric scooters compared with that related to the use of bicycles, which was a popular mode of personal mobility before the emergence of stand-up electric scooters.

MATERIALS AND METHODS

This study investigated the medical records of patients who visited Wonju Christian Hospital for maxillofacial trauma due to the use of stand-up electric scooter and bicycles between November 1, 2017 and October 31, 2022. Maxillofacial trauma was analyzed based on medical records, including those in the evaluation results of teeth, maxillofacial bones, and soft tissues.

RESULTS

Crown fractures and tooth avulsions were observed more frequently with the use of stand-up electric scooters than with the use of bicycles. In contrast, crown-root fractures, tooth subluxation, and extrusive luxation were more commonly observed in bicycle riders. Additionally, the proportion of root fractures was similar between the two groups. However, no vertical root fractures were observed in patients who rode bicycles. The maxillofacial bone fracture rates between the two groups were similar, although the fracture patterns were different.

CONCLUSION

The number of patients using stand-up electric scooters is increasing, and they are likely to have a worse prognosis compared with those using existing personal mobility devices.
