Electric scooter-related orthopaedic injuries in Wellington.

Aim: Commercially operated electric scooters (e-scooters) were introduced to Wellington City in June 2019. This study aims to compare e-scooter-related orthopaedic injuries presenting to Wellington Hospital from June 2017 to June 2021, with data from other regions of New Zealand.

Methods: The Wellington Hospital Accident Compensation Corporation Department provided a list of e-scooter-related claims presenting to Wellington Hospital over the 48-month period. A retrospective review was performed. Data were collected for patient demographics, circumstances of injury, management and follow-up. A single investigator reviewed all relevant imaging.

Results: Between June 2017 and 2019, there were 14 e-scooter-related presentations with a total of two orthopaedic fractures in a single patient. Over the 2 years following June 2019, there were 295 e-scooter-related presentations. One hundred and seventeen patients sustained a total of 145 orthopaedic fractures. Twenty-nine percent of orthopaedic fractures required operative management. Intoxicated riders had a higher rate of open long bone fractures (p=0.003).

Conclusion: Orthopaedic injuries are common with e-scooter use. Higher rates of orthopaedic fractures in Wellington City require operative management compared with Auckland. The establishment of regulations and education around use of personal protective equipment, use while intoxicated and speed limits would also be beneficial.
