Their recent popularity has also resulted in an increase in PMD-related injuries. We aimed to characterise and compare the nature of injuries sustained by PMD users and bicycle riders.<\/jats:p>\n <\/jats:sec>\n \n Methods:<\/jats:title>\n This retrospective study compared injury patterns among PMD and bicycle users. 140 patients were admitted between November 2013 and September 2018. Parameters studied included patients\u2019 demographics (e.g. age, gender and body mass index), type of PMD, nature of injury, surgical intervention required, duration of hospitalisation and time off work.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n Of 140 patients, 46 (32.9%) patients required treatment at the department of orthopaedic surgery. 19 patients were PMD users while 27 were bicycle riders. 16 (84.2%) patients with PMD-related injuries were men. PMD users were significantly younger (mean age 45 \u00b1 15 years) when compared to bicycle riders (mean age 56 \u00b1 17 years;\n P<\/jats:italic>\n <0.05). A quarter (\n n<\/jats:italic>\n = 5, 26.3%) of PMD users sustained open fractures and over half (\n n<\/jats:italic>\n = 10, 52.6%) required surgical intervention. Among 27 bicycle users, 7.4% (\n n<\/jats:italic>\n = 2) of patients sustained open fractures and 70.4% (\n n<\/jats:italic>\n = 19) required surgical intervention. Both groups had comparable inpatient stay duration and time off work.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n PMD-related orthopaedic traumas are high-energy injuries, with higher rates of open fractures, when compared to bicycle injuries. In addition, PMD users are significantly younger and of economically viable age. Prolonged hospitalisation and time off work have socioeconomic implications. Caution should be exercised when using PMDs.<\/jats:p>\n <\/jats:sec>","DOI":"10.11622\/smedj.2021050","type":"journal-article","created":{"date-parts":[[2021,5,18]],"date-time":"2021-05-18T23:55:00Z","timestamp":1621382100000},"page":"445-449","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":4,"title":["Patterns of orthopaedic injury among hospitalised personal mobility device users and bicycle riders: a comparative study"],"prefix":"10.4103","volume":"63","author":[{"given":"Don Thong Siang","family":"Koh","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Singapore General Hospital, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yew Lok","family":"Woo","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Singapore General Hospital, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ting Hway","family":"Wong","sequence":"additional","affiliation":[{"name":"General and Trauma Surgery, Singapore General Hospital, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mann Hong","family":"Tan","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Singapore General Hospital, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2022,9,30]]},"reference":[{"key":"R2-20260528","doi-asserted-by":"crossref","first-page":"102","DOI":"10.1016\/j.aap.2015.10.022","article-title":"Are electric self-balancing scooters safe in vehicle crash accidents?","volume":"87","author":"Xu","year":"2016","journal-title":"Accid Anal Prev"},{"key":"R3-20260528","doi-asserted-by":"crossref","first-page":"424","DOI":"10.1080\/15389588.2014.952724","article-title":"Comparative analysis of risky behaviors of electric bicycles at signalized intersections","volume":"16","author":"Bai","year":"2015","journal-title":"Traffic Inj Prev"},{"key":"R4-20260528","doi-asserted-by":"crossref","first-page":"301","DOI":"10.1007\/s11116-007-9118-8","article-title":"The transition to electric bikes in China:History and key reasons for rapid growth","volume":"34","author":"Weinert","year":"2007","journal-title":"Transportation"},{"key":"R5-20260528","doi-asserted-by":"crossref","first-page":"47","DOI":"10.1016\/j.aap.2014.07.020","article-title":"Evaluation of e-bike accidents in Switzerland","volume":"73","author":"Weber","year":"2014","journal-title":"Accid Anal Prev"},{"key":"R6-20260528","doi-asserted-by":"crossref","first-page":"2140","DOI":"10.1016\/j.injury.2017.08.020","article-title":"Orthopaedic injuries among electric bicycle users","volume":"48","author":"Tenenbaum","year":"2017","journal-title":"Injury"},{"key":"R9-20260528","doi-asserted-by":"crossref","first-page":"437","DOI":"10.1007\/s00247-016-3766-9","article-title":"Hoverboards:Spectrum of injury and association with an uncommon fracture","volume":"47","author":"Schapiro","year":"2017","journal-title":"Pediatr Radiol"},{"key":"R10-20260528","doi-asserted-by":"crossref","first-page":"318","DOI":"10.1080\/15389588.2016.1246723","article-title":"The casualties from electric bike and motorized scooter road accidents","volume":"18","author":"Siman-Tov","year":"2017","journal-title":"Traffic Inj Prev"},{"key":"R11-20260528","doi-asserted-by":"crossref","first-page":"377","DOI":"10.4103\/0019-5413.43373","article-title":"Treatment principles in the management of open fractures","volume":"42","author":"Cross","year":"2008","journal-title":"Indian J Orthop"},{"key":"R12-20260528","doi-asserted-by":"crossref","first-page":"891","DOI":"10.1016\/j.injury.2011.12.007","article-title":"The epidemiology of open fractures in adults.
