The proportion of mobility scooter users in the United States continues to rise. However, these devices impart a substantial yet underappreciated risk of serious injury - namely, fractures - on users.
The purpose of this cross-sectional, retrospective study was to use the National Electronic Injury Surveillance System (NEISS) to quantify the national burden of these device-associated fractures between 2004 and 2017, analyzing in two-year intervals. We also projected estimates to 2025, and described the demographic characteristics of those injured.
We found that national estimates of device-associated fractures increased significantly between the 2004-2005 (N = 2583; C.I. 1851 - 3316) and 2016-2017 (N = 6553; C.I. 5026 - 8081) periods (p < 0.001). A linear regression model (R = 0.89; P = 0.002) was applied to project 9824 such fractures (C.I. 8273-11,328) in the 2024-2025 period. Injured patients were commonly over age 65 (63.5%; C.I. 57.7%-69.4%) and white (61.4%; C.I. 50.7% - 72.1). Fractures often occurred at home (28.6%; C.I. 22.0%-35.3%) or in public (26.0%; C.I. 21.1%-30.9%).
Our study suggests that osteoarthritic patients relying on mobility scooters to manage pain during ambulation should be considered candidates for total joint replacement procedures. This may help minimize the growing economic and health burden of mobility scooter fractures.
在美国，机动踏板车使用者的比例持续上升。然而，这些设备给使用者带来了严重伤害的重大风险，即骨折，而这种风险尚未得到充分认识。
这项横断面回顾性研究的目的是利用国家电子伤害监测系统（NEISS）来量化2004年至2017年间这些与设备相关骨折的全国负担，每两年进行一次分析。我们还预测了到2025年的估计数，并描述了受伤者的人口统计学特征。
我们发现，与设备相关骨折的全国估计数在2004 - 2005年（N = 2583；置信区间1851 - 3316）和2016 - 2017年（N = 6553；置信区间5026 - 8081）期间显著增加（p < 0.001）。应用线性回归模型（R = 0.89；P = 0.002）预测2024 - 2025年期间此类骨折将达9824例（置信区间8273 - 11328）。受伤患者通常年龄在65岁以上（63.5%；置信区间57.7% - 69.4%）且为白人（61.4%；置信区间50.7% - 72.1%）。骨折常发生在家中（占28.6%；置信区间22.0% - 35.3%）或公共场所（占26.0%；置信区间21.1% - 30.9%）。
我们的研究表明，依靠机动踏板车在行走时缓解疼痛的骨关节炎患者应被视为全关节置换手术的候选对象。这可能有助于将机动踏板车骨折日益增加的经济和健康负担降至最低。
