The clinical presentation and management of 19 children who sustained injuries by stationary exercise bicycles were reviewed retrospectively. These injuries represented 32 traumatized digits with a minimum of 2-year follow-up. The index and long fingers were most commonly involved. Wheel-spoke injuries typically produced repairable nerve and tendon lacerations, and full functional recovery in these cases was common. The chain/sprocket injury involved a crushing mechanism and frequently produced severe injury including amputations that were not salvageable. Stationary exercise bicycles represented a predictable source of severe hand injury in children between the ages of 18 months and 5 years. Adult supervision was not reliable in preventing contact between an operating exercycle and a child's hand. We recommend that children not be allowed access to any stationary exercycle machinery, whether it is in use or not. Safety design considerations should focus on not only shielding the wheel spokes, but also (and perhaps even more important) on enclosing the entire chain axis and gear interface. In addition to these design considerations, public education will be critical in reducing the incidence of injury.
回顾性分析了19名因固定健身自行车受伤儿童的临床表现及治疗情况。这些损伤涉及32个受伤手指，随访时间至少为2年。示指和中指最常受累。轮辐损伤通常导致可修复的神经和肌腱撕裂伤，这些病例中功能通常能完全恢复。链条/链轮损伤涉及挤压机制，常导致严重损伤，包括无法挽救的截肢。固定健身自行车是18个月至5岁儿童严重手部损伤的一个可预测来源。成人监督在防止运转中的健身自行车与儿童手部接触方面并不可靠。我们建议不允许儿童接触任何固定健身自行车设备，无论其是否在使用。安全设计考虑不仅应侧重于遮挡轮辐，而且（可能甚至更重要的是）应封闭整个链条轴和齿轮接口。除了这些设计考虑外，公众教育对于减少损伤发生率至关重要。
