This is a 5-year retrospective review of hand injuries caused by exercise bicycles among 34 children.
Mean age was 3 years and 5 months. Accidents were caused most commonly by impingement of the fingers between the chain and sprocket wheel (77%), but injuries caused by spinning wheel spokes (23%) were generally more severe. Injuries were usually of the avulsion type and ranged in severity from lacerations (43%) to fractures (19%) to amputations (38%). The central digits (87%) were involved more frequently than the border digits (13%). Replantation was possible for 33% of the amputated digits, with 50% of the fingers surviving.
The avulsive nature of these injuries should be taken into consideration when attempting replantation. Increased community awareness and equipment safety modifications are needed to eliminate this preventable problem.
这是一项对34名儿童因健身自行车导致手部受伤的5年回顾性研究。
平均年龄为3岁5个月。事故最常见的原因是手指卡在链条和链轮之间（77%），但由旋转的轮辐导致的损伤（23%）通常更严重。损伤通常为撕脱伤，严重程度从撕裂伤（43%）到骨折（19%）再到截肢（38%）不等。中间手指（87%）比边缘手指（13%）更常受累。33%的截肢手指可行再植，其中50%的手指存活。
在尝试再植时应考虑这些损伤的撕脱性质。需要提高社区意识并对设备进行安全改进，以消除这个可预防的问题。
