To investigate the relationship between hand dominance and the risk of major hand injury, the case records of 125 patients who had been treated for digital amputation were retrospectively reviewed. A second group of 116 patients treated for minor hand trauma was similarly evaluated. The incidence of left-hand dominance among the digital amputation group was 35%, and among the minor trauma group the incidence was 11%. The left-handed were more likely to have an amputating injury of their dominant hand than were the right-handed (70% compared with 51%, respectively). The most common mechanism of amputating injury was by power saw. The present data suggest that left-handed individuals have a relative risk of sustaining an amputating injury that is 4.9 times greater than the right-handed individuals, while minor hand trauma occurs at rates proportional to the distribution of left handedness within the population. Additional safety measures and the redesigning of tools, assembly lines, and workstations are recommended to help decrease the incidence of serious hand injury among left-handed individuals.
为了研究用手习惯与严重手部损伤风险之间的关系，我们回顾性分析了125例因手指截肢接受治疗的患者的病例记录。另外对116例因轻度手部创伤接受治疗的患者进行了类似评估。手指截肢组中左利手的发生率为35%，轻度创伤组中这一发生率为11%。与右利手者相比，左利手者更有可能在其优势手发生截肢损伤（分别为70%和51%）。截肢损伤最常见的机制是电锯伤。目前的数据表明，左利手个体遭受截肢损伤的相对风险比右利手个体高4.9倍，而轻度手部创伤的发生率与人群中左利手的分布比例成正比。建议采取额外的安全措施，并重新设计工具、装配线和工作站，以帮助降低左利手个体严重手部损伤的发生率。
