Three hundred thirty chain saw injury patients arriving at the emergency clinic of a community hospital in the southeast United States between 1972 and 1979 were reviewed. Forty-eight patients were admitted to the hospital with severe injuries requiring extensive repair; another was dead on arrival at the emergency clinic. The retrospective study reveals a typical pattern in chain saw injuries as injuries caused by other power tools have typical patterns: the majority of the injuries occur on the left side. Most injuries are caused by saw kickback, upward or downward; the face (not usually eyes), neck, hands and feet are most frequently injured. The findings suggest that many of these extensive, expensive injuries can be prevented by proper equipment and training, and by operator compliance with safety procedures. An automatic motor brake is now being installed on many saws, and laws are being prepared to make its use mandatory.
对1972年至1979年间抵达美国东南部一家社区医院急诊室的330名链锯伤患者进行了回顾性研究。48名患者因重伤入院，需要进行广泛修复；另有1名患者在抵达急诊室时死亡。这项回顾性研究揭示了链锯伤的典型模式，正如其他电动工具造成的伤害也有典型模式一样：大多数伤害发生在左侧。大多数伤害是由锯片向上或向下的反冲造成的；面部（通常不是眼睛）、颈部、手和脚是最常受伤的部位。研究结果表明，通过适当的设备和培训，以及操作人员遵守安全程序，许多这类严重且昂贵的伤害是可以预防的。现在许多锯子都安装了自动马达刹车装置，并且正在制定法律强制要求使用该装置。
