Saws are a common source of upper extremity injury. There have been several commercial and government-mandated safety mechanisms designed to reduce the number of saw injuries. We aim to assess the trends in the incidence and impact of saw-related upper extremity injuries over the last 2 decades.
The National Electronic Injury Surveillance System database was queried from January 2003 to December 2022 for upper extremity injuries caused by saws. Summary statistics for primary body part injured and diagnosis were calculated. Linear regression was performed to evaluate trends in the number of injuries over time.
An estimated 1.38 million injuries (weighted) presenting to emergency departments were reported from January 2003 to December 2022. Patients had a mean age of 50.5 ± 18.1. Digits (82.2%) accounted for most injuries, followed by hands (11.9%). The lower arm (3.4%), wrist (1.66%), shoulder (0.3%), elbow (0.2%), and upper arm (0.2%) accounted for fewer injuries. There was a downtrend in number of saw injuries over the study period (R = 0.83, R2 = 0.69, < .001). Subgroup analysis showed decreases in number of injuries to fingers (R = -0.82, R2 = 0.67, < .001) and wrists (R = -0.61, R2 = 0.37, = .004). The most common diagnoses were lacerations (69.7%), fractures (12.6%), and amputations (9.9%).
Upper extremity saw injuries have significantly decreased over the last 20 years. The fingers and hands account for the vast majority of saw injuries, resulting most commonly in lacerations, fractures, and amputations.

锯子是上肢损伤的常见原因。已经有几种商业和政府强制规定的安全机制来减少锯伤的数量。我们旨在评估过去20年中与锯相关的上肢损伤的发生率和影响趋势。
查询2003年1月至2022年12月的国家电子伤害监测系统数据库中由锯子导致的上肢损伤情况。计算受伤主要身体部位和诊断的汇总统计数据。进行线性回归以评估损伤数量随时间的趋势。
2003年1月至2022年12月期间，估计有138万例（加权）损伤患者到急诊科就诊。患者的平均年龄为50.5±18.1岁。手指（82.2%）受伤占大多数，其次是手部（11.9%）。前臂（3.4%）、手腕（1.66%）、肩部（0.3%）、肘部（0.2%）和上臂（0.2%）受伤较少。在研究期间，锯伤数量呈下降趋势（R = 0.83，R2 = 0.69，P <.001）。亚组分析显示手指（R = -0.82，R2 = 0.67，P <.001）和手腕（R = -0.61，R2 = 0.37，P =.004）的损伤数量减少。最常见的诊断是撕裂伤（69.7%）、骨折（12.6%）和截肢（9.9%）。
在过去20年中，上肢锯伤显著减少。手指和手部占锯伤的绝大多数，最常见的损伤类型是撕裂伤、骨折和截肢。
