A prospective study of angle grinder injuries in the hands and forearms during a one-year period

Abstract

Angle grinders are powerful tools used for cutting, shaving and polishing metal, stone, concrete and many hard surfaces in the work and hobby context. The aim of this study was to evaluate the acute hand injuries caused by angle grinders and to identify risk factors. Out of 742 acute hand and forearm injuries presenting in our emergency department between March 2016 and March 2017, 82 cases of injury due to angle grinder were included in the study. The age, gender, occupation, experience and education level of the injured patients were recorded. In addition, the location, mechanism, time of day, cigarette or alcohol use and occupational cases were determined. The Modified Hand Injury Severity Score (MHISS) was used to determine the injury severity. The vast majority of injuries (except 8) were not occupational injuries. They often occurred when individuals were using this tool outside of a work context (home, etc.); 44% of the patients were retired. There were more injuries between the hours of 3 pm and 6 pm. The mean overall MHISS score of was 74 (2–330). These angle grinder injuries, many of which are severe, are difficult to treat and the resulting disability is high. Many factors, such as smoking, age and time of day contribute to these injuries. Precautions should be taken and safety training should be provided for this powerful tool which is widely used and easy to obtain.
