The purpose of this study was to identify variables associated with traumatic amputations in the workplace. Case files of work-related amputations in Minnesota during 1977 were accessed in cooperation with the Workers' Compensation Division of Minnesota. Data analysis was conducted by computer using the Statistical Package for Social Sciences.Of the 109 amputation cases, a mean age of 31 years (range 16 to 80) was identified; 50% of all cases were below the age of 25 years. By gender, males accounted for five times as many cases as females. Operatives incurred the largest number of amputations (40%); yet, they account for only 14% of the total work force. Manufacturing accounted for a majority (43.4%) of the traumatic amputations while including only 18 percent of the work force.Prevention strategies employed subsequent to the injuries included: training only (32.1%), engineering controls (10.1%), and mixed strategies (3.0%); further analysis revealed that although application of passive controls to the specific source (eg, machine) of the injury would have been most appropriate, training was frequently the only intervention incorporated. Recommendations, including Haddon's strategies for prevention and control of amputations are presented.
