Workplace injuries are tracked by the U.S. Department of Labor, Bureau of Labor Statistics, with data published annually on these injuries (http://www.bls.gov/news.release/osh2.toc.htm ). Musculoskeletal workplace injuries include fractures, bruises/contusions, and amputations, as well as musculoskeletal disorders (MSDs). MSDs are often cumulative and include repetitive motion injuries that occur when the body reacts to strenuous repetitive motions (ie, bending, climbing, crawling, reaching, twisting) or overexertion. MSD injuries include sprains, strains, tears, back pain, soreness, carpal tunnel syndrome, hernia, and musculoskeletal system and connective diseases. MSD cases are more severe than the average nonfatal workplace injury or illness, typically involving an average of several additional days away from work. In 2011, the median number of days away from work for all workplace injuries was 8 days; for MSD injuries, the median was 11 days. (Reference Table 6B.2.1 PDF CSV)
