A review was conducted of all cumulative trauma disorder (CTD) injuries to the upper extremities for 1985 through 1989 among workers in mines. All injuries in coal mining and metal/nonmetal mining which were reported as irritated tendon injuries and occupational diseases of the upper extremities were selected for analysis. The narrative was analyzed to exclude acute injuries. Injuries were divided into carpal tunnel syndrome and CTD injuries excluding carpal tunnel syndrome. Age, years of work experience, and job title were examined in relation to development of CTD. The results of the analysis indicated that incidence rates in mining were lower than in the private industry sector. The number of reported CTD injuries increased seven fold in that time, and the percentage of all mining injuries which were of this type increased five fold. The increase may be a result of CTDs being increasingly reported. Of all CTD injuries, 80% occurred to workers at metal/nonmetal mines. Coal mines contributed the other 20%. Four specific occupations in this industry accounted for nearly 63% of this type of injury including mechanics, laborers, boney operators, and miners not elsewhere classified.
