Abstract
Our objectives were to determine the reporting of symptoms, the medical outcome and the work status of meat plant workers diagnosed with clinical carpal tunnel syndrome (CTS). Forty-seven cases of CTS were identified from a previously reported study, and were matched by age, gender and hand use. Cases and controls were followed up for 24 months. The Provincial Workers' Compensation Board and company health records were used to determine the reporting of symptoms, interventions and work status. Thirty-one study cases and all control cases were followed for the full 24 months (16 study cases were lost to follow-up). In total, 12 cases reported symptoms of CTS during the 24 months (eight study cases and four controls). Of the eight study cases, one required surgical release of the carpal tunnel. After a period of work modification, five of the eight study cases returned to regular duty and the remainder were placed on permanent job restrictions. Of the four controls, one subject had a surgical release and returned to regular work, two subjects' jobs were permanently modified, and the fourth returned to regular duty. Occupation-related CTS in meat packers appears to be transient and responsive to conservative measures, with a surgical rate comparable to other occupations.
