A systematic review of arthrosis of finger joints in relation to occupational exposure revealed 11 epidemiological studies and 13 case reports. All studies but one were cross-sectional rendering demonstration of causation problematic. The reviewed literature also had drawbacks relating to exposure classification, confounding and non-attendance. Four studies showed an association between extensive use of precision grip and development of arthrosis of the distal interphalangeal joints of fingers. Two studies found an association between forceful gripping and the occurrence of arthrosis involving the metacarpophalangeal joints. Arthrosis of the proximal interphalangeal joints and first carpo-metacarpal joints was not related to any specific occupational task. Well-designed studies are needed to further elucidate this possible occupational hazard.

Objective:The aim of this study was to compare return rates to work between different groups according to the decision from the workers’ compensation.Method:Register data on disability benefits were used to describe return rates to work in Kaplan–Meier curves and association with decision on compensation claims. Disability benefits were granted by the municipalities independently of any compensation claim if sick-listed.Results:Claimants with ongoing claims were the group with the largest proportion remaining on disability benefits. Claimants with rejected claims returned to work at the same rate (occupational disease) or slower (industrial accident) than claimants with recognized claim without compensation the subsequent year and at a faster rate after decision.Conclusion:Compensation claims and proceedings of the workers’ compensation system probably increase time to return to work; other factors such as health and social difficulties, however, may explain some of these differences.

Low perceived work ability was characteristic; health and social issues explained only little of the differences in long-term benefits according to decision of workers' compensation system.
