Arthroses of the finger joints and thumb saddle joint and occupationally related factors

In a one-to-one matched case control study, 37 cases with rhizarthrosis (31 female, 6 male) and 44 cases with osteoarthritis in the finger joints (35 female, 9 male) were compared to their matches equal in sex and age regarding occupational strains. For calculating the odds ratios matching was maintained. In females the risk of rhizarthrosis was elevated for typists (OR 5.0, CI 1.27-19.59) and for work involving dexterity (OR 2.0, CI 0.77-5.23). In both sexes an elevated odds ratio for osteoarthritis in the finger joints was found for repetitive work (OR 3.8, CI 1.52-9.49).
