Occupational use of precision grip and forceful gripping, and arthrosis offinger joints: A literature review

A systematic review of arthrosis of finger joints in relation to occupation al exposure revealed 11 epidemiological studies and 13 case reports. All st udies but one were cross-sectional rendering demonstration of causation pro blematic. The reviewed literature also had drawbacks relating to exposure c lassification, confounding and non-attendance. Four studies showed an assoc iation between extensive use of precision grip and development of arthrosis of the distal interphalangeal joints of fingers. Two studies found an asso ciation 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 oc cupational task. Well-designed studies are needed to further elucidate this possible occupational hazard.
