Objectives: To determine if rock climbing is a significant factor in the development of Dupuytren's disease in men, and, if so, what is the most likely related factor. Methods: Questionnaires were distributed to all 1100 members of the Climbers' Club of Great Britain. These detailed basic information about the climber, the presence of Dupuytren's disease, and any known risk factors for its development. Results: About half (51%) of the questionnaires were returned. The respondents were almost entirely male. It was revealed that 19.5% of male climbers had developed Dupuytren's disease. There was a significantly higher life time intensity of climbing activity in those with the disease. An earlier age of onset of the disease was found in climbers compared with the general population. Conclusions: This study further strengthens the hypothesis that repetitive trauma to the palmar fascia predisposes to the development of Dupuytren's disease in men.
