[Traumatic finger polyarthrosis in judo athletes: a follow-up study].

Osteoarthritis is the most common joint disease. In addition to known risk factors e.g. genetics, age and hormonal status it has been suggested that chronic-repetitive micro- and substantial (macro-) injury may play an important pathogenetic role. In a longitudinal case-study we examined Judo-players for clinical and radiological changes of the finger joints over the course of 16 years. All examined 8 players demonstrated soft tissue changes including Heberden nodes and radiological changes typical for osteoarthritis of the finger joints. Changes were symmetrical and were not restricted to joints with tendon ruptures or fractures in the anamnesis. Degenerative changes were progressive and more pronounced in active players. Subjectively, symptoms were usually mild. Extensive Judo seems to be a risk factor for the development of osteoarthritis of the finger joints due to chronic-repetitive micro- and substantial (macro-) injury.
