[Early isotopic synoviorthesis during rheumatoid polyarthritis (RP)].

The authors report the results of 1258 chemical synovectomies carried out in subjects with rheumatoid polyarthritis on joints at Steinbrocker stage I and of 470 chemical synovectomies carried out during the first year of evolution of rheumatoid polyarthritis. Comparison with the results of chemical synovectomy carried out later demonstrate the superiority of early chemical synovectomy.
