[Synovitis and bone changes induced by silicone prosthesis].

Authors report on the clinico-pathological analysis of cases of silicon granuloma, developed 5-15 years after the insertion of the prosthesis. It is thought on the basis of histological and electron microscopic examinations that the process of granulation already started, is augmented by the granules, newly arising from the attrition. The silicon granuloma causes not only the damage of the synovia but the destruction of the surrounding soft parts and bones too.
