| pubmed-article:2990618 | pubmed:abstractText | An acrylic-headed prosthesis was removed after 30 years and analyzed for material deterioration. Although the acrylic head showed some wear and minor corrosion of the cobalt-chromium stem was found, tissue responses were not significant, indicating that use of these materials is consistent with the long-time survival of a prosthesis. | lld:pubmed |
