摘要：

This report discusses the Daphne(R) prosthesis for the metacarpophalangeal joint on the basis of the mechanical, chemical and biological performance of the materials employed. The Daphne(R) prosthesis is a mobile device. The main body is made of a new generation polymethylmetacrylate, while the hinge is made of AISI 316 L stainless steel. Biocompatibility tests were performed on the materials employed. Systemic toxicity, cytotoxicity and contact tests have given favourable results. Mechanical engineering tests have been used to investigate the performances and reliability of the selected materials, The polymethylmetacrylate used in Daphne(R) behaves in a ductile fashion, No mechanical failures were encountered in fatigue tests after 10 million cycles.
