Synthetic bone or joint prosthesis - incorporates zones which are gradually absorbed by the body

Abstract

Abstract Biological implantation of bone or joint prostheses features liq. or plastics materials which are absorbable by the body and distributed in regular or irregular zones throughout its structure. These materials are adapted to form a load-bearing bond, immediately post-operatively, between bone and that portion of the implant which it is intended to fasten. The liq. or plastic material is hardenable. A patient is able to move aobut relatively soon after a bone or joint operatin since the bond between bone and implant rapidly becomes load-bearing. An accurate fit is obtd. without risk of displacement, or of adverse biological reaction. The material may be a plastics mass which hardens inside th body, e.g. PMMA or an epoxy resin, or a mineral base material, e.g. Zn-phosphate or an Si-phosphate, in which fibres (which may be oriented or random), or strand sections comprising a material that can be resorbed by the body, are dispersed. The resorbable material is pref. collagen, dentin, a bone granulate or bone-spongiosa.
