Abstract:
A two part bioerodible bone cement system which, upon mixing of the system parts, forms a bioerodible polymeric semi-IPN alloy, said two part cement system consisting ofa) a first part comprising a first bioerodible polymer capable of producing acidic products upon hydrolytic degradation, crosslinking initiator, and a therapeutically effective amount of a biologically active or therapeutic agent, wherein said biologically active or therapeutic agent is in a protective coating of said first bioerodible polymer; andb) a second part comprising a second bioerodible scaffolding polymer, which upon crosslinking provides a biopolymeric scaffolding or internal reinforcement for said semi-IPN alloy, and crosslinking agent for said second bioerodible scaffolding polymer.
