ABSTRACT:
Novel polymer compositions that are useful in the manufacture of medical implants, implants having osteogenic properties and methods of making said implants are disclosed. Polymer compositions comprise a base material including a polymer matrix of resorbable polymer(s) or copolymer(s), and N-methyl-2-pyrrolidone (NMP), wherein NMP is present in an amount imparting osteogenic properties for the composition.
