Matrix material for fixing bone fractures - consisting of a copolymer of hydrophilic and hydrophobic monomers reinforced with resorbable non-non-toxic fibres

Abstract

Abstract New biodestructive material for use as a joining element for bone tissue is a matrix of (A) a non-toxic resorbable polymer consisting of hydrophilic and hydrophobic members and (B) a reinforcing component made up of non-toxic, resorbable fibres. The polymer component of the matrix pref. contains 20-40wt.% hydrophilic monomer. Pref. hydrophilic monomers are N-vinyl-pyrrolidone and acrylamide. Pref. hydrophobic components of the polymer are alkyl acrylates, esp. methyl methacrylate. The reinforcing fibre (pref. constituting 50-80wt.% of the matrix.) pref. consists of filaments of polyamide, oxycellulose and/or polyvinyl alcohol. Used in the form of rods, clamps, plates etc. for fixing bones after fractures etc. The new material facilitates fixing of fractured bones, but is gradually absorbed so that surgical removal is not necessary. The material is easily worked, so that the shape and size of the fixing elements can be tailored to the individual case.
