ABSTRACT:
A fastener for the treatment of fractures and the materials for production thereof. The fastener having a head with a contact portion for an installation tool and an attaching part having a treaded portion. The threads of the threaded portion are 5 to 20 % of the height of the outer diameter of the thread. The material for producing the fastener is a blend containing a biodegradable base material and one or more copolymer additives so that at room temperature the ductility of the blend is substantially higher than that of the pure base material. The base material may be a biodegradable polymer and/or a copolymer.
