The method, characterized in that, the powdered chitosan is dissolved in water to obtain a 5% solution, into which a 70-90% acetic acid is added and after the formation of the blank intramedullary nail and carrying a coagulating bath and neutralization bath it is subjected to a crosslinking bath in a solution formed from 0.5 to 2% of sodium tri-polyphosphate and 0.5% to 3% Na3PO4 for 24 to 48 hours in temperature of 50° C. to 140° C. and then it is subjected to the drying process, for a period of 6 to 10 days, and finally the surface of the blank is treated to form the intramedullary nail. The surface treatment is carried out until the surface of the intramedullary nail contains at least 20%-40% of the pore of the depth of 0.1 mm to 1 mm.

A polymeric fastener for use in the construction industry for fastening wood and other basic materials together. The polymeric fastener can be formed in the basic shape of a nail and/or a staple-like fastener. Preferred embodiments of the polymeric fastener include a hardened binder embedded with a filler and/or a core for adequate strength as required for use with a delivery device powered by pneumatics, hydraulics, or other mechanical systems.

A collated strip of polymer fasteners is provided, the collated strip comprising a plurality of spaced apart polymer fasteners, each made from a polymer material, each polymer fastener comprising a head and a shank extending therefrom, the shank terminating at an end; and a connector integrally formed with, and extending transversely across, the shanks of each polymer fastener, the connector being arranged to separate the fasteners, including the heads of each fastener, from each other. In an embodiment, a portion of the shank is threaded, the threaded portion of the shank being either screw-threaded or ring-threaded. The connector comprises a pair of spaced apart collating threads to integrally connect the shanks of the polymer fasteners together, to define the collated strip of polymer fasteners. In one version, the connector is made from the same polymer material as the polymer fasteners.
