ABSTRACT:
A method of manufacturing a strong orthopaedic wire (30). A block (20) has an opening (26) with an interior diameter which is slightly larger than an outside diameter (28) of the wire (30). The wire (30) is placed within the opening (26) such that an end (36) of the wire (30) extends a predetermined distance (40) above the block (20). The extending end (36) is heated (e.g. by applying an electric current) until the metal from which the wire is made reaches the wire melting point. The molten metal is allowed to fall via gravitational force against the block (20), whereby the extending end (36) forms an enlarged end (42) on the wire (30).
