Patent ID: 7591823

Claim:
A system for the fixation of a bone fracture having a first bone portion and a second bone portion, said system including: a head component having a tip, cutting threads, fastening threads, and a tool attachment, wherein said cutting threads are operable for insertion into and termination within said first bone portion, wherein said fastening threads are operable for mating with a thread formed by said cutting thread, and wherein said tool attachment is operable to receive a cannulated driver; a flexible wire comprised of a thin metal having a first end and a second end, wherein said first end of said wire mates with said head component, said wire having a first interface along at least a portion of said wire, wherein said first interface includes a sawtooth configuration having a plurality of sawteeth, wherein said flexible wire is bendable without the use of tools and is able to be cut with a wire cutter, wherein said sawtooth configuration is configured such that one side of each tooth is substantially perpendicular to a surface of said wire and the other side of said sawtooth is substantially angular to said surface of said wire; and, a cap which includes threads on an outside surface to facilitate rotating said cap into said second bone portion, and wherein said cap includes a substantially flat end to minimize said cap from protruding from said second bone portion, wherein said cap is configured to mate with said second end of said wire, said cap having a second interface component including an inverse sawtooth configuration on an inner surface of said cap such that said cap is configured to translate along said wire with a portion of said inverse sawtooth configuration sliding over a portion of said sawtooth configuration, wherein said sawtooth configuration and said inverse sawtooth configuration are configured to allow said cap to translate along said wire in only one direction, and wherein said inverse sawtooth configuration includes a plurality of inverse teeth, and wherein said cap includes a center hole for receiving said wire and additional openings for facilitating expansion of said cap.
