Abstract
The invention facilitates the fixation of bone fractures. In a particular embodiment, the head component includes a tip, cutting threads and mating threads which are inserted into the far cortex of the bone. A wire extends from the head component and exits from the near cortex. A cap device having a sawtooth inner surface is threaded over the wire having an inverse sawtooth outer surface such that the cap is restricted from backwards movement. Tension is then applied to the wire while the cap is tightened against or within the bone surface to thereby apply an appropriate amount of pressure between the surfaces of the fracture. The excess wire beyond the cap can then be removed.
Claims21
A system for facilitating a change in distance between objects, said system including:
- a head component configured to attach to one of said objects;
- a wire having a first end and a second end, wherein said first end of said wire is configured to mate with said head component;
- and,
- a cap configured to mate with said second end of said wire.
A system for the fixation of a bone fracture having a first surface and a second surface, said system including:
- a head component configured to attach into said first surface of said bone;
- a wire having a first end and a second end, wherein said first end of said wire is configured to mate with said head component;
- and,
- a cap configured to mate with said second end of said wire.
A cap device having an outside surface and an inside surface, said inside surface including an interface component and said outside surface including cutting threads.
A method for facilitating a change in distance between a first and second surface, said method including:
- providing a head component mated with a wire having a first interface component;
- inserting said head component into said first surface;
- extending said wire through said second surface;
- and,
- threading a cap having a second interface component over said first interface component of said wire.
