US Patent 7037308 Implant device for applying compression across a fracture site

An implant for applying compression across a fracture site in a bone, the implant comprising a wire element having two spaced adjacent legs adapted to be implanted longitudinally in the bone across the fracture site. The wire element extends outwardly of the bone whereat the legs are bent and extend backwardly into juxtaposition with the legs in the bone and are joined by a U-shaped connecting portion. A tensioning device is engageable with the connecting portion and with a fixation device secured to the bone to apply force to the connection portion and produce tension in the wire element to develop compression across the fracture site.
