Abstract

Fixation of a bone fracture may be accomplished by screw driving a threaded pin into the bone, typically in a manner to cause the pin to advance across the fracture area of the bone. It is also common for a pair or more of said pins to be driven into the bone in the manner described above. The threaded pin or pins each may have a cable secured to the pin, extending outwardly from the proximal pin end. One then wraps the cable or cables around the bone to provide external securance for fixation of the bone fracture. A pair of cables used in this process may be secured together under tension by a crimp. Otherwise, a single, free cable end may be secured to a separate pin or other anchor as desired.

Independent Claims | See all claims (14)

  1. 1. The method of fixation of a bone fracture, which comprises:screw driving a pair of threaded pins into said bone in spaced relationship, each of said threaded pins having a cable secured to said pin and extending outwardly from the proximal pin end to a free cable end; wrapping said bone with said cables to promote fixation of said bone fracture; and securing said cable ends together.
  2. 5. The method of fixation of a bone fracture, which comprises:screw driving a threaded pin into said bone in a manner to cause said pin to advance across the fracture area of the bone, to provide internal securance for fixation of said bone fracture; said threaded pin having a cable secured to said pin and extending outwardly from the proximal pin end; and wrapping said cable around said bone to provide external securance for fixation of said bone fracture.
  3. 9. A device for fixation of bone fractures, which comprises: a pin defining a bone penetrating point at one end thereof and screw threads defined on said pin adjacent said point; a multistrand cable attached to said pin and extending from the end of said pin opposite said one end outwardly therefrom to an outer cable end; a polygonal driver member carried on said opposite pin end and surrounding said cable, to engage a rotary pin driver, said pin being solid and lumen-free along the majority of its length.
  4. 13. The method of fixation of a bone fracture, which comprises:screw driving a threaded pin into said bone in a manner to cause said pin to advance across the fracture area of the bone, to provide internal securance for fixation of said bone fracture, and threaded pin having a cable secured to said pin and extending outwardly from the proximal pin end; and wrapping said cable around said bone to provide external securance for fixation of said bone fracture, said pin being completely advanced into said bone during said driving into the bone, said cable extending centrally through a pin driver as the pin driver advances said pin into the bone.
