Devices and methods for repairing bone fractures

Abstract

Devices and methods for repairing bone fractures are described herein. A pin directing device for steering a flexible bone screw is disclosed. A fluted entry tool for penetrating into cancellous bone without penetrating the far cortex of the bone is disclosed. A flexible bone screw having a rotational position marker positioned thereon at a terminal twenty-five percent of the shaft is disclosed. A flexible bone screw comprising at least eighty percent cold work hardened alloy is disclosed. A pin bending clamp having a transverse hole in the jaws is disclosed. A flexible bone screw with a cortex climbing thread portion at the tip, which is helicoid, is also disclosed.

What is claimed is: 
     
         1 . A threaded orthopedic device, comprising:
 a flexible shaft; and   a threaded portion that is disposed on one end of the shaft,   wherein the threaded portion includes a tip region with a tip thread, a body portion with a body thread that has a major diameter that is equal to or greater than the largest major diameter of the tip thread, and a transition point disposed where an edge surface of the tip thread meets an edge surface of the body thread, and   wherein the tip region is disposed within a cone that is 1) centered on a longitudinal axis of the shaft and 2) passes through the transition point.
