Abstract
A flexible bone screw for insertion into the intramedullary cavity of a fractured bone facilitates enduring fixation of the fracture. The flexible bone screw includes a substantially smooth shaft and a threaded portion positioned at one end of the shaft, wherein the outer diameter of the threaded portion is greater than the shaft diameter and the length of the threaded portion is about 20% of the overall length of the flexible bone screw or less.
Claims20
A method for repairing a bone fracture, comprising the steps of:
- drilling a hole through a side of the bone to expose an intramedullary cavity of the bone;
- inserting a flexible bone screw through the hole into the intramedullary cavity of the bone, the flexible bone screw having an elongated shaft and a threaded portion at a leading end thereof;
- and
- rotating the bone screw to advance the threaded portion of the bone screw with associated elastic bending of the shaft, substantially along a longitudinal axis of the bone;
- and
- inserting the tip of the threaded portion past the location of the bone fracture.
A method for repairing a bone fracture, comprising the steps of:
- drilling a hole through a side of the bone to expose an intramedullary cavity of the bone;
- inserting a flexible bone screw through the hole in a first direction, into the intramedullary cavity of the bone, the flexible bone screw having an elongated shaft and a threaded portion at a leading end thereof;
- and
- rotating the bone screw to advance the threaded portion of the bone screw with associated elastic bending of the shaft, in a direction that is along a longitudinal axis of the bone;
- and
- inserting the tip of the threaded portion past the location of the bone fracture.
A method for repairing a fracture of a humeral head, comprising the steps of:
- drilling a hole through a side of a humerus bone to expose an intramedullary cavity of the humerus bone;
- inserting a flexible bone screw through the side of the humerus bone into the intramedullary cavity of the humerus bone, the flexible bone screw having an elongated shaft and a threaded portion at a leading end thereof;
- and
- rotating the bone screw to advance the threaded portion of the bone screw with associated elastic bending of the shaft, along a direction towards the humeral head;
- and
- inserting the tip of the threaded portion past the location of the fracture.
