Abstract
A bone fixing device and a method of distracting a fracture are described. The bone fixing device has threads at both a leading end and a trailing end, and the pitch of the threads are greater at the trailing end. This causes the leading end of the bone fixing device to travel more slowly through the bone than the trailing end, which loads the threads of the screw to put the screw under compression, so that the threads bite more effectively into the bone. A jig and method for insertion of two bone fixing devices are also described. The jig defines parallel planes of insertion which cross when viewed in a direction perpendicular to the parallel planes.
