An improved external compression bone fixation device for use in the treatment of fractures. The device provides compression on a bone fracture until the fracture has healed. By threading a screw with a threaded shank into the far side of the fracture and then threading a second screw into the other portion of the fractured bone and also onto the shank of the first screw, the fracture is drawn together. When healing has been completed, the screws are removed. The entire procedure can be performed from outside the fractured limb, and a second surgical procedure is not necessary to remove the fixation device after healing.
