Bone fixation and fusion system

Abstract

A bone fixation and fusion system, that is preferably for use for joining bone ends together, and includes two members, that are each for individual turning into bone material, and include, respectively, male and female connector ends, that are for fitting together to connect together the member ends, bringing the bone material wherein they are turned into engagement and once connected resist being pulled apart. The connector ends are, respectively a cylindrical sleeve that extends axially from one member rear face, that includes a ring formed around the cylinder end and is cross cut longitudinally from that ring end, to form a spring collet, with the other connector end consisting of a cylindrical cavity that is formed longitudinally into the other member rear face for receiving the spring collet therein, which cylindrical cavity may include a groove, grooves or threads formed in the cavity wall that the spring collet ring end flexes into to provide a resistance to the two members being pulled apart. Each member includes a tool engaging end for receiving a turning tool fitted thereto, with threads formed around the member body, and provides, in the embodiment a twist drill as a member forward end for turning into the bone material. The system can be configured for use in a dental procedure where a ceramic or plastic crown or bridge can be formed on one member for installation onto the other member that has been turned into a patient's jaw, or one of the members can be configured as a bone joint fusion member.
