Abstract
A system for and methods of easily and securely inserting and removing a fastener usable during orthopedic surgery to promote proper healing of injured bone are disclosed. In at least one embodiment, the invention provides a system for positive, complete tri-modal retention of a bone media fastener element by a bone media fastener driver element so that three types of positional divergence of the driver relative to the fastener—bi-axial, bi-rotational, and bi-lateral—may be prevented. At least one embodiment of a bone media fastener apparatus may comprise a shaft element, a threaded bone engagement element, and a head element that itself may comprise a fastener-side, positive, complete tri-modal retention element that is engageable with a driver-side, positive, complete tri-modal retention element of a bone media fastener driver element to prevent bi-lateral divergence, bi-rotational divergence, and bi-axial divergence.
