Abstract:
1. A method for establishing a connection between a pin and a bone, the method comprising the steps of: inserting a pin into a bone such that an anchor coupled to the pin proximate a distal tip region of the pin is seated in the bone without the anchor threadably engaging the bone; adjusting the pin and anchor to establish a secure interface between the anchor and the bone without the anchor threadably engaging the bone; wherein after the pin and anchor have been in the bone and the interface between the anchor and the bone has loosened, then further adjusting the pin and anchor to re-establish a secure interface between the anchor and the bone without the anchor threadably engaging the bone; and wherein the further adjusting step further comprises, at least in part, radially expanding a portion of the anchor in a direction generally perpendicular to a longitudinal axis of the pin to re-establish the secure interface with the bone.
