ABSTRACT:
A closure for an open headed medical implant, such as a bone screw. The closure having a cylindrical body having an axis of rotation and also having a threaded radially outer surface. The body having a plurality of bores that open onto a top surface of the body and that are parallel to but spaced from the axis of rotation. In one embodiment the closure also has a break-off head centrally attached by a neck to the top surface of the body. Preferably, the body also includes an axial threaded bore that extends from a bottom to the top of the surface body, but that is only exposed when the break-off head breaks away. In another embodiment a tool is used to insert the closure in the implant without a break-off head and a central threaded bore of the closure receives a set screw.
