Abstract
A prosthetic screw system that includes a prosthetic screw for at least partial insertion into a bone and/or cartilage. The prosthetic screw includes a head and a lower portion connected to the head. The prosthetic screw system also includes a set of head-pieces that can be connected to the head of the prosthetic screw. The head-pieces have differing configurations that are designed to be connected to different types of components of a prosthetic system. The universal connection arrangement between the prosthetic screw and the set of head-pieces enables the prosthetic screw to be customized for connection with a variety of components of a prosthetic system. The head-pieces can alternatively or additionally include a mechanical and/or electrical mechanism that provides one or more substances (e.g., medicine and/or other biological agent, etc.) and/or electrostimulation to a surgical site.
