Abstract: An electrical stimulation anchor is configured to be electrically coupled to a power source, such as a transducer, that is external to the electrical stimulation anchor. The electrical stimulation anchor can include a bone anchor that is configured to be secured to a bone. The bone anchor can define a first electrode, a second electrode, and an isolating portion between the first electrode and the second electrode. The electrical stimulation anchor can further include a connection unit attached to the bone anchor. The connection unit can define a first contact member that electrically connects to the first electrode, and a second contact member electrically isolated from the first contact member. The second contact member can be electrically connected to the second electrode. The first and second contact members are configured to draw electrical current from the transducer so as to establish a voltage differential between the first and second electrodes.

Abstract: An electrical stimulation screw, for instance a cortical screw or a locking screw, is configured to generate an electric field in response to a magnetic field. The electrical stimulation screw can include a head body and a head ring that surrounds the head body. The electrical stimulation screw can further include a tip opposite the head along the central anchor axis, and a shaft that connects the head to the tip. In one example, the shaft can define a shaft body that is monolithic with the head body, so as to increase the mechanical strength of the screw without compromising the strength of the electric fields that can be generated by the screw. The head body can define a cavity that is configured to receive a driver so as to rotate the head body and the shaft body about a central anchor axis.
