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: The invention relates to a hip joint prosthesis comprising a shaft-like section that can be inserted into a femur, and a proximally arranged end cap assembly which closes a hollow space of the hip joint prosthesis.
