Orthopaedic prosthesis having a seating indicator

摘要

An orthopaedic prosthesis has a curved outer surface configured to abut a patient's bone when the orthopaedic prosthesis is implanted therein. The outer surface can be electrically conductive. A channel is defined in the outer surface and extends from a rim of the outer surface to a location on the outer surface. At least one electrical conductor is positioned in the channel and extends outwardly from the channel at the rim of the outer surface. A switch is positioned at the first location and is configured to establish an electrical connection between the electrical conductor and the outer surface and/or another electrical conductor when the first location of the outer surface contacts the patient's bone. The switch may be embodied as an end of the electrical conductor or a more complex switch such as a push-button type switch.
