Orthopaedic prosthesis having a seating indicator

An acetabular cup comprising:

• an electrically conductive outer surface configured to confront a portion of a patient's acetabulum when the acetabular cup is implanted in the patient, the outer surface including a first channel defined therein that extends from a rim of the outer surface to a first location of the outer surface;
• a first electrical conductor positioned in the first channel, the first electrical conductor having a first end that extends out of the first channel at the rim of the outer surface;
• and
• a first push-button switch located at the first location of the outer surface, the first push-button switch having a first state wherein an electrical connection between the first electrical conductor and the outer surface is broken and a second state wherein an electrical connection between the first electrical conductor and the outer surface is established, and wherein the first push-button switch is biased to the first state.

An acetabular cup comprising:

• an dome-shaped outer surface configured to confront a portion of a patient's acetabulum when the acetabular cup is implanted in the patient, the dome-shaped outer surface including a channel defined therein that extends from a rim of the dome-shaped outer surface to a first location of the dome-shaped outer surface, the first location positioned near an apex of the dome-shaped outer surface;
• a switch located at the first location of the dome-shaped outer surface;
• a first electrical conductor positioned in the channel, the first electrical conductor having a first end that extends out of the channel at the rim of the dome-shaped outer surface and a second end electrically coupled to the switch;
• a second electrical conductor positioned in the channel, the second electrical conductor having a first end that extends out of the channel at the rim of the dome-shaped outer surface and a second end electrically coupled to the switch,
• wherein the switch has a first state wherein an electrical connection between the first electrical conductor and the second electrical conductor is broken and a second state wherein an electrical connection between the first electrical conductor and the second electrical conductor is established.
