Abstract

A orthopaedic implant comprises an acetabular cup and a wireless communication device. The wireless communication device is coupled to a rim surface of the acetabular cup. In one embodiment, a recess is defined in the rim surface and the wireless communication device is positioned therein. In another embodiment, the wireless communication device is positioned in an annular ring formed of a biocompatible material. The annular ring is coupled to the rim surface of the acetabular cup. The wireless communication device may be, for example, a radio frequency identification (RFID) tag or device.

Claims

1. A method for fabricating an orthopaedic implant, the method comprising:

forming an annular recess in a rim surface of an acetabular cup that is defined between an outer surface and an inner surface of the acetabular cup, the outer surface being configured to confront a portion of an acetabulum of a patient when the acetabular cup is implanted in the patient and the inner surface forming an inner cavity being configured to receive a bearing insert;

positioning a wireless communication device in the annular recess; and

securing the wireless communication device in the annular recess using a biocompatible compound.

2. The method of claim 1, wherein positioning a wireless communication device in the annular recess comprises positioning a radio frequency identification (RFID) tag in the recess.

3. The method of claim 1, wherein securing the wireless communication device in the annular recess comprises depositing an amount of bone cement in the recess.

4. The method of claim 1, wherein the inner surface of the acetabular cup has an annular outer edge, the outer surface of the acetabular cup has an annular outer edge, and the rim surface is substantially annular and planar and joins the annular outer edge of the inner surface to the annular outer edge of the outer surface.

5. The method of claim 4, wherein the annular recess in the rim surface has a substantially annular top profile.
