Abstract

A orthopedic 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 ring from a biocompatible material, the annular ring having an outer sidewall, an inner sidewall, and a wireless communication device positioned between the outer sidewall and the inner sidewall,

aligning the annular ring with an acetabular cup that comprises a convex outer surface, a concave inner surface, and a rim surface defined between a distal end of the outer surface and a distal end of the inner surface, and

securing the annular ring to the rim surface of the acetabular cup such that the outer sidewall of the annular ring is congruent with the distal end of the outer surface of the acetabular cup and the inner sidewall of the annular ring is congruent with the distal end of the inner surface of the acetabular cup.

2. The method of claim 1, wherein forming an annular ring comprises forming an annular ring having a bottom surface that is congruent with the rim surface of the acetabular cup.

3. The method of claim 1, wherein forming an annular ring comprises molding the biocompatible material around the wireless communication device.

4. The method of claim 1, wherein forming an annular ring comprises forming an annular ring having a radio frequency identification (RFID) tag positioned therein.

5. The method of claim 1, wherein forming an annular ring comprises forming an annular ring from a dielectric material.

6. The method of claim 1, wherein forming an annular ring comprises forming an annular ring from a polymeric material.

7. The method of claim 1, wherein forming an annular ring comprises forming an annular ring from ultra-high molecular weight polypropylene.

8. The method of claim 1, further comprising positioning the wireless communication device into an inner chamber of the annular ring.

9. The method of claim 1, wherein forming an annular ring comprises forming an annular ring having a wireless communication device positioned therein that is configured to transmit at least one of identification data or sensor data in a frequency range of 30 megahertz to 3,000 megahertz.

10. The method of claim 1, wherein forming an annular ring comprises forming an annular ring having a wireless communication device that includes a dipole antenna.

11. The method of claim 1, wherein forming an annular ring comprises forming an annular ring having a wireless communication device that includes a straight line dipole antenna.

12. The method of claim 1, wherein forming an annular ring comprises forming an annular ring having a wireless communication device that includes a meandering line dipole antenna.

13. The method of claim 1, wherein securing the annular ring to a rim surface of an acetabular cup comprises attaching the annular ring to the rim surface with one or more screws.

14. The method of claim 1, further comprising:

forming a snap slot in the rim surface of the acetabular cup; and

forming a protrusion on a bottom surface of the annular ring;

wherein securing the annular ring to the rim surface comprises mating the protrusion to the snap slot.
