Abstract:
Various aspects of the present invention provide an apparatus and a method of removing an orthopedic implant from a patient. In one embodiment, the method includes cycling the temperature of at least a portion of the orthopedic implant between a first temperature and a second temperature that differs from the first temperature. In one embodiment, the first temperature is above 0° C. and the second temperature is below 0° C. The temperature cycling causes a thermal expansion differential between at least a portion of the orthopedic implant and material in a region contacting the orthopedic implant. In one embodiment, the thermal expansion differential is of an extent sufficient to cause physical separation of at least a portion of the surface of the orthopedic implant from material contacting the surface of the orthopedic implant.
