System and methods for reducing interfacial porosity in cements

A device to reduce porosity at an interface between a bone cement and an orthopedic implant comprising:

• an oscillating device that drives movement along a selected axis of the implant, the movement having a selected frequency between 1 and 1000 radians/second and selected amplitude, the oscillating device in communication with a transducer to actuate movement of the orthopedic implant.

A device for implanting a prosthesis comprising:

• an actuator having a coupler that connects to a prosthesis, the actuator having an oscillator to generate oscillations at a determined frequency and amplitude, the prosthesis having an interface surface to be inserted into a material during implantation, the prosthesis being actuated at the determined frequency and amplitude to reduce porosity of the material at the interface surface and wherein the coupler comprises a thermal coupler connected to the prosthesis to control a temperature of the prosthesis.

A device to reduce porosity at an interface between a bone cement and an orthopedic implant comprising:

• an oscillating device that drives movement along a selected axis of the implant, the movement having a selected frequency and amplitude, the oscillating device in communication with a transducer to actuate movement of the orthopedic implant, wherein the insertion rate of the orthopedic implant is between 0.1 and 10 cm/sec.
