Abstract
The present invention provides a system and a method for reducing pores, or air pockets, that form at the interface between the material used to attach or adhere the surface of a component, such as a prosthesis, to a site. A preferred embodiment of the invention includes an actuator that controls a coupler which transmits energy to a prosthesis being inserted into a material to reduce porosity at an interface between the prosthesis and the material. The system of the present invention can include an oscillating hand-held device that vibrates the stem component of an orthopedic prosthesis at a particular frequency and amplitude. The device is typically held by the hand of the surgeon, who guides the vibrating prosthesis into the cement-filled medullary cavity.
