Abstract
A relatively massive annular body is driven in radial-mode resonant oscillation by an ultrasonic driver that is fixed to the periphery of the annular body, with the axis of its ultrasonic drive oriented for intersection with the central axis of the annular body. A selected chucking device within the bore of the annular body is adapted to engage part of a prosthetic device, to which the resonant oscillation is imparted, for melting bone cement and for severing bony ingrowth into the prosthetic, thus permitting immediate retraction of the prosthetic from its pre-existing implantation in a living bone.
