ABSTRACT:
An improved method for reinforcing a prosthetic implant and an implant product are provided. The method includes embedding a support structure in a bed of bone cement surrounding the distal end of a prosthetic device. The support structure counteracts hoop-stress imparted to the implant, decreases creep of the bone cement, and further reinforces the bone cement bed. In various embodiments, the support structure can be in the form of a metal coil or in the shape of a wire mesh. Prior to being implanted, the support structure can be precoated with bone cement or can be prefabricated with a prosthetic device.
