ABSTRACT:
A reinforcing technique for bone cement used in the anchoring of prosthetic devices. The reinforced bone cement includes oriented reinforcement formed of a continuous fiber-like material that is embedded in the bone cement between at least a portion of the outer surface of the prosthetic device and the surrounding bone that defines the cavity in which the device is implanted. The reinforcement is preferably a polymeric mat embedded in a thin layer of bone cement forming a precoat on the outer surface of the implant.
