ABSTRACT:
Disclosed is a method and apparatus for removing a polymethylmethacrylate or other cement plug from the medullary canal during hip-revision surgery. In accordance with the method, a portion of the PMMA plug is softened and a plug removal tool is advanced through the softened portion to become imbedded in the plug. The plug is permitted to harden around the tool, and the tool is withdrawn thereby pulling the plug with it. Softening may be accomplished by conducting ultrasonic energy through the removal tool tip, or by other means. Hardening is accomplished by removing the heat source and permitting passive cooling of the material, or by accelerating cooling of the material through the use of a heat sink or a circulating media such as a compressed gas. Also disclosed is a self-cooling tool tip.
