A cannulated tamp (20) having a proximal compressive flange (23A) is used for compacting bone graft material in a femur having a cavity being prepared to receive a femoral prosthesis. The tamp (20) of the present invention is particularly useful in achieving uniform compaction in the proximal area of the femur. The compressive flange (30) may be monolithic with the stem of the tamp (20) or may be a separate modular member (42) affixed thereto. Under one embodiment, a series of passageways (168) are provided for attachment to a source of vacuum for evacuating blood and other fluids from the prepared cavity.

Pilon rainuré (20) présentant un rebord compresseur proximal (23A), utilisé pour tasser une matière osseuse greffée dans un fémur dans lequel on a ménagé une cavité destinée à recevoir une prothèse fémorale. Ce pilon (20) est particulièrement indiqué pour obtenir un tassement uniforme dans la zone proximale du fémur. Le rebord compresseur (30) peut faire corps avec la tige du pilon (20) ou peut être un élément modulaire séparé (42) fixé à cette même tige. Dans une variante, une série de passages (168) permettent, par leur raccordement à une source de vide, l'évacuation du sang et d'autres fluides de la cavité préparée.
