<p>This invention is a cannulated tamp (10) for preparing a cavity in a femur to receive a prosthesis has a thin sidewall (20) with perforations (32), openings (26, 28) at the proximal, and distal ends. During the process of tamping bone graft material, it is positioned over a guide wire (30) which extends through the openings at the proximal, and distal ends. After completion of the tamping, the guide wire is removed, a perforated tubing (50) attached to a vacuum pump (P) is inserted through the openings at the proximal, and distal ends to withdraw liquids from the prepared cavity.</p> |
