The Effect of Cementation and Autogenous Bone Grafting on Allograft Union and Incorporation

Abstract

During this time period the in vitro testing has been completed. Cadaver bones were prepared with a 6-cm segmental bone graft (autograft to simulate the best fit possible with an allograft) and then stabilized with an interlocking nail placed down the medullary canal, including 2 screws placed above the graft and 2 screws below the graft. To this construct, the presence or absence of bone cement around the nail through the graft segment was tested biomechanically. This test simulates the time zero point, before any bone healing has occurred. The data has yet to be statistically analyzed. However, it appears that the 2 constructs performed similarly for the various mechanical tests conducted (compression, bending, and torsion).
