Abstract：
:This article describes a method to simulate fusion of morselized cancellous bone. The morselized cancellous bone is mixed with an epoxy adhesive, in empirically determined proportions. The mixture is then impacted into a construct. When the epoxy cures, the morselized material fuses into a cohesive, contiguous structure with a compressive modulus equivalent to that of intact cancellous bone. This model can be used to study biomechanical aspects of fused impaction grafts.
