A physical model for simulating fusion of impaction-grafted morselized cancellous bone

This article describes a method to simulate fusion of morselized cancellous bone. The morselized cancellous bone is mixed with an epoxy adhesive, in e mpirically determined proportions. The mixture is then impacted into a cons truct. When the epoxy cures, the morselized material fuses into a cohesive, contiguous structure with a compressive modulus equivalent to that of inta ct cancellous bone. This model can be used to study biomechanical aspects o f fused impaction grafts. (C) 2001 Elsevier Science Ltd. All rights reserve d.
