Abstract
Composite bones are often used in testing of orthopedic implants due to their relative ease of use and low inter-specimen variability when compared to cadaveric bones. Tests were run to ensure that the composite bones remained an acceptable model for cadaver bones throughout surgical manipulation. Composite (n=6) and cadaver (n=6) femur specimen were subjected to a total hip arthroplasty (THA). Flexural rigidity, axial stiffness, and axial strain measurements were taken at various stages in the surgical process. The composite and cadaver specimen were not found to behave similarly in either flexural rigidity or axial stiffness tests. The results showed a general inconsistency in the behavior of the specimen, making the composite bones an imperfect model. No residual strains or creep in the axial strain tests were found for either composite or cadaver bones; this supports the use of composite bones to reduce unpredictability in testing results.
