A Comparative Evaluation Of Cadaveric And Composite Femur Models For Total Hip Arthroplasty, Anderson Lynn Adams

Graduate Theses - Biology & Biomedical Engineering

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 …
