Abstract : Static and dynamic experiments were conducted to study the failure loads and fracture patterns of human proximal femur bones, that are intact and core drilled. This was done to assist orthopedic surgeons better understand the effects of core drilling into the femoral head to remove osteonecrosis. Unlike pervious studies, where only static tests were conducted, dynamic tests were preformed to better simulate a lateral fall. A Finite Element Analysis (FEA) was also completed to understand stress distributions in the proximal femur when subjected to static and dynamic loads. Previous PEA models of the femur analyzed static loads only with just a core drilled hole at the lesser trochanter. This PEA model examines various sizes of hole diameters and locations on the greater trochanter as well as having the model loaded statically and dynamically.
