Abstract
BACKGROUND: The aim of this study was to develop and perform the 3D finite element analysis of a femoral head interior supporting device (FHISD).
MATERIAL AND METHODS: The 3D finite element model was developed to analyze the surface load of femoral head and analyze the stress and strain of the femoral neck, using the normal femoral neck, decompressed bone graft, and FHISD-implanted bone graft models.
RESULTS: The stress in the normal model concentrated around the femoral calcar, with displacement of 0.3556±0.1294 mm. In the decompressed bone graft model, the stress concentrated on the femur calcar and top and lateral sides of femoral head, with the displacement larger than the normal (0.4163±0.1310 mm). In the FHISD-implanted bone graft model, the stress concentrated on the segment below the lesser trochanter superior to the femur, with smaller displacement than the normal (0.1856±0.0118 mm).
CONCLUSIONS: FHISD could effectively maintain the biomechanical properties of the femoral neck.
