Stress distribution findings. A stress distribution of model a (the femoral neck fracture healing model with IFs); B the stress distribution of the IFs in model a; C stress distribution of the model b (the healing model); D stress distribution of model c (sclerosis around screws model with IFs); E stress distribution of the IFs in model c; F stress distribution of model d (sclerosis around screws model). IF, internal fixation
