Table 1 The comparison of stress and displacement between two models and the number of nodes and elements in each model (The model fixed with T-shaped plate was designated as ‘P’ and the model fixed with three percutaneous screws was designated as ‘S’. The data was listed in the form of ‘mean ± SD; number of nodes’.)
