Abstract
This study aimed to investigate the mechanical performance of different cannulated hip screw size in the treatment of femoral neck fracture via finite element method. The 3D model of a proximal femur was constructed CT data of human lower limb. The femoral neck fracture was stimulated with a 40o cut from the anatomical femoral axis. This model was treated with multiple cannulated hip screws with three different sizes – 6.5, 7.0 and 7.3mm. The chosen arrangement for this particular study was a triangle configuration. All analyses were performed using stair climbing loads. The results showed for different sizes different stress distribution. The 7.3 mm cannulated hip screw option for treatment of femoral neck fracture
