Abstract
© Published under licence by IOP Publishing Ltd. Proximal femur is connected between pelvis and the lower extremity to carry the body weight that transfer from the upper body to the lower part. The patients, had the proximal femur bone tumor had a problem in daily activities. The most treatment for bone tumor has two methods as radiation and surgery method. The surgeon removed the bone tumor, replaced with the other proximal femur and fixed by dynamic hip screw and four screws fixation. This study aim to analyse the postoperative results after surgery with finite element analysis, were divided into six cases as the same size proximal femur, 15% and 30% small proximal femur, 15% and 30% large proximal femur and the same size proximal femur constructed by polymethyl methacrylate (PMMA). The result were shown the maximum strain on the small size higher than another cases under walking and stair-climbing load and the same size proximal femur constructed by PMMA had the lowest maximum equivalent of total strain. The surgeon should be replacing the proximal femur with the same or the larger size of femur or the same size constructed by PMMA for a good clinical result.
