Intralesional curettage versus prosthetic replacement for bone tumors — a finite element analysis case of limb salvage simulation in biomechanics

To compare mechanical properties of femoral tumor treatments so that better operative strategy for limb tumors surgery is optimized. Fourteen femoral CT images were randomly selected to rebuild 3D models by MIMICS. They were then executed by reverse engineering softwares for simulative modes. Mode #1: Intralesional curettage with cement filled plus fixator; Mode #2: Distal femur resection with tumorous prosthesis replaced. Finally, the...
