Dynamic Finite Element Analysis of Impulsive Stress Waves Propagating from the Greater Trochanter of the Femur by a Sideways Fall [PDF]

open access: yes, 2015
Fall accidents are a common cause of femoral fracture in the elderly. The greater trochanter of the femur is often subjected to impact loading by a sideways fall, and thus it is worth studying the impulsive stress waves propagating in the femur.
