Subject specific finite element analysis of stress shielding around a cementless femoral stem

Bone stresses before and after insertion of two commercially available distal ulnar implants using finite element analysis

“…27 To our knowledge, only one other recent study investigated the use of multiple subject-specific FE models to predict stress shielding. 28 A limitation of this work is that only one loading scenario was investigated (transverse bending loads in neutral position). Future studies should incorporate other load values and multiple simulated forearm rotations.…”

Patient specific quantitative analysis of fracture fixation in the proximal femur implementing principal strain ratios. Method and experimental validation

“…Clinical applications have been predominantly aimed at failure prediction of intact bone models under static loading (Bessho et al, 2007;Cody et al, 1999;Keyak, 2001; and biomechanical responses to total hip implant insertion (Huiskes et al, 1987;Pettersen et al, 2009;van Rietbergen and Huiskes, 2001). Numerous studies have reported on the development, validation and automation of patient specific FE modeling techniques from quantitative CT data sets (Helgason et al, 2008;Keyak et al, 1993;Schileo et al, 2007;Taddei et al, 2004Taddei et al, , 2006Zannoni et al, 1998), however, these investigations primarily focused on strategies for element based application of bony material properties at different densities based on Young's modulus relationships for intact bone models.…”

In Situ Titanium Alloy Elaborated by Selective Laser Melting of Ti and Nb Mixed Powder

“…A modulus of elasticity similar to that of cortical bone is particularly appreciated in the manufacture of implants and prostheses because it minimizes the discontinuity in elastic properties at the implant / bone interface [5,6] and thus reduces the stress shielding phenomenon following a joint replacement.…”
