ABSTRACT
Fixation of femur head fractures often fails due to lag screw cut-out, especially in osteoporotic bones. This study correlates the experimental results of a new Trochanteric Plate of Contention (TPC), which may improve the resistance to the cut-out failure of internal fixation devices, and the well-known Dynamic Hip Screw (DHS) system. Generally, it is well accepted that the DHS is the first option in the treatment of stable femur fractures (Kokoroghiannis et al., 2012), as well as considered the implant that any new design should be compared with (Kouvidis et al., 2009). Hence, this study compares the strains, stresses, and displacements on these implants under compression tests. The data acquisitions were carried out using electrical and optical sensors.
