Influence of Augmented Fixation to Dynamic Hip Screw on Trochanteric Lateral Wall

This paper focused on lateral trochanteric wall stress which is a contributing factor for the success of complex trochanteric fracture management with loss of medical bone support. Its aim was to assess performance of augmented fixations to Dynamic Hip Screw (DHS). The analysis was performed using Finite Element (FE) method, where the femoral bone and fixations were developed from reverse engineering technique. The boundary conditions were physiological loads with constraints at distal condyle. It was revealed that lateral augmented fixation i.e. trochanteric stabilization plate raised the trochanteric lateral wall stress that could be at risk of bone breakage.
