Computational Study in Effects of Nail- and Plate-Implants on the Treatment of Pertrochanteric and Intertrochanteric Fractures

CODEN: MPCACD

Abstract

This research is to evaluate and identify the most suitable implants for the treatment of trochanteric fractures. Using finite element analysis method (FEM), we developed trochanteric-fractured 3D models based on Arbeitsgemeinschaftfür Osteosynthesefragen (AO) classification. Three types of trochanteric fractured models were assembled with four different implants leading to 12 models. The trochanteric fractures were identified as 31-A1.1, 31-A2.1, and 31-A3.1 fracture fixed with short proximal femur nail antirotation (PFNA), long PFNA, dynamic hip screw (DHS), and PF-locking compression plate 4.5/5.0. The assembled models were calculated and analyzed using the FEM. The simulation illustrated the von Mises stress distribution and displacement on 12 models. The intramedullary nail implant is superior to the external plate. Short PFNA and DHS are suitable to fix pertrochanteric fractures; long PFNA is considered a priority to treat intertrochanteric fractures.
