- Influence of intramedullary nail length for femoral subtrochanteric fracture model
抄録
<p>Intramedullary nail fixation is one of the useful treatments for subtrochanteric fracture. The intramedullary nail used is selected from two types, long type and short type. In many cases, long intramedullary nail is applied to treatment of subtrochanteric fractures. However, there is discussion on application of long intramedullary nail from the viewpoint of minimally invasive. A middle intramedullary nail, which has an intermediate length between long type and short type, was developed. It is essential to conduct biomechanical investigations of the intramedullary nail systems subjected to various loads. The aim of this study was to investigate the influence of length of intramedullary nail for subtrochanteric fracture models with Seinsheimer classification IIB. Three types of intramedullary nail were considered: long type, middle type, and short type. Subtrochanteric fracture finite element (FE) models, which included the femoral fracture of Seinsheimer classification IIB and the intramedullary nail system, were developed. A 1-mm-thick callus layer was set in the gap between bone fragments of the femur. As a result of FE analysis, the effectiveness of middle intramedullary nail was indicated from the viewpoint of bone union and invasiveness.</p>
