A Study to Verify if the Surgery for the Proximal Femur Fracture Can be Improved With the Help of a Navigation System

Stryker ADAPT®system (ADAPT, Stryker Leibinger GmbH \& Co. KG, Freiburg, Germany) is a computer navigation system which can reconstruct a 3D model of the femoral head from the positional information oriented by bidirectional fluoroscopic views. ADAPT shows the distance from the tip of the screw to the surface of the femoral head, tip-to-head-surface distance (TSD), and tip-apex distance (TAD) intraoperatively
