Abstract:
Objective To illustrate the application of fluoronavigation in Gamma nailing—a common surgical procedure in treatment of intertrochanteric fracture of femur and to compare the newly designed Gamma-3 system for navigation with the Gamma-AP system. Methods 66 patients with intertrochanteric fractures underwent Gamma nailing (40 Gamma-AP and 26 Gamma-3) under fluoronavigation guidance. An observer recorded the different intra-operative parameters. Results The Gamma-3 group showed superior results of shorter operation time (averaging 32 minutes), smaller surgical wound size (5cm), less X-ray requirement during procedure (7 times) and at the same time better lag screw position (Tip-Apex-Distance 17.9 mm). Conclusions Fluoronavigation can facilitate gamma nailing as a minimally invasive surgery because of its accurate guidance to nail insertion and lag screw positioning, a smaller surgical wound and minimized X-ray exposure suffered by operation theater staff. The Gamma-3 system has shown better results than the Gamma-AP system because of its navigation-specific design.
