Abstract：Objective To explore the effectiveness of application of the orthopedics robot navigation positioning system in assistance of hollow screw internal fixation for femoral neck fractures. Methods Firstly, the main control system of the robot would establish a FEA (Finite Element Analysis) model of percutaneous hollow screw internal fixation for femoral neck fractures. Then, physicians could perform the surgeries under the guidance of the positioning implementation system. Results Anatomical reduction of fractures was achieved in all the 23 cases of surgeries. The deviation of the maximum degree of parallelism was less than 1.2 mm for the guide pin (diameter: 3 mm). The C-arm fluoroscopy time was 15.7 s; while, the average number of radiation times was 23.1. Conclusion The robot-assisted trauma orthopedics surgery proven its advantages of accurate positioning, reliable fixation and safe operation, which could greatly and effectively reduce the intra-operative X-ray exposure time and radiation harm for patients and medical staff.
