Clinical Application of Orthopedic Robot Navigation and Positioning System

摘要

To investigate the orthopedic robot navigation system fracture clinical application of the cannulated screw fixation in femoral neck. 40 patients were randomly divided into the robot operation group and the traditional operation group, namely 20 cases for each group. The frequency of fluoroscopy, the time of operation and the number of drill holes in the two groups were measured. The parallelism between the cannulated screws was measured. The deviation angle between the cannulated screws and femoral neck-shaft angle or anteversion angle was measured. The difference between the two groups was compared with the statistical methods. There were significant differences in the operation time, the frequency of fluoroscopy and the number of drill holes in the two groups (P <0.05). The difference of the parallelism and the deviation angle between the cannulated screws in the two groups were statistically significant (P <0.05). The operation time was short, the radiation in the operation was less, the mechanical distribution of the cannulated screws was better, the safety and accuracy of the operation were improved, when the orthopedic robot navigation and positioning system assisted the cannulated screw fixation in femoral neck fracture.
