Discussion
fracture
Through mechanical experiments and clinical trials, we have found that the mechanical advantages of Gamma nail fixation are not as good as those of conventional CCS fixation. However, the mechanical properties of Gamma nail fixation combined with one cannulated screw perpendicular to the fracture line are much better than those of Gamma nail fixation and CCS fixation. Given this, we further investigated the clinical efficacy of Gamma nail fixation with a cannulated screw and found that it was not clinically superior to CCS fixation.
