Mechanical Properties of the Gamma Nail + 
fracture
Given this, we added one CCS perpendicular to the fracture line to the Gamma nail fixation and tested its mechanical properties. The results showed that Gamma nail + CCS fixation was significantly stronger than the other two groups in all three tests, and there was no femoral head rotation after the ultimate load test. Therefore, we conclude that Gamma nail combined with one CCS perpendicular to the fracture line can enhance the strong fixation effect of the Gamma nail while compensating for the poor antirotation effect, thus demonstrating a far better mechanical effect than the three CCSs.
