Strengths and Limitations

femoral neck fractures, DHS
This is the first study to compare the mechanical properties and clinical results of Gamma nail combined with one cannulated compression screw in the treatment of femoral neck fractures, which provides a reference for the future use of Gamma nail in the treatment of severe femoral neck fractures.The number of patients included in this study was small, and the long‐term effect of this fixation requires further research. In addition, other internal fixation devices such as the femoral neck system (FNS), four CCS, and DHS are also used in the treatment of unstable femoral neck fractures. Due to limited funds, these devices were not included in the trial control group for comparison, which requires further research in the future.
