Objective: To investigate the development of dynamic hip screw (DHS) internal fixation in the treatment of intertrochanteric femur fractures.
Methods: The latest relevant articles were reviewed extensively, including biomechanics and clinical application research.
Results: DHS is the effective selection for the treatment of intertrochanteric femur fractures, especially by the innovation of DHS structure, operative manipulation.
Conclusion: Treatment of intertrochanteric femur fractures with DHS is still a gold level, but strict selection of patients, proficiency operation and invasive manipulation are the most essential principles.
