title: [Research advance of dynamic hip screw internal fixation in treatment of intertrochanteric fractures].
abstract: 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.
  
  
  CONCLUSIONS
  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.
