Minimally invasive technique versus conventional technique of dynamic hip screws for intertrochanteric femoral fractures

摘要

Introduction Intertrochanteric fractures of femur are common in elderly patients. The compression hip screw has become the predominant method for osteosynthesis of intertrochanteric fractures. However, the conventional dynamic hip screws (CDHS) technique has some disadvantages. Recently, we have used a minimally invasive dynamic hip screws (MIDHS) technique to reduce these disadvantages. This prospective study is to compare curative effect of MIDHS with that of CDHS with open reduction on Evans type 1 intertrochanteric fractures.
