Abstract:
Objective To introduce a new classification system for femoral intertrochanteric fractures and propose classification to assist surgical management.Methods A total of 176 cases of femoral intertrochanteric fractures treated from September 2007 to October 2011 were enrolled in the study.X-ray and three-dimensional spiral CT reconstruction were performed to define fracture shape,location,number of major fragments and displaced direction.As combined with the intraoperative findings and cadaveric anatomical study,the femoral intertrochateric fractures was simulated using a three-dimensional entity of normal proximal femur produced by Mimics 11.1 program.A new classification system for femoral intertrochateric fractures was proposed.Results The new system categorized intertrochateric fractures of the femur into five types (Type Ⅰ,Type Ⅱ,Type Ⅲ,Type Ⅳ and Type Ⅴ) based on the integrity or destruction of the medial column,lateral column and posterior column set and divided on the basis of bone connection of femoral head-neck fracture fragments with the bone in intertrochanteric region.Conclusions The new classification system with introduction of three-column concept is brief and practical and has a clear definition of fracture stability.Besides,the new classification-based treatment is recommended.
