Many classification systems have been developed in which trochanteric fractures are assesed as stable or unstable. However, no classification system has proven to be reliable enough for predichng the risk of unstable fracture reduction. I have fore devised the following new classification system.
The system classifies fractures into five types, based on the relation of the dislocation of the two main fragments and posterior comminution. The system was found to be superior to others, as it provided the most reliable information about prediction of the risk of unstable fracture reduction.
