Abstract
Many different systems of classification have been used for fractures of the distal part of the femur, but no one system was so perfect as to describe all the types and to ease the fracture treatment.
Supracondylar-intercondylar fractures of the femurs should be treated separately from other fractures of the distal part of the femurs becasue of their intricate fracture shape involiving the joint surface and associated injuries about the knees.
Authors have experienced two cases of unusual supracondylar-intercondylar fracture. It put another complexion on the classification and treatment.
Therefore it was tentatively named as 5-part fracture of the distal femur, which is not described in any other classification ever proposed.
