Seinsheimer classified fractures of the distal femur using a scheme based on the pattern of involvement. The author is from the Massachusetts General Hospital.
Parameters:
(1) involvement of the lateral condyle
(2) involvement of the medial condyle
(3) involvement of the supracondylar distal metaphysis
(4) displacement
(5) comminution
