33-M/3.2 Metaphyseal, complete, multifragmentary
Definition
Multifragmentary complete metaphyseal fractures of the distal femur are classified as 33-M/3.2.
These fractures are often displaced.
Further characteristics
Children struck from the lateral side, common in sports and pedestrian injuries, often have lateral displacement of the distal fragment and valgus angulation.
Hyperextension mechanisms produce anterior displacement of the distal fragment and apex posterior angulation.
