Answer. D.
The image shows a fracture of the vertical lateral condyle
Tibial
plateau injury:
Fractures of the tibial plateau are
caused by a varus or valgus force combined with axial loading (a pure valgus
force is more likely to rupture the ligaments). This is sometimes the result of
a car striking a pedestrian (hence the term ‘bumper fracture’); more often it
is due to a fall from a height in which the knee is forced into valgus or
varus.
The fractures are classified based
on Schatzker classification.
Type 1: vertical split of lateral
condyle
Type 2 – a vertical split of the
lateral condyle combined withdepression of an adjacent loadbearing part of the
condyle
Type 3 – depression of the
articular surface with an intactcondylar rim
Type 4 – fracture of the medial
tibial condyle (as shown in the image in MCQ)
Type 5 – fracture of both condyles
