Least common complication of fall from height is -: (A) Fracture base of skull, (B) Fracture calcaneum, (C) Fracture fibula, (D) Fracture 12th thoracic vertebra
Answer is C. Fall from height may be associated with fractures of weight transmission axis : -

Base of skull : - Atlanto-axial area
Spine : Dorsolumbar spine
Pelvis and Hip (Proximal femur)

Ankle & foot : Calcaneum, talus, Lower end tibia.

Fall from height is the least important cause of fracture fibula as fibula does not lie in the direct axis of weight transmission.
