Midfoot Fractures

Mechanism of Injury

These fractures usually arise from falls in which the foot is twisted or forced into equinus, but may also occur from crush injuries.

Classification

Either the navicular or the cuboid may be fractured.

Navicular

• Either the tuberosity or the body may be fractured.

Sangeorzan’s classification system for fractures of the body of the navicular is used:

• Type 1 - Fracture in the coronal plane with no angulation of the forefoot
• Type 2 - Fracture line is dorsolateral to planatarmedial, forefoot is displaced medially
• Type 3 - Fractures with central or lateral comminution.

Cuboid

• Can be avulsion or compression fractures.

Clinical Features

The patient complains of pain following injury. The affected foot is bruised and swollen.

Multiple x-ray views are required to determine the extent of the injury.
