43t-M/3.1   Simple complete fracture of the distal tibial metaphysis

Simple complete metaphyseal fractures of the distal tibia are classified as 43t-M/3.1.

An associated fibular fracture may have a different configuration, may involve the physis, and is classified separately.

Isolated tibial fractures are often undisplaced, and those with an associated fibular fracture are often displaced.

A transverse fracture is often more stable than an oblique pattern.

Tibial fractures with a fibular fracture at the same level are less stable.

They are usually caused by a direct injury, or indirectly, eg, falls from heights.

Always consider nonaccidental injury in nonwalking children with a tibial fracture.
