13-M/3.2 III and IV   Multifragmentary metaphyseal, complete with/without contact between fracture planes

The patterns of these fractures are characterized by a complete multifragmentary metaphyseal fracture with varying degrees of displacement. These fractures typically appear in children approaching skeletal maturity, following high-energy-transfer injuries.

This is a multifragmentary metaphyseal fracture (13-M/3.2 III), unusually in a 7-year-old child.

Older child (older than 6 years):

• Completely displaced fracture (13-M/3.2 IV)
• No contact between fracture planes
• Small additional fragment

Older child (12-year-old):

• Completely displaced (13-M/3.2 IV)
• No contact between fracture planes
• Large third fragment makes reduction intrinsically unstable
