Freibergs Infraction


Flattening and sclerosis of the distal second metatarsal articular surface


Avascular necrosis of the second metatarsal head. Likely related to chronic repetitive trauma. Possibly related to high heeled shoes. Similar findings can be seen in other metatarsals.

Radiographic findings include subchondral lucency initially with progression to sclerosis and fragmentation with collapse leading to a flattened appearance.

Osteotomy may be required for treatment.
