A normal variant simulating Freiberg's disease.
Radiologic examination of the feet was performed in 72 normal persons with no history or physical signs of disease of the feet. In about 10 per cent, bilateral flat configuration of the second metatarsal head accompanied by a joint space wider than in the neighbouring joints was found, and is therefore a normal anatomic variant that must not be confused with Freiberg's disease or its final stages.
