title: Changes on magnetic resonance images after traumatic avascular necrosis of the femoral head.
abstract: We describe two cases of avascular necrosis after traumatic fracture of the femoral neck. The size and signal intensity of the necrotic areas changed on follow-up magnetic resonance images. Magnetic resonance imaging is suitable for showing resolvable changes that radiographic study cannot demonstrate during the clinical course.
