Changes on magnetic resonance images after traumatic avascular necrosis of the femoral head.
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.
