Asterisk sign femoral head

Nov 11, 2017  Avascular necrosis (AVN) of the femoral head is an increasingly common cause of musculoskeletal disability, and it poses a major diagnostic and therapeutic challenge. Although patients are initially asymptomatic, avascular necrosis (AVN) of the femoral head usually progresses to joint destruction, requiring total hip Summary The asterisk sign is a stellate density, which is seen normally in the femoral head on computed tomography.

It is due to the demonstration of the trabeculae in the femoral head. Abstract. In computed tomography (CT) of the head of the femur, a starshaped structure can be seen which we refer to as theasterisk orasterisk sign.

The asterisk is formed by thickened weightbearing bone trabeculae.
