Avascular necrosis has been documented following Disseminated Intravascular Coagulation 2 . We are presenting such a case of bilateral avascular necrosis of femoral heads, which interestingly was followed by the spontaneous presentation of the patient's sister with a unilateral avascular necrosis of the femoral head. Both sisters presented with symptoms at the same age. N. Jane Madeley, Mohammed Maqsood, Arshad Bhatti: Hidden Predisposition To Osteonecrosis Of The Femoral Head.

Osteonecrosis of the femoral head involves the hip joint. Osteocytes of the femoral head die along with the bone marrow; resorption of the dead tissue by new but weaker osseous tissue can lead to subchondral fracture and collapse. Two forms of osteonecrosis exist, traumatic (the most common form) and atraumatic. Other terms to describe this disorder include avascular necrosis and ischemic necrosis to denote vascular etiology. The term aseptic necrosis also has been used to indicate that infection does not play a causative role.
