Necrosis is a term we use to describe the death of a bone due to the inability of the blood to be supplied to that bone. There are very specific bones in our body that are more susceptible than others to this process of avascular necrosis or AVN or another name you may hear from is osteonecrosis as well. In particular, the hip is a very common site for this, okay. If a femoral head is a high risk factor for AVN or avascular necrosis. Other places in the body which are high at risk for this include the medial femoral condyle in the knee, as well as the ankle and the elbow as well, and the shoulders or the humeral head.
