Bone death. Coloured frontal magnetic resonance imaging (MRI) scan of a male patient with severe osteonecrosis (bone death) in both legs. The bones at upper left and right (dark blue) are femurs (thigh bones), with the tibias (shin bones) at bottom (not clearly seen). The dead areas of tissue are at lower left and right (green). The bone death results from a loss of blood flow to the area, known as an infarction. Osteonecrosis causes causes pain and swelling. Treatment is with pain relief and exercise. In severe cases, surgery may be needed to remove the dead tissue or replace the joint.
