Bone augmentation in metastatic cancer. X-ray of a section through the left hip of a 59-year-old female patient undergoing a plasty procedure to repair damage to the pelvic bone caused by cancer that has spread (metastasised) from the breast. During the procedure, bone cement (bright area, centre) is injected through a small hole in the skin into the damaged bone. Here, the trocar (tube, white right) can be seen injecting the cement into the acetabulum of the pelvis.
