Patients with osteoporotic fractures of the spine and some tumours of the spine are amenable to treatment. A vertebra may collapse due to these conditions. It is now possible to insert a cannula into the pedicles of damaged vertebrae. Balloons can then be used to inflate the vertebra and the cavity can then be filled with bone cement.
Vertebroplasty is a similar technique to Kyphoplasty but, instead of using a balloon to expand the bone, cement is injected under pressure. This is generally more useful if there has not been significant collapse.
