Abstract
Vertebroplasty and kyphoplasty are minimally invasive treatments and indispensable
tools in the treatment of osteoporotic compression fractures. This method of treatment
is performed using fluoroscopy or a scanner control an access via the pedicle or the
posterolateral angle of the vertebral body. Vertebroplasty requires a smaller caliber
needle than kyphoplasty, so it is technically easier. Vertebroplasty uses high-pressure
injection, whereas in kyphoplasty the injection is held at low pressure, which together
with the effect of compression on the bone that the balloon produces reduces the risk
and rate of cement leakage. Vertebroplasty is effective in managing osteoporotic compression
vertebral fractures, with improvement in pain and quality of life in the immediate
postoperative period and over the medium term.
Both techniques have a very low complication rate. There is no consensus on whether
the emergence of new fractures in the cases treated by vertebroplasty and kyphoplasty
are related to mechanical variations that were introduced or is a complication related
to the age and evolution of the patient's osteoporosis. Even with this risk of new
fractures, the improvement in quality of life obtained after vertebroplasty and kyphoplasty
treatment is worthwhile. The benefits outweigh the risks.
