There are several differences between vertebroplasty and kyphoplasty. However, both procedures are vertebral augmentation techniques.
We already have an article on indications of vertebroplasty
8 differences between vertebroplasty and kyphoplasty
1. Synonym: Vertebroplasty is also known as percutaneous cementoplasty. On the other hand, kyphoplasty refers to as ballon vertebral augmentation.
2. Thus, balloon catheter is a must in vertebroplasty but not in kyphoplasty.
3. In vertebroplasty, the PMMA bone cement has high pressure, low volume and low viscosity. On the other hand, cement in kyphoplasty has low pressure, high volume and viscosity.
Hence, other differences between vertebroplasty and kyphoplasty are
4. Increase in operative time in kyphoplasty
5. Elevation of radiation exposure and subsequent radiation hazard in kyphoplasty.
6. However, there is increase in cement leakage in vertebroplasty. This is because, balloon catheter in kyphoplasty prevents this phenomenon.
7. The most important variance is the restoration of vertebral height. Vertebroplasty is inefficacious in restoring height than the latter.
8. Finally, there is significant increase in risk of fracture in adjacent levels in kyphoplasty.
